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.

[Q]: 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.
[A]: C


[Q]: A train takes one hour longer to travel d miles at its normal speed than it would if it were traveling 10 miles faster. Which of following equations could represent the equation to find the train's normal speed \(s\), in miles per hour?
(A)\(\frac { d } { s + 10 } = s + 1\) (B)\(\frac { d } { s } = \frac { d } { s + 1 } \) (C)\(\frac { s } { s + 10 } = d\) (D)\(\frac { d } { s + 10 } - \frac { d } { s } = 1\) (E)\(\frac { d } { s } - \frac { d } { s + 10 } = 1\)
[A]: E


[Q]: For the annual school fundraiser, Santiago has \(p\) pledges each for \(c\) cents per lap that he jogs. If his school track has 4 laps per mile and Santiago raises a total of \(d\) dollars, how many miles did he jog in terms of \(p\), \(c\), and \(d\) ?
(A)\(\frac { 25d } { pc } \) (B)\(\frac { 4pc } { d } \) (C)\(\frac { 100d } { pc } \) (D)\(4pcd\) (E)\(25pcd\)
[A]:
A
