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: If it is now 1:15, what time will it be when the hour hand has moved through an angle of \(10\degree\)?
(A)1:25 (B)1:35 (C)2:15 (D)3:15 (E)11:15
Example Output: B

Example Input: Anne-Marie was \(x\) years old \(y\) years ago. How old will she be in \(z\) years?
(A)\(x + y + z\) (B)\(x - y + z\) (C)\(z - x - y\) (D)\(y - x + z\) (E)\(x - y - z\)
Example Output: A

Example Input: Brigitte's average (arithmetic mean) on her six math tests this marking period is 75. Fortunately for Brigitte, her teacher drops each student's lowest grade, thus raising Brigitte's average to 85. What was her lowest grade?
