Thank you.

Looking for a quick method. Thanks.

I felt as if a SUBJECT were missing in C's AS clause. I, therefore, chose A. Moreover, I thought it was better to make an empty-IT explicit in the sentence to make it parallel to an existing cleft-IT at the tail-end of the sentence.

Please help to eliminate A As it is with traditional pharmacies, on-line drugstores rely on prescriptions to be successful, since it is primarily prescriptions that attract customers, who then also buy other health related items. a) c) As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on-line drugstore

1) Arrange white balls first. _W_W_W_W_W_W_W_ Out of possible 8 spots, chose 5 for blacks = 8c5=56 2) arrange 4 men in a circle in 3! ways, then arrange 4 women in between them in 4! ways. Total ways = 3! * 4! = 144 3) choose at least one W = (2^3)-1.......a choose at least one S = (2^4)-1.......b choose at least one FJ = (2^5)-1.......c Total ways = a*b*c = 3255

Appreciate your elaborate response gschmilinsky. Just wondering, putting a semi-colon in E won't leave the WHEN adverb clause hanging? (I mean, it will be without any independent clause)

3 D's can be selected from 10 D's in 10c3 ways. Similarly 3 R's can be selected from 10 R's in 10c3 ways. Ans : 10c3*10c3...(b)

Please advice what to look for, in this SC? Some patients who do not respond to therapies for depression may simply have received inadequate treatment, having, for example, been prescribed a drug at a dosage too low to be effective or having been taken off a drug too soon. a) b) having, for example, a drug prescription that was ineffective because the dosage was too low, or being c) as, for example, having too low of a dosage of a prescribed drug for it to be effective, or being d) when they have, for example, been prescribed too low a dosage to be effective, or were e) for example, when they have a drug prescription with a dosage too low to be effective, or been

Using 5 colors, we can paint in (2^5)-1 ways Using 6 colors, we can paint in (2^6)-1 I think, it would be 31/63

Many thanks Chix.........I liked your logic.

3 positive integers are selected at random from 9 consecutive positive integers. What is the probability that their average is also an integer. a) 9/28 b) 1/28 c) 1/3 d) 5/14 e) 9/29

Is range of a non-empty set S bigger than its mean? 1) All members of S are negative. 2) The median of set S is negative. I am sorry, I don't have an OA.

Others have more serious errros - subject-verb in B,C and D - pronoun in D and E

I have a very general question. Does ETS view present perfect as continuing in the present time? I found some OG explanations contradictory. OG 90) Since 1986, several corporations have begun paying their investment advisers a small basic fee. The present perfect have begun conveys continuity OG 55) Many doctors have elected to retire early rather than face the threats of lawsuits. Have elected describes a situation that continues in the present OG 88) The Emperor Augustus, it appears, commissioned an idealized sculpture portrait, the features of which are so unrealistic that they have constituted what one scholar calls an "artificial face." present perfect suggests that the statue's features once constituted an artificial face but no longer do so. 77 e) Though the term "graphic design" may have suggested corporate brochure and annual report layout, it has signified……….. Have suggested indicates recently completed action.
