The GMAT Official Guide 2019 Edition, Part 3


Manhattan Prep GMAT Blog - The GMAT Official Guide 2019 Edition, Part 3 by Stacey Koprince

The new GMAT Official Guide 2019 edition (OG) books have landed and I’ve got the scoop for you! (If you’d like, you can start with the first installment of this article series.) Today’s post focuses on the Verbal questions in the big OG.

Reading Comprehension in the GMAT Official Guide 2019 Edition

We gained 6 new Reading Comprehension passages and lost only 4—but we have the same number of new and dropped questions (21). So we just have a lower question-per-passage ratio in the new book. (And I think that’s a good thing. The real test typically only gives us 3 or 4 questions per passage, so I’d rather have more passages with fewer questions in the GMAT Official Guide, too.)

Of the new passages in the GMAT Official Guide 2019 edition, 2 are business-based and 4 are science-based. (On my last official test, in January of 2017, all 4 of my passages were science-based!) Two of the science passages are wow-hard in terms of vocabulary/complexity, in my opinion. One’s about types of cacti in the Sonoran desert and the other is about conodonts. (What? I had no idea what conodonts were, either. They’re eel-like creatures—or they were. They’re now extinct.) Anyway, save those two passages for later in your studies; they’re seriously hard.

My favorite new passage is the one that begins When asteroids collide…because, c’mon, who wouldn’t love that as the title of a new reality series?? 😄 Seriously, though, this one’s decently challenging as well. And our fourth new science passage is about the substance amber.

One of the two business passages is also pretty complex—the one about monetizing ecosystems. Again, I’d save that one for later in your studies.

All in all, GMAC (the organization that makes the GMAT) has given us some really great hard Reading Comp material to test our skills. I’m excited to start using some of this with my students.

Critical Reasoning in the GMAT Official Guide 2019 Edition

The GMAT Official Guide 2019 edition added and dropped 19 Critical Reasoning questions, with no notable changes in specific categories or question sub-types. There are several interesting, harder questions—and some very good lessons to learn from the new problems.

For example, a Strengthen the Argument question, #589, includes the wording “in order to address this problem…” When you see something like this, make sure you glance back to remind yourself what that problem is! In this argument, the contention is basically that one problem is causing another problem—and that they’re planning to fix the first problem in order to address (fix) the second one. If you don’t catch that full significance, you might fall into a trap on this one.

I also think #631, another Strengthen question, is super interesting. I wasn’t expecting the correct answer that they gave—but the logic is completely solid. I don’t want to give anything away, so I’ll say it this way: I assumed that certain information was the “main” information (and therefore what I should think about as I looked for the answer), but the correct answer turned out to hinge on a piece of information in a premise…and that info seemed like just a small detail. They did a good job of disguising the ultimate importance of that detail.

And #656, an Explain the Discrepancy question, is a great new one, too. The logic is again entirely rock-solid but you do have to take a couple of logical steps in the analysis to see why the correct answer really does explain the situation.

All in all, there are some good learning opportunities in the new Critical Reasoning questions.

Sentence Correction in the GMAT Official Guide 2019 Edition

The GMAT Official Guide 2019 edition added and dropped 21 Sentence Correction questions. I saw one thing that surprised me a bit (more below), and I did note that meaning, modifier, and sentence structure issues showed up in quite a number of the new problems. In fact, by my count, only 4 of the new problems did not have any one of those issues going on—so I’m definitely going to be making sure that my students are paying lots of attention to these three issues.

I was intrigued by #745. The sentence structure is on the more complex side and at least one answer choice contains some subtle redundancies. (I’m not going to tell you exactly how many answers because I don’t want to give too much away!) From a meaning perspective, it’s very important to make sure that the sentence is clear and logical—and that it doesn’t repeat itself unnecessarily. This one also hits the sentence structure category and one other.

Problems #763 and #799 teach a very good lesson: Don’t cross something off just because it “sounds funny”—if you’re not actually sure why it’s wrong. For both of these problems, I think a lot of people will think the correct answer sounds funny—but it’s still correct!

Let’s talk about the question that surprised me a little, #781. The correct answer uses a particular grammatical construction that doesn’t strictly follow the patterns we’ve typically seen on the GMAT. But the usage of this thing (I’ll tell you what it is in a minute) has become more common in spoken language, so I think they’re signaling that this is fine on the GMAT, too.

I can’t give you the actual text of the correct answer, but here’s a similar example:

The hurricane will continue to develop while an area of high pressure spreads, which will cause torrential rain and possible flooding.

(I’m making this up; I have no idea how the weather really works!)

Have you studied “comma-which” modifiers yet? If so, you’ll know that a comma-which modifier generally refers to just a noun, and that noun is usually right before or very close to the “comma-which.”

In this problem, the verb spreads intervenes between the noun and the comma-which modifier—that’s unusual for the GMAT. You can certainly have, in certain circumstances, some words that intervene between the noun and the comma-which modifier, but usually (on the GMAT) we see other nouns or prepositional phrases in between, not verbs.

For example, this is correct: The box of nails, which is on the table, belongs to Sadik. In this example, the comma-which modifier refers to box, not nails, because the singular verb is must go with the singular noun box.

In the hurricane example above, we can say that the modifier refers to the noun phrase an area of high pressure, skipping over the intervening verb spreads just as we skip over the intervening words of nails in the other example. The area of high pressure will cause all the rain and flooding.

So which questions are the new ones in the whole GMAT Official Guide 2019 edition?

I’m so glad you asked! In part 4 of this series, I’ll give you the list of questions that are new to each chapter of the big OG. Until then, happy studying!
