    at , i dont understand how you decided a is the answer,,, it doesn't accomodate the technology, efficiency and calculability... i understand that its expected as the destination is a popular attraction place, but for the rest of the criterion, how does it relate?

      I was confused with the result of this question as well but I'll try to explain how I understood why the answer is A and not B. The question asked what a rationalized travel agency would do and the passage defined rational "as the pursuit of efficiency, predictability, calculability, and control through technology." Choice B is partially correct because it states the use of computerized systems which is in line with the passage's definition of rational but the rest of the statement is incorrect. The rest of choice B states "... provide low cost customized itineraries." The "low cost" part can be found in paragraph 2 but is used in the context of irrationality as that paragraph is meant to expound on the last sentence of paragraph 1. The "customized itinerary" is also not aligned with rationality because the process would no longer be efficient or predictable. Customization requires time and energy and is not easily predictable because the customer can change their mind at a moment's notice.

      Choice A is the best selection because it is efficient, predictable, easily calculable, and processed through a computer system. Think of choice A as a guided tour package to a European city offered by a travel agency. This package comes complete with airfare, transportation to and from set popular attractions, hotel/lodging, and meals (maybe) for a set price for each person. This makes booking a trip efficient and predictable for both the customer and agency. Since the pricing is set, customers can easily calculate their total vacation cost; the travel agency can know how much profit and operating cost that guided tour package will bring; and the experience will be predictable as the itinerary is the same for all customers and is given before purchase. Since the passage also discussed technology to an extent, we can assume some form of computerization is involved with choice A.

      Sorry this answer was a bit long but hopefully explained my thought process into how I rationalized why A was correct and why B was wrong.

    - I would argue that A actually is the better answer based the following:

    1) Paragraph 4 explicitly mentions job dissatisfaction in the fast food industry.
    2) The last sentence of the passage proposes dissatisfaction with suburban communities.
    3) The question says "people today", and not "people in the 1950s and '60s" (when the suburbs in question were established). Ritzer also suggests in paragraph 3 that fast food companies may no longer gravitate toward collective-minded employees.

    Tests are often a reflection of the maker as well as the taker, so I'm grateful that these videos allow viewers to see questions from the maker's perspective.

    At , couldn't you argue that option C is also not directly supported by the text? The evidence that the editor underlines to prove answer C does talk about how there are certain scenarios that can lead to interchangeability but the workers nor the suburban residents "allow themselves" to be interchangeable in either case. The passage does not state that the workers or residents believe that they themselves are interchangeable, but that their position implies that they are interchangeable to those in charge.

      From another approach, the passage's main idea is the sameness and the predictability caused by the rationalization of society. So the idea that "ppl allow themselves to be treated as interchangeable" makes sense because it is closer to the main idea. Of course A can also be attempting, but it is further from the main idea of the passage than C. You have to choose the better answer but not the most correct answer, if that makes sense.

    This method is so different from what I have been doing. Do you recommend highlighting WHILE reading the passage, or reading the paragraph followed by highlighting of that paragraph? I figured it would take too much time to do this. Or did you do this, only for the purpose of the video? Thanks in advance.

      It might be better to highlight after reading a paragraph, so you have an idea what the passage might be about. When I try to highlight while reading, I end up realizing that another sentence may have been more worthy to highlight. Highlighting after reading is better since you have an idea what the main ideas are.

    For Option C in the last question (), why can we assume that turnover rate in entry-level assembly line workers is high? Isn't that outside information?

      No, because you are assuming that the employee responses apply to entry-level assembly line workers as well. In the first sentence of paragraph 4, it is mentioned that turnovers are a method of response from employees. As you continue reading paragraph 4, you see that the fast food industry has the highest turnover rate out of all the businesses in the U.S. So this information that is stated can be applied to entry-level assembly line workers. Because we know that turnovers are an employee's response to the work and the turnover rate is high in the fast food business, we can also assume that the turnover rate for the entry-level assembly line workers to be high as well. Hopefully this helps! :)

