GMAT

There are five main types of GMAT questions:

Quantitative Comparison
Problem Solving
Sentence Correction
Critical Reasoning
Reading Comprehension


GMAT Quantitative Comparison Question

In these questions you have to determine if the statements contain the necessary information to answer the questions.


Is x > 4?

1) x  < 9

2) x is an integer


A) if statement (1) by itself is sufficient to answer the question, but statement (2) by itself is not;

B) if statement (2) by itself is sufficient to answer the question, but statement (1) by itself is not;

C) if statements (1) and (2) taken together are sufficient to answer the question, even though neither
statement by itself is sufficient;

D) If either statement by itself is sufficient to answer the question;

E) If statements (1) and (2) taken together are not sufficient to answer the question, requiring more data pertaining to the problem.


Solution
Statement (1) implies that x is in between +/- 3 (+/- means positive or negative). Both +3 and -3 are less than 4, so the answer is "NO" (x  < 9) and (1) is sufficient, that is NO, x is not greater than 4.

A "NO" answer is equally acceptable as a "YES" answer. It is only necessary that there is sufficient information to answer the question. (2) does not provide any necessary information. The correct response is A, since statement (1) does provide enough information.



Critical Reasoning questions have you analyze the reasoning in an argument and determine if it is valid or analyze its implications.


The widespread use of antibiotics has two negative effects. Antibiotics use can produce antibiotic-resistant strains because the small numbers of bacteria that aren't killed by the antibiotic are the ones that survive and breed. In addition, antibiotics can kill the body's natural microbes that help fight off foreign bacteria.

Which of the following practices can help reduce these negative consequences and benefit patients?

A) Using antibiotics derived from natural products
B) Produce stronger antibiotics
C) Steadily increase dosage if the results begin to decline
D) Do not give the antibiotic to all people who are sick
E) Changing the antibiotics used every few weeks


Choice (E) gives a way of counteracting a serious drawback of the sustained massive use of antibiotics. If you rotate the antibiotics, the bacteria that develop a resistance to one bacterium will then be killed by the next antibiotic. Choice (A) would not necessarily make any difference. Steadily increasing dosage or developing stronger dosages will not kill the bacteria that have developed a resistance, so choice (B) and (C) can be ruled out. (D) Not treating patients will not benefit patients.


GMAT Sentence Correction

1. Satisfied by the strong performance on GMAT test, it was decided by Peter to give himself a two-week rest.

A.      it was decided by Peter to give himself a two-week rest

B.      Peter decided to give himself a two-week rest

C.      a two-week rest was given by Peter to himself

D.      Peter's decision was to give himself a two-week rest

E.      it was decided that Peter give himself a two-week rest

The correct answer is B because it is Peter who was satisfied. In choice B, Peter appears as the subject. Choices A, C, D and E are incorrect because they used it, a two-week rest, Peter's decision, and it as the sentence subject. In fact, the participial phrase beginning with satisfied should modify the subject of the main clause in order to follow the grammar rule.



2. Since 1999, the number of internet websites with the domain name ending with .com have grown from 62 million to nearly 78 million.

A.      have grown from 62 million to nearly 78 million

B.      are growing from 62 million to nearly 78 million

C.      grew from 62 million to nearly 78 million

D.      grow from 62 million to nearly 78 million

E.      has grown from 62 million to nearly 78 million


E is the correct answer. In choice A, the plural verb have does not agree with the singular subject number. Choices B and D commits the same fallacy by using plural verbal phrase are growing and grow respectively. B, C, and D also misused the verbal tense which should be present perfect.
