Reading Comprehension - Worked Examples

Video transcript

the passage provides the strongest support for believing that some scientist the 1920s held which one of the following views regarding Payne's interpretation of the spectroscopic data relating to the Sun okay so that's a that's a big long question let's sort of focus on what exactly it is it's a question that is about support for believing that some scientists a group in the 1920s held which of the following view so it's is the views of a group and what are the views about they're about paints interpretation of the spectroscopic data relating to the Sun ok so if you recall them the main point of the entire passage was a scientist didn't accept Payne's claim about the composition of a Sun so we can head up to the passage and see what we can hunt down about the views of the various groups mentioned but this is a question that's asking you to find support about a certain groups views and it's a fairly common question type so let's go up until we can find beyond just hearing remembering that that you know most of the scientists believe that this hurry her interpretation of a spectra to have a de relating to some was actually just you know wrong so let's see if we can find me we're going to go through the whole passage and see what kind of views are mentioned so first we have you know strong resistance among professional astronomers to her to her position to her to her claim so we're looking for generally a negative thing we have another view here we hear about the Orthodox of you about you being iron to composition with the Sun if we're looking for other people who hold views we have Lord Kelvin who's holding a view about or you know how does it an idea about how the Sun is made of iron and how that iron could compress itself and make the Sun hot let's look at what other views we have in this paragraph we have preliminary examination of the spectroscopic data convinced pain because this paragraph is about about pains analysis of the spectroscopic data so okay here we are most astronomers at the time dismissed a interpretation was the earth answer we got a we have minuses from most astronomy astronomers and some sought to explain it away something by cleaning that what she had examined was data about the sun's outer surface rather than its interior so here's your some or some astronomers and we have most astronomers let's see what we can find and the choices are going to help us cross them out or choose the right answer so a the meta melody she use in analyzing the data was outdated and thus her findings were of doubtful validity okay so we do we know that a lot most of the Strada Murs think that our findings are doubtful validity but are they are they claiming that her methodology for analyzing the spectrographic data is how dated I think the word outdated is what's making this choice long so let's could it be her interpretation of the data was remarkably accurate and prove that the traditional interpretation of the needed be incorrect okay remarkably accurate that's a that's a big double plus and we didn't hear a lot of big double pluses from any views in support of Payne's claim so that's out see her findings are generally promising and wanted serious consider it warranted serious consideration didn't hear generally promising but know that definitive assessment of them could be made without verification of certain details nobody's saying that our findings are generally promising that's out D her interpretation of the data was not entirely he'll founded because it was based on the spectrographic data but the overall conclusion secret from the data were wrong okay so that's looking pretty good let's look at he her interpretation and the overall conclusions he drew from it were correct no no we don't hear any astronomers saying that they hold the view that she was correct in fact if we look at D the overall conclusions she drew from the data were wrong yeah we we heard that some astronomers think that she must have just been looking at the surface of the Sun but really wasn't seeing any information about the interior of the Sun and so she was basically wrong so this is our answer D