Video transcript

- [Voiceover] The purpose of this video is to show you how I approach reading and answering questions on an example Critical Analysis and Reasoning Skills passage. The name of this passage is "Living in a rational society." I'm gonna read through the passage first, and when I notice important sentences or signal words, I'll let you know that I'm highlighting them. "The rationalizing of society can be conceptualized as the pursuit of efficiency, predictability, calculability, and control through technology. But rational systems inevitably spawn a series of irrationalities that result in the compromising and perhaps even the undermining of their rationality." Okay, so that first sentence seems pretty important because it gives a definition for the term "Rationalizing of Society" which is also mentioned in the title of this passage. So I'm gonna highlight that sentence. I'm gonna wait and see if the point about irrationalities made in the second sentence seems important after I read some more. "Fast food restaurants, which epitomize the rational model, prefer the fastest means of getting from a hungry state to a sated one, without surprises, at low cost and in a carnival like setting, suggesting that fun awaits the consumer at each visit. The wholesomeness of the food seems an insignificant consideration. Whereas in the past working people were prepared to spend up to an hour preparing dinner, they are now impatient if a meal is not on the table within ten minutes. For their part, some fast food restaurants have developed chairs that become uncomfortable after about twenty minutes to ensure that diners do not stay long." So here the author signals that fast food restaurants are the epitome, or ideal example of a rational system. I'm gonna highlight that part of the first sentence. Then the rest of this section seems to be explaining which features of fast food restaurants make them such a good example. "Fast food restaurants have preferentially recruited adolescent help; at least until recently, because this age group adjusts more easily than adults do to surrendering their autonomy to machines, rules and procedures. Few skills are required on the job, so workers are asked to use only a minute portion of their abilities. This policy is irrational from the standpoint of the organization, since it could obtain much more from it's employees for the money, however negligible it pays them. These minimal skill demands are also irrational from the perspective of the employees, who are not allowed to think or to respond creatively to the demands of the work. These restrictions lead to high levels of resentment, job dissatisfaction, alienation, absenteeism and turnover among workers in fast food franchises. In fact, these businesses have the highest turnover rate of any industry in the U.S. The entire workforce of the fast food industry turns over three times in a year. Although the simple repetitive nature of the work makes it easy to replace those who leave, the organization would clearly benefit from keeping employees longer. The cost of hiring and training are magnified when the turnover rate is extraordinarily high." So these two paragraphs tell us more about the features of fast food restaurants that are consistent with the rational model. But here we also see the theme of irrationality emerge. So I'm gonna go back and highlight that theme that we saw mentioned in the second sentence. I'm also going to highlight where evidence for that theme is mentioned here. Finally, we are told what some negative consequences of the rational model seem to be. The first sentence of the fourth paragraph summarizes these negative effects. So I'm gonna highlight that first sentence. Now let's continue with the passage. "The application of the rational model to the house-building process in the 1950's and 60's led to suburban communities consisting of nearly identical structures. Indeed, it was possible to wander into the residence of someone else and not to realize immediately that one was not at home. The more expensive developments were superficially more diversified, but their interior layouts assumed residents who were indistinguishable in their requirements. Furthermore the planned communities themselves looked very similar. Established trees are bulldozed to facilitate construction, in their place a number of saplings, held up by posts and wire are planted. Streets are laid out in symmetrical grid patterns with such uniformity suburbanites may well enter the wrong subdivision or become lost in their own." So in this section the author turns to a new example: House building. I'm gonna highlight the first sentence to remind me where this new topic starts. Then the remainder of this section seems to be describing how elements of the rational model can be seen in this new context. Let's see where the passage goes next. "Many of Steven Spielberg's films are set in such suburbs. Spielberg's strategy is to lure the viewer into this highly repetitive world and then to have a completely unexpected event occur. For example, the film Poltergeist takes place in a conventional suburban household in which evil spirits ultimately disrupt the sameness. The spirits first manifest themselves through another key element of the homogeneous society, the television set. The great success of Spielberg's films may be traceable to a longing for some unpredictability, even if it is bizarre and menacing, in increasingly routinized lives." At first it's unclear what Steven Spielberg's films would have to do with the rest of the passage. It seems like a digression or a departure from the author's main point. But then the last sentence is important because it gives us a reason why the author goes into this example. I'm gonna highlight that sentence. It's used to show how routinized lives, as dictated by the rationalized model, may not be satisfying for people. Finally we see the reference for this passage, "Adapted from G. Ritzer, The McDonaldization of Society Copyright 1993 by Pine Forge Press. Question one. The author's argument suggests that the primary motive of employers who make humans work with machines is to: A. Improve the quality of their products. B. Reduce the cost of wages and benefits. C. Avoid seeming to be behind the times. D. Increase the uniformity of procedures. This question is asking you to summarize or paraphrase what the author suggests is the primary motive of employers who make humans work with machines. Because it's asking you to summarize a specific phrase or idea from the text, this is a "Foundations of Comprehension" question. Since the question is about employers, this suggests that the answer to the question's going to be found in the first part of the text, about the fast food industry rather than the second part of the text about house-building. Option A suggests that employers are motivated to improve the quality of their products. In paragraph Two, the only part of the text that comes close to discussing quality is the sentence that says "The wholesomeness of the food seems an insignificant consideration.." This suggests that the author believes quality of a product is not an important motivation. Thus it doesn't appear that option A is a good answer. Option B suggests that employers are motivated to reduce the costs of wages and benefits. Although the author mentions that fast food restaurants offer products at low cost, there's no discussion about trying to reduce the cost of wages and benefits with machines. So it doesn't appear that option B is a good response. Option C says that employers are motivated to keep up with the times, but there's nothing in the passage that suggests that employers are trying to stay current, or seem innovative or cutting edge. So it doesn't seem that option C is a good response. Option D suggests