The argument states that work of scientists need not be officially confirmed and in the following lines supports/strengthens the statement. if we can provide one valid reason why the work of scientists has to be officially confirmed, then the argument will be weakened. A)If experiments take a lot of years to replicate(say 10 years) and after 10 yrs a work is said to be wrong,then it doenst seem rightt(My Valid Reason) B)This strengthens the argument C)Totally out of scope. D)Irrelevant E)This partiallly strengthens the argument.

This passage is picked from the SETS and i find this passage difficult to comprehend. I answered the 3rd and 4th questions right on the first reading itself. But, to answer the 1st and 2nd questions i had to read the passage thrice and and at a pace slower than my usualpace. Can someone who has taken the test please tell me, if this is the level of difficult of the passages tested in GMAT or do i need more practice?? Also,please tell me where i can get these kinds of passages, if i have to improve on my comprehension. I read on other forums that RC99 is very good and has passages at GMAT level. Is that true? Some one please guide me. In most of my CATs i am loosing in RCs. Thanks in Advance!!

If X and Y are integers and X>0, Is Y>0? (1)7X-2Y>0 (2)-Y OA is given as E. Please critique my explanation.Also let me know if this is the best way to solve. Consider statement (1); 7X > 2Y -->Y0, Y Consider statement (2); Given X>-Y and we know that X is an integer greater than 0. Min. value X can take is 1 So,1>-Y --> Y>-1 which means that Y can be zero and greater than zero. Hence Insuff. conbining (1) and (2) it is still insufficient.(Ans E)

1)If (Y+3)(Y-1)-(Y-2)(Y-1)=R(Y-1), what is the value of Y? (1) R^2=25 (2) R=5 Can someone explain how to solve this. I tried solving it and i see that we dont need any of the statements to get the value of R. Even after knowing the value of R,we cannot sove for Y.What do we call these type of equations?

Depending on which scholar you consult,either daniel defoe's Robinson crusoe,Henry fielding's Joseph Andrews or Samuel Richardson's Pamela is believed to have been the first English novel ever written. a)is believed to have been the first English novel ever written. b)is believed as being the first English novel ever written. c)are the English novels believed to be the first written. d)are the English novels which were believed as the first written. e)are the first English novels ever believed to be written. Please pour in your thoughts whether "is" is to be used or "are" is to be used.

IMO the answer is B.

Can some one please explain this problem in more detail?

Let there be a total of 100 Litres of the solution. which contains 1 part as substance and 99 parts water. Let a parts of water is evaporated, then the resulting solution has (100-a) litres of water. Now (99% of 100) - a =98% (100-a) --> 99 - a = 98 - 98a --> 1 = 2a -->a=50 i-e 50 parts of the initial total amount(100) is evaporated or 50 parts of initial water content(99)=50.5 is evaporated.

The OA is given as D

If a and b are positive integers such that a – b and a/b are both even integers, which of the following must be an odd integer? A. a/2 B. b/2 C. (a+b)/2 D. (a+2)/2 E. (b+2)/2

What is the value of │x + 7│? (1) │x + 3│= 14 (2) (x + 2)^2 = 169 Can someone explain how to solve this.

If k, m, and p are integers, is k – m – p odd? (1) k and m are even and p is odd. (2) k, m, and p are consecutive integers. The official answer for this is given as A. But how can we solve this question using A. Given k,m,p are integers. if i take k=2,m=4 and p=1 then i get k-m-p=(2-4-1) = -3. Is the OA wrong or is -3 odd??

hi MBAChase i was also confused looking at the diagram. From the diagram it seems like the question is asking for angle BCD and i did'nt get how to find BCD. Is there a way to solve for BCD

The official answer is D and the source of this question is SETS
