Hello my name is Kevin and I'm here from Magoosh. Let's dive into reading comprehension.
In the official guide to the GMAT we're looking at question number one, the very first one. Uh we're in
this book um there are newer official guides but you'll find this question in there as well. um the
previous video we did was about the passage so now we're diving into question number one. so one thing
to review for before we dive into the question is the uh what we discussed in the previous video.
um we went over the main idea which is uh there's two theories about fish schooling. we talked about
the structure uh first paragraphs the intro, second paragraph talks about idea or theory number a not
number a idea a um, and then paragraph number three is the critics of theory a and then introduces
theory b and then the fourth paragraph is all about theory b the confusion effect. and then
we talked about the tone this is balanced-ish um and that the authors basically just
presenting two theories of schooling. um so question number one, I'm gonna just read
straight from the passage because that's easy.. um the question says: according to the passage theory
b states that which of the following is a factor that enables the schooling fish
to escape predators great so um this question is a detailed question um I know that because
of the phrase according to the passage and when I know i'm dealing with a detail type question I
know there's certain things I need to do. um this is my plan first one attack the passage which we
already did uh second one we're going to rephrase the question which we can do right now.
the question is basically just asking what does theory b say about schooling and escaping
predators then I'm going to do some research in the passage I'm going to anticipate what an
answer might sound like so sort of predict what the answer might be and then finally step five
go into the answer choices eliminate wrong answers until I arrive at the right answer. okay
um one other thing to remember is that uh they like to have common wrong answers with specific
question types. so with detailed questions we have three typical wrong answers one an inference if
an answer choice is making an inference it's wrong because we're looking for a detail in the passage
which means it'll be written in the passage somewhere. a distortion of the passage where
they take something in the passage and twist it make it wrong just a little bit
and then finally when they introduce new information. sometimes it's related to
what the topic is but it isn't in the passage at all so keep an eye out for the new information.
okay let's dive into the answer choices so answer choice a uh mentions compact groups as
a reason and this is a distortion of the passage compact groups that's just what schooling is but
it doesn't that's not what theory b is talking about theory b is explaining why compact groups
would help the fish to avoid a predator so this is a good example of a distortion we can eliminate it.
uh answer choice b is awesome it is the right answer because they mentioned movement of the fish
and I know I'm looking for theory b so I'm looking
in the fourth paragraph for an answer and if you look in lines 35 to 40 that's where you find the
description of how the movement of the fish uh allows them to avoid being chomped on by predators.
um answer choice c inability to detect uh this is a distortion of the passage because this is what
theory a says so this is a perfect example of how they're distorting the passage we have
a question that's asking about asking about the second theory and they provide an answer choice
that is about the first theory. so they want to make sure you're paying attention and reading
closely and know what they're actually asking about because you would find this in the passage
but it's not related to theory b it's related to theory a uh and question or answer choice d
says that uh the fish can hide behind each other which is an interesting concept but not
mentioned in the passage we have no details and no information about fish hiding behind each other.
And then finally answer choice e that the fish can move with great speed, um maybe that might be
a reason but it's not brought up in the passage there's nothing in the fourth or third paragraph
where we learn about theory a or theory b excuse me um where the fish move really fast and that
helps them to avoid the predator so this is new information not included in the passage, so
easy to eliminate. All right all you GMAT studiers I hope this was helpful if you have any questions
