E. From 1 --> y = x + 3 so PR>PQ but no info on the third side. Insuff From 2 --> PQ = 4 , PR= y, again not enough to find which side is the greatest. Combining, PQ= 4, PR= 5. Third side can be anywhere between 5-4 (1) and 9(5+9) If the third side, QR is 1,2 or 3 angle opposite PR is the largest. If QR is 6,7 or 8, angle opposite QR is largest. SO E

gmat168, it would be very helpful if you can post your first impressions of the new OG guide. Mainly, if OG11 has mostly old questions in ETS paper tests as Erin fears. I have decided to go with OG10(only for verbal practice) and 11 as the new supplements seem to overlap with OG10. I'll focus on all sections in OG11 while using OG10 mainly for verbal. Does this strategy sound ok ?

I vote for B : If some fullerenes has been found on the remains of the small meteorite, then it may not be useful to geologists in evaluating the state of the earth's crust.

Now that OG 11th edition is out, I am sure many gmat takers(those who have about a month or two before the gmat) will be debating what combination of books would be the most optimal . It looks like all questions(300 each in Q and V) in the two supplements are from OG 10. So does one need to get OG 11 and OG10 or would OG 10 be good enuf. If you see the posts of all folks who did 700+, everyone of them managed with OG10.

That's a very good question. I am faced with the same dilemna. If the supplements have the same questions as the 10th edition, then it may not be of much value. OG11 plus OG10 may be an overkill as well..

Why not C for "and it is believed to have been" ? "it" refers to the reptile.

B it is. Premise1: If a language center of the brain is damaged(X), then linguistic capabilities are impaired in some way(Y). So, If X then Y, implies : If not Y then not X. Conclusion : People have suffered a serious stroke on the left side of the brain and their linguistic capabilities are NOT impaired. They must have their language centers in the right half. So not Y means Not X: which is same as B Also wakau, can you please use spoiler tags ?

16. A number of linguists contend that all of the thousands of languages spoken by the world’s five billion people can be traced back to a common root language. (A) that all of the thousands of languages spoken by the world’s five billion people can be traced (B) that the world’s five billion people speak thousands of languages of which all can be traced © the world’s five billion people speak thousands of languages which are all traceable (D) all of the thousands of languages spoken by the world’s five billion people to be traceable (E) the ability to trace all of the thousands of languages that are spoken by the world’s five billion people OA: Not sure I agree with the OA. What is wrong with B ?

check out spidey's notes. "due to" should be used only when it can be replaced by "because of". so the answer is E.

I would pick E. I the argument is weakened if there are cases where a) an instiutution has not acted responsibly and still retained power b). an institution has acted responsibilty and still lost power OR E is an example of scenario a.

I would go with E. Writers ---> Stalin's cruelty (in his last days) was explained by "morbid suspiciousness". Critic ---> "morbid suspiciousness is an inherent trait of all tyrants. So politically he had to be cruel.

Folks, I took PP1 and got 660 with only a 32 in verbal. I immediately knew after the test that I need to work on RC. Had to guess the last 2-3 questions to complete. Looks like RC can be improved with practice.. If there are any specific tips, it would greatly help..

Folks, Have a question about expected score. So far : 690 in Kap diag 600 Kap CAT1 Just took PP1 today and got 660 (Q48 V32) (Not yet started OG) A bit disappointed with PP1 score. Do you think I can cross 700 if I do the OG thoroughly from this poit on..Appreciate your feedback.

NEw Perimeter = 2(1.1l + 0.9b) Old 2(l + b) Difference = 0.1(l -b) This could be or == So 4

My take on this : combining aba =a --- (1) bab = b ---(2) multiplying both sides of (1) and (2) (ab)^3 = ab So, if x^3 = x, then x = 1 or -1 ab = 1 or -1, insuff. That's why the answer is E.
