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: Nora has 10 fewer than twice the number of CDs that Deborah has. If n represents the number of Nora's CDs, and d represents the number of Deborah's CDs, which of the following is a correct equation relating n and d ?
(A)\(n = 2d - 10\) (B)\(n = 2(d - 10)\) (C)\(n = 10 - 2d\) (D)\(n = 2(10 - d)\) (E)\(n = 10 - (d +2)\)
Example Output: A

Example Input: So far this year, Adam has played 30 games of chess and has won only 6 of them. What is the minimum number of additional games he must play, given that he is sure to lose at least one-third of them, so that for the year he will have won more games than he lost?
(A)25 (B)34 (C)57 (D)87 (E)It is not possible for Adam to do this.
Example Output: C

Example Input: In a certain game, different colored tokens are worth different numbers of points. A blue token and a red token together are worth a total of 12 points, a blue token and a green token together are worth a total of 13 points, and a red token and a green token together are worth a total of 15 points. How many points is a blue token worth?
(A)5 points (B)6 points (C)7 points (D)8 points (E)9 points
Example Output:
A
