IMO E. With the number of demand for college graduates not increasing, the only thing that explains the increase in the salary difference is that the demand for high school diploma holders have increased.

E. The problem of unclear referrant is solved by this option.

IMO B. If B is not assumed, then Japanese and European countries will not try to take advantage of falling dollar and hence US exports of pulp will not increase.

Hey Guys, Can some one explain why A is the correct answer?

OA is B. Thx guys.

1) Answer A. y= n^3 /450. This may be an integer or a fraction. If you further divide y by an integer, chances are less that the quotient will be a integer. In other words, you cant be certain whether y divided by an integer will be an integer or not. 2) Answer E. M = 4^(1/2) + 4^(1/3) + 4^(1/4) = 2 + 1.5 + 1.4 Here, as 4^1/4 = 2 ^1/2= 1.41 and 4^1/3 comes greater than 1.5 3) Answer C. Both the statements together are sufficient. For y=3x + 2 to contain the point (r,s), it should satisfy s= 3r + 2 or 3r-s +2 =0 from A) we cant be certain that (3r + 2 - s) is 0 as 4r + 9 -s can also be 0. Hence this statement is insufficient. Same problem with B). Together we can definitely say that 3r + 2 - s =0. Hence both the statements together are required.

A particular skin rash has been linked to exposure to certain types of high-intensity tanning beds. While not dangerous, these rashes are painful and often unsightly, at least in the eyes of those who contract them. Over 90% of females ages 24-30 who use a particular tanning bed called ‘The Bronzer’ have contracted the rash at varying levels of severity. Although using ‘The Bronzer’ does not always lead to a contraction of the rash, the only way to completely avoid the rash is to refrain from using ‘The Bronzer’ and other tanning beds altogether.Which of the following indicates a flaw in the author’s reasoning? A. It relies on evidence about a specific product to make a recommendation about an entire class of products. B. It assumes that one possible cause of a condition is the only cause of that condition. C. It assumes to be true what it sets out to prove. D. It makes a generalization based on one segment of the population. E. It contradicts itself by proclaiming a condition to be not dangerous and then offering a recommendation to avoid that condition. One of my friends passed this question. I am confused between A and B. Please discuss.

Great score man.. Congrats!!

Congrats mate. Really great score.

1) Cube of fractions is less than number itself. As x is positive, we can say x^3> x, and hence x is a fraction i.e. less than 1. Sufficient. 2) Again, as x is positive we can divide by x giving x^2> x which will be true for positive fractions. Sufficient. Both are sufficient, hence D.

Congrats!! Great score.. Cheers, FeverGMAT

1) Insufficient. You can't determine with just the number of pencils. 2) Can be sufficient or insufficient. Just check how multiples of 23 and 21 sums upto 130. 21*6 =122 21*5 + 23*1=128 21*4 + 23*2 =130. So 2 pencils of 23 cents. No other combination of multiples of 21 and 23 will be possible as 21 and 23 are co-prime. So B is sufficient. Hence the answer.

This is a case of circular reasoning. According to senator, no true art is obscene. And to justify this, he says that if work of art is obscene, then it is not true art. Answer should be D.

Hey charry_008, 'not so..as' is a correct idiom in GMAT. There is one question based on this idiom in OG11. Also, 'so X that Y' and 'as X as Y' are correct. Dont think that 'so X as Y' is correct.

OA is option C.
