Video transcript
- [Narrator] This question starts out the dialogue between Huang and Suarez most strongly supports the claim that they disagree about whether, so we're looking at a
question that wants us to infer a dispute. One of the choices will be a claim that we can reasonably
say the two speakers disagree about. The other four choices will be a claim that we can't infer a disagreement about either, because one or
both of the speakers doesn't have an opinion about it, or because they agree on it. Pause your video now if you'd like to try this question on your own otherwise, let's move
on to the explanation. Okay, let's read this stimulus together and as we do, you don't need to commit everything to memory, just really understand the main conclusion and evidence of each speaker's argument. Huang says, "Most people
who commit violent crimes do not carefully consider whether or how they will be punished for these crimes. And those who don't commit violent crimes have no inclination to do so. Rather than impose harsh
mandatory sentences, we should attend to the
root causes of violence to reduce the rate of violent crime." Suarez then responds with,
"Would you say the same about nonviolent crimes,
such as tax evasion? Surely mandatory penalties are a useful deterrent in these cases. At any rate, I am confident
that mandatory sentences prevent most people who would
otherwise physically harm others from doing so." We don't generally make
a strong prediction for questions like these because their could be
any number of things that the two speakers disagree on. So pigeonholing yourself into
one of these possibilities isn't usually very helpful and
it could actually be harmful. Instead, it can often be
effective for you to evaluate each choice, one at a time,
to determine a few things. First, you want to know
what the first speakers thinks of the choices claimed. For example, let's look at A together. We could say, "Huang, do
you think the best way to reduce violent crime is
to address the root causes of violence?" Huang's answer would either be yes, no, or "I have never addressed this". In this case Huang would say,
"I have never addressed this." Be careful here. It's true that Huang wants
to reduce violent crime by addressing the root causes of violence but Huang never says that's the best way only that it's a way that's preferable to imposing harsh mandatory sentences. So we can put a question
mark here on test day to show that we can't infer
Huang's opinion on this. As soon as you determine
that one of the speakers would respond to the choice
with, "I didn't address this", you can eliminate the choice and move on without considering what
the other speaker thinks. That's because in order
for two people to disagree or agree about something,
they both have to have an inferrable opinion on it. If someone says, "I love
apples", for example, we can't infer whether that
person thinks that apples are the best fruit in the world, whether apples are better than oranges. We can only infer a favorable
opinion about apples. Makes sense? Alright, let's evaluate the next choices. B: We could ask Huang,
"Do you think that people who commit violent crimes
deserve harsh punishment?" Well, Huang doesn't have
an answer to this question because the idea of what people deserve isn't an issue that's ever
addressed by either speaker. So we can cross this one off, too. C: Let's ask Huang, "Do people
who commit violent crimes carefully consider how
they will be punished for their crimes?" Well, Huang doesn't
think that this is true most of the time based
on the first sentence. So Huang's answer would be a no. We can use a minus sign to
show that Huang disagrees and now we can move to Suarez. "Suarez, do you think that
people who commit violent crimes carefully consider how
they will be punished for their crimes?" Well, Suarez doesn't address this. Suarez believes that mandatory sentences prevent most people who would
otherwise physically harm others from doing so but
never addresses whether people who do commit violent
crimes carefully consider their punishment. Suarez is a question mark so that means we can eliminate choice C. For choice D, let's ask Huang, "Do you think that mandatory
sentences will deter most people who might otherwise
commit violent crimes?" Huang would answer, "No." How can we infer this if it
was never stated explicitly? Well, it's because Huang
is basically arguing that mandatory sentences don't work, that people committing violent crimes wouldn't think about the
mandatory sentences anyway and people who don't commit violent crimes weren't going to commit
violent crimes anyway, regardless of the mandatory sentences. So Huang's answer is, "No". What would Suarez's answer be? Would mandatory sentences
deter most people who might otherwise commit violent crimes? Suarez would answer with, "Yes". Choice D is simply a paraphrase
for the last sentence in Suarez's argument and so because we can reasonably
infer that one of the speakers would disagree with choice
D and that the other speaker would agree with choice D,
then this is our answer. For the record, choice E, which is a claim that severe penalties reduce the incidence of tax evasion, doesn't work because Huang never
expresses any kind of opinion on tax evasion. So to recap, you don't
need to formulate an answer before evaluating the choices
on Infer the Dispute questions ,you simply want to understand
each speaker's argument and then find the choice with
which one speaker would agree and the other would disagree. Remember that a claim cannot
be a point of disagreement or agreement if one or
more of the speakers never even addresses that statement or implies anything about it. Finally, keeping short
notes on what the speakers each think can be helpful as
you go through the choices. We can use a plus sign for agree, a minus sign for disagree and a question mark for no opinion.
