You are given a mathematical question described with an open-ended vocabulary. Questions in this task involve real-world situations, describing a mathematical problem. You are also given 4 or 5 answer options (associated with "A", "B", "C", "D", "E"). Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D', 'E'. LaTeX mathematical format (the standard way to express mathematical expressions in the typesetting software known as LaTeX) is used to express equations. Each question is solvable with high school math knowledge. Give only one answer for each question.

Example Input: The number of turtles in Mosquito Pond has doubled every three years since the pond was discovered. The number of turtles in the pond can be described as \(n = (x)2^{\frac{t}{3}}\), where t is the number of years since the pond was discovered, n is the number of turtles in the pond at time t, and x is the number of turtles in the pond when it was discovered. If there were 160 turtles in Mosquito Pond nine years after it was discovered, then how many turtles lived in the pond the year it was discovered?
(A)2 (B)10 (C)20 (D)40 (E)160
Example Output: C

Example Input: If Donald can type \(w\) words in m minutes, which of the following represents his average typing speed, in words per minute?
(A)\(\frac { m } { w } \) (B)\(\frac { w } { m } \) (C)\(\frac { 1 } { 2 } mw\) (D)\(mw\) (E)\(2mw\)
Example Output: B

Example Input: There are y sculptures in a gallery. If one is to be selected at random from the collection, the probability that a bronze statue will be selected is \(\frac { 2 } { 5 } \). In terms of \(y\), how many of the sculptures are bronze statues?
(A)\(\frac { y } { 5 } \) (B)\(\frac { 2y } { 5 } \) (C)\(\frac { 5y } { 2 } \) (D)\(\frac { 7y } { 5 } \) (E)\(5y\)
Example Output:
B
