In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.

[Q]: passage: The touch-move rule in chess specifies that, if a player deliberately touches a piece on the board when it is his turn to move, then he must move or capture that piece if it is legal to do so. If it is the player's piece that was touched, it must be moved if he has a legal move. If the opponent's piece was touched, it must be captured if it can be captured with a legal move. This is a rule of chess that is enforced in all games played in formal over-the-board competitions. The player claiming a touch-move violation must do so before making a move.
 question: do you have to move a piece if you touch it in chess?
[A]: Yes


[Q]: passage: In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate x is x − 4x + 7. An example in three variables is x + 2xyz − yz + 1.
 question: does a polynomial have to have a variable?
[A]: Yes


[Q]: passage: In mathematics, a divisor of an integer n (\displaystyle n) , also called a factor of n (\displaystyle n) , is an integer m (\displaystyle m) that may be multiplied by some integer to produce n (\displaystyle n) . In this case, one also says that n (\displaystyle n) is a multiple of m . (\displaystyle m.) An integer n (\displaystyle n) is divisible by another integer m (\displaystyle m) if m (\displaystyle m) is a divisor of n (\displaystyle n) ; this implies dividing n (\displaystyle n) by m (\displaystyle m) leaves no remainder.
 question: is a divisor the same as a factor?
[A]:
Yes