that the employer is motivated to increase uniformity. The opening sentence mentions control through technology. In the second paragraph the author cites the desire to avoid surprises for the consumer. In the third paragraph the author cites employer preference to hire employees that are comfortable with surrendering their autonomy to machines, rules and procedures. All these examples are consistent with the claim that the employer has control and uniformity of procedures as the main goal in using machines. Thus, there is some evidence in the passage to support option D, and it seems like the best answer. Question two. "A common thread in the discussion of fast food and the discussion of suburban housing is that people today: A. Are increasingly resistant to the regimentation of life. B. Expect their needs to be met at the lowest possible cost. C. Allow themselves to be treated as interchangeable. D. Are unable to discriminate among products that differ in quality." This question is asking you to identify a central theme or idea from the passage. This means it's a "Foundations of Comprehension" question. Option A says that people are becoming increasingly resistant to regimentation. Skimming through both the fast food and the housing sections there's nothing suggesting that individuals are resisting regimentation of life, nor that they are increasingly resistant. So it doesn't appear that this is a good response. Option B says that people expect their needs to be met at the lowest possible cost. Although the discussion of the fast food industry suggests that consumers expect their fast food at low cost, there's no discussion of people expecting low cost in suburban housing. So it doesn't appear that option B is a common thread across the two situations. Option C says that people allow themselves to be treated interchangeably. There does seem to be evidence for this being true of the fast food industry. In paragraph three, it describes fast food employees as being willing to surrender their autonomy to machines, rules and procedures and to work in jobs where they are not allowed to think or respond creatively. In paragraph four it says, "the simple repetitive nature of the work makes it easy replace those who leave." Then in paragraph five the passage details a number of ways that people allow themselves to be interchangeable in terms of suburban housing. People live in nearly identical structures, and builders assume residents are indistinguishable. So option C seems to be a good answer. However, before selecting it we should examine whether option D is better. Option D suggests that people are unable to discriminate quality. In the fast food portion of the passage, the author suggests that wholesomeness of food seems an insignificant consideration. However, just because people do not consider the quality of their fast food it doesn't mean they cannot discriminate it. Further, as we read through the suburban housing portion of the passage, we see there's no discussion about quality in home construction. So it doesn't appear that option D is a common thread, and option C seems the be the best answer. Question three. "Information in the passage suggests that a rationalized travel agency would emphasize: A. Planned tours to popular attractions with accommodations at large hotels. B. Computerized systems to provide low-cost customized itineraries. C. Personnel trained to make reservations but with little experience as travelers. D. Procedures that encourage problem solving initiatives by managers." This question introduces a new idea that was not mentioned in the passage. It asks you to imagine a rationalized travel agency. Because you're being asked about a new context, this is a "Reasoning beyond the text" question, which means it wants you to either apply or extrapolate the ideas in the passage to the new situation. Returning to the definition of a rationalized system that we highlighted in the first sentence, we would expect a rationalized travel agency to emphasize the pursuit of efficiency, predictability, calculability and control through technology. We would expect standardization for a large group of consumers. Option A offers planned tours to popular destinations and accommodation in large hotels. This fits well with the rationalized approach, so option A would seem to be a good answer. Option B suggests the use of computerized systems to produce low cost customized itineraries. The use of computers is obviously a form of technology which is mentioned as an aspect of a rational model. However, customized itineraries would represent the opposite of the rational model, because they would offer individual variations rather than predictability and sameness. So option B does not appear to be a good response. Option C suggests that employees might be trained to make reservations, but have little travel experience. The passage does not discuss using employee background including prior experiences or lack of prior experiences as part of personnel decisions under the rational model. So it doesn't appear that option C is a good response. Option D says that the rationalized travel agency would emphasize problem solving among managers. However, passage says that under the rationalized model employees are not allowed to think or respond creatively to the demands of work. It does not discuss different practices for senior level employees such as managers. Thus there's no support in the passage for option D. Option A is the answer that has the most support from the passage. Question four: "Suppose that the employee responses to working conditions in fast fast food franchises paragraph four also apply to entry-level assembly line workers. In light of this information, the author's main point in mentioning these responses is: A. Weakened, since the fast food industry is not unique in suppressing creativity. B. Weakened, since the monotony of work is not necessarily related to employee dissatisfaction. C. Strengthened, since predictability and employee turnover are associated in another context. D. Strengthened, since low wages and job dissatisfaction are associated in another context." This question starts with the word "suppose". That is a good clue that this is a "Reasoning beyond the text" question, which means that it wants you to apply or extrapolate the ideas in the passage to a new situation. Or to think about how new information would affect the ideas in the passage. The passage uses the fast food industry as an example. The author described employee responses to working conditions in the fast food industry in the sentence we highlighted at the start of paragraph four. "These restrictions lead to high levels of resentment, job dissatisfaction, alienation, absenteeism and turnover among workers in fast food franchises." The term "restrictions" in this sentence refers to the previous sentence where it says that employees are not allowed to think or respond creatively. If this pattern also seen in another context, such as entry-level assembly line workers, then the authors main point would be strengthened, not weakened as proposed in options A and B. So those do not seem like good answers. Both options C and D do state that the authors main point would be strengthened. Option C describes the authors main point as being a connection between predictability and turnover. This is consistent with the ideas in the highlighted sentence, suggesting that turnover is related to being restricted to only using a standard set of routines. So there is support for option C. Option D describes the authors main point as being a connection between low wages and dissatisfaction. However, the passage does not discuss low wages as one of the reasons why employees may be dissatisfied. Thus, option D does not seem like a good answer, and option C is a better answer.
