Hi Saurabh, Answers (A) - (C) are wrong because the initial "they", in the clause preceding the comma, refers to "travelers". It makes more sense for that "they" to refer to "customs inspectors", as it does in (D) and (E). There are several problems with (E): ...

The first option is correct. The logic of this is that friends (more than one friend) helped you, and that I am one of them.

Hi Pankaj, You're right to say that "equally as" is unidiomatic. It would never be part of the right answer choice in a real GMAT question. The other answer choice you mentioned, however, isn't right, because there needs to be an "as" after "effective". By the way, coul...

Hi Saurabh - Consider this sentence: Elizabeth was given a book by Ernest Hemingway. The sentence is unclear, because it could mean (1) "Ernest Hemingway gave Elizabeth a book." (not necessarily a book that Hemingway himself had written). or (2) "Somebody gave Elizabeth a book written...

Let x be the number of shirts sold, and let y be the number of sweaters sold. The question can be rephrased as "Is y>x?". The question also tells us the prices of the shirts and sweaters, so we know that the average price of all the shirts and sweaters that the store sold during the sal...

Manhattan GMAT has just released new, revised versions of our textbooks (May 2007). The new books contain greatly expanded coverage of Critical Reasoning and Reading Comprehension. There is now a whole book for Critical Reasoning and a whole separate book for Reading Comprehension (these two topics ...

Hi there,

The Study Tracker is referring to the 2007 edition of the textbooks. These were released in May, after your class began.

By and large, you can take references to the Reading Comprehension book to mean references to the Reading Comp section of the book that you own.

Nice job, Saurabh. Here are a couple of links that illustrate Saurabh's point about angles in a polygon:

Hi Saurabh, To figure out whether a verb agrees in number (i.e. singular vs. plural) with its subject, you first have to find the subject. The subject of the verb is or are the person(s) or thing(s) doing the action of the verb. What is the subject of the verb "derive" in the following phr...

That's right, yamini - the difference between "can" and "could" is essentially the same as that between "will" and "would".

Let's think about how we know that triangles ACD and BCA are similar. 1) Let's say that <CDA is x degrees, and <DAC is y degrees. Since <ACD is 90 degrees, and the sum of all the interior angles in a triangle is 180, we know that x + y =90 . 2) Now let's look at <BAC. We know that <BA...

Scores on our practice tests match pretty closely with those on real tests, based on the data we've collected from former students. (For more on this, see Andrew Yang's explanation from April 10 - http://www.manhattangmat.com/forums/scoring-accuracy-t90.html - but note that due to recent improvement...

Yeah, I hope you do great
