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: Eva and Magnus took a road trip and shared the driving. Eva drove four times as many miles as Magnus drove. What percent of the total miles of the trip did Eva drive?
(A)70\% (B)75\% (C)80\% (D)85\% (E)90\%
Example Output: C

Example Input: A certain pie is made by baking the crust for 7 to 10 minutes, adding the filling, and baking the entire pie for another 15 to 18 minutes. What are the minimum and maximum total baking times for this pie?
(A)7 minutes and 10 minutes (B)10 minutes and 18 minutes (C)15 minutes and 18 minutes (D)22 minutes and 25 minutes (E)22 minutes and 28 minutes
Example Output: E

Example Input: The value of 10 pounds of gold is \(d\) dollars and a pound of gold has the same value as \(p\) pounds of silver. what is the value in dollars, of one pound of silver?
(A)\(\frac { \sqrt { d } } { 10p } \) (B)\(\frac { \sqrt { 10p } } { d } \) (C)\(\frac { \sqrt { dp } } { 10 } \) (D)\(\frac { \sqrt { p } } { 10d } \) (E)\(\frac { \sqrt { 10d } } { p } \)
Example Output:
A
