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: Sam's locker combination consists of three two-digit numbers. The combination satisfies the three conditions below. One number is even. One number is a multiple of 3. One number is the day of the month on which school started. If each number satisfies exactly one of the conditions, which of the following could be the locker combination?
(A)\(10-23-15\) (B)\(24-18-13\) (C)\(12-20-26\) (D)\(15-21-26\) (E)\(34-30-21\)
Example Output: A

Example Input: A train takes one hour longer to travel d miles at its normal speed than it would if it were traveling 10 miles faster. Which of following equations could represent the equation to find the train's normal speed \(s\), in miles per hour?
(A)\(\frac { d } { s + 10 } = s + 1\) (B)\(\frac { d } { s } = \frac { d } { s + 1 } \) (C)\(\frac { s } { s + 10 } = d\) (D)\(\frac { d } { s + 10 } - \frac { d } { s } = 1\) (E)\(\frac { d } { s } - \frac { d } { s + 10 } = 1\)
Example Output: E

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
