we are between "anyone distant" (A) and "related distantly" © I can't feel what is more implied here...

Again D A and B implies that the fact of importance assists flies, whereas hydrocarbons do C is wrong due to misplacement of which E compares "their own species" and "others" rather than other species

Hard Bin :hmm: 650+ or 700+ or 750+ could you please be more specific if it is possible :)

Is my logic really so far from the truth?? I still have question: Q1 Is trying numbers (5, 3 and 2) the easiest solution for this question? And may be for all questions with remainders? gschmilinsky, thanks a lot for such questions Bob, Manish, thanks for explanations I wonder from which score bin these questions should be? Any ideas?

Good questions, I'm trying... 1) rephrase: x/a = (x-b)/a + b/a and x/b = (x-a+2)/b + (a-2)/b this gives us at least that x-b is divisible by and x-a+2 is divisible by b trying answers: E and D give nothing being substitued in either of equations C and B could be tested only in the first equation So A is left (not sure) 2) x-y should be greater than x+y, could be true if y is negative only, so B 3) If we deal with positive numerator and denominator and add the same number to each of them the value of the fraction will always decrease - we divide on greater number both parts of a new numerator (2 is sufficient, answer is no). If a fraction is less than 1, by adding the same number the new fraction will always be greater than original (1 is sufficient, answer yes). So D. 4) The inequality is true only if y 5. (1) is insufficient, because for x+y to be greater than 0 both can be greater or smaller one another. (2) is insufficient too, y^x is less 0, only when y is negative and x is odd. So inequality is true for x,y being either 3,-2 or -3, -2. Answer is E.

This formula I guess could not be given in the text of question ) Q1: 21*(21-3)/2=189 diagonals has a 21-sided polygon. It also has 21 vertices, and from each vertice (n-1)=20 lines can go to other vertices being adjacent sides (2) and diagonals (the rest 18). So we should have 189-18=171 diagonals left. Who knows why the answer is 170?? Q2: 18*(18-3)/2=135, so from each vertice 15 diaginals go, and 45 from three vertices. Answer is 90.

Let's simplify to (1) X/(Y+1) (2) X/(Y-1) For the (1) X For the (2) X Go for B.

Vote for B Key word is geographical. If we establish that any geographcal varialtions are unrelated to a relative number of certain deseases in different areas, it would be clear that comparable number of medical cases should require comparable number of appropriate treatments.

IMO there should be a mistake in the OA. Answer A explains nothing. My choice is B despite it's a bit tricky. If it were telling that population decreased everything would be at the right place with the per capita expenditures: numerator stands still, denominator declines, result goes up. Since B says that population grows the logic should be that constant use here means also use per capita, not an absolute value. So prices are frozen, quantity increases (but per person doesn't change) and population increases. This could result in increase of expenditure per person.

Bob, the source is this http://www.www.urch.com/forums/gmat/560-full-length-gmat-test-3-a.html and I still have some doubt whether to consider answers absolutely right. That "too many correct answers" seems to be the greatest trick of this question. If to go with the shortest or the least awkward the choice would be between A and B. The source I cited says that A is correct. But this contradicts the sequence of tenses rule, which requres past be followed by past.

The nurse told me that the doctor's office closes at 5:00 pm (A) The nurse told me that the doctor's office closes at 5:00 pm (B) The nurse told me that the doctor's office closed at 5:00 pm © The nurse had told me that the doctor's office had closed at 5:00 pm (D) The nurse told me that the doctor office closes at 5:00 pm (E) The nurse told me that the doctor's office would have to close at 5:00 pm

Very very useful stuff. I only wonder where it comes from for the reason of whether the answers are absolutely correct. Nivolet, many thanks for explanations of Q18. For me still unclear are V24 (sequence of tenses) V36 (?) and Q21 (seems so simple, but what's the trick?). Can somebody explain?

1) A - see no flaws, until recently is correct, led is in the past 2) A - efficiency in and B is not parallel with although 3) D - bag inflated whereas a burst would appear and make

IMO all meanings of thus clearly says that it is an adverb. But E assumes an adjective in this place. That's why D wins despite "although".

Vote for C
