You are given a mathematical question described with a circumscribed mathematical vocabulary. Questions in this task usually contain some variables (e.g. X, Y), equations (e.g. X+Y=3) and some relationships (X is greater than Y). Often you need to find the value of the variable using equations and relationships. 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.

Input: Consider Input: If \(\frac { a - b - 5 } { 2 } = 10\), then what is the value of \(a - b\) ?
(A)20 (B)25 (C)30 (D)35 (E)40

Output: B


Input: Consider Input: \(ts < 0 < t - s\) If the statement above is true, which of the following must also be true?
(A)\(t > s\) (B)\(s > t\) (C)\(t = s\) (D)\(t > 0\) and \(s > 0\) (E)\(t < 0\) and \(s < 0\)

Output: A


Input: Consider Input: \begin{gather*} 4, -4, -1, ... \end{gather*} The first term in the sequence above is 4. Each even-numbered term is found by multiplying the previous term by \(-1\); each odd-numbered term is found by adding 3 to the previous term. For example, the second term is \(4 \times - 1 = -4\), and the third term is \(-4 + 3 = -1\). What is the 37th term of the sequence?
(A)\(-4\) (B)\(-1\) (C)0 (D)1 (E)4


Output: E
