Options:
(A) n is a perfect square
(B) n is an odd number
(C) n is an even number
(D) n is a perfect cube
(E) none
a: Stream of consciousness: For example, if there were 4 carrot rows, the garden would have a 4x4 arrangement. If each carrot attracts 4 bunnies, the number of bunnies would be (4*4)*4 = 64 pieces, which is a cube of 4. The answer is (D).

Options:
(A) 3x
(B) 4x
(C) 5x
(D) 12x
(E) 27x

Options:
(A) 888
(B) 333
(C) 555
(D) 1221
(E) 889
answer: Stream of consciousness: Given Exp. = (a3 + b3) = (a + b) = (666 + 555) = 1221(a2 - ab + b2) The answer is (D).
