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.
One example is below.
Q: If k is an integer and \(k = \frac { m } { 3 } \) which of the following must be true? I. m is an even number. II. m is a multiple of 3. III. m is an odd number.
(A)I only (B)II only (C)III only (D)I and II only (E)I, II, and III
A: B
Rationale: m isn’t necessarily an even or odd number so A,D,E,C are incorrect. for frac { m } { 3 } to be an integer m must be a multiple of 3. 
Q: If \(a + 2 > 5\) and \(a - 4 < 1\), which of the following could be a value for a?
(A)2 (B)3 (C)4 (D)5 (E)6
A:
C
