Here's Why:
7 g) X3 }; N+ t& E6 A/ @# UThe error in this sentence occurs at (A), where there is subject-verb disagreement. The singular verb "is" does not agree with the plural subject " Ballet, modern dance, and Indian classical dance." The plural verb"are" should be used instead. In addition, the singular noun "form" should be changed to the plural noun "forms."

/ t7 v9 y" B, Z. t& v5 O4 t! E

6 X2 `5 l! U& v# m. K- a0 oThere are two right triangles in the figure. One triangle is formed by part of the line from the sun to point P, the perpendicular from the top of the fence post to the ground, and the fence post's shadow along the ground. Since these two right triangles share the acute angle at P, they are similar triangles. Since the corresponding sides of similar triangles are in proportion, it follows that 180/x=60/t. Solving this equation for x, the height, in centimeters, of the fence post, yields x=3t.

Answer: C
0 W  U2 h3 r# W: ]/ oHere's Why: Choice (C) is correct. The mayor was confident about her campaign, so it makes sense to suggest that she felt her political platform would "prevail," or triumph. The phrase "less... than" indicates that as a result of her confidence, the mayor found her opponent's popularity to be less than a threat; she considered it a mere "distraction."

" d2 K8 {1 x# \5 e( N( N
Answer:D
Here's Why:
# ^' w0 Y5 a- ^Choice (D) is correct. The structure of the sentence suggests that Livingstone's reputation is based on two different , even mutually exclusive, interpretations; in other words, these views of him are "dichotomous." The second part of the sentence describes this dichotomy:some historians "revile" him, while others do the opposite, or "praise" him.

9 C9 o) n0 ~9 T
Answer: E
! c; S0 ]+ a3 G- F7 \; D! oHere's Why:
* l) W& h$ v) e6 JIf a formula gives the nth term of the sequence for all positive integers n, it must give the nth term of the sequence for n=1,2,3, and 4. If n=1, then 2n=2 and n^2+1=2, but the first term of the sequence is 3, so the general formula cannot be 2n or n^2+1. Also, if n=3, then 2n+1=7 and 3n=9, but the third term of the sequence is 11, so the general formula cannot be 2n+1 or 3n. However, for n=1,2,3, and 4, the values of n^2+2 are 3,6,11, and 18, receptively. Therefore, the general formula for this sequence could be n^2+2.
