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.

[EX 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?
[EX A]: Yes

[EX Q]: passage: A more recent addition to the football helmet is the visor or eye shield, which is affixed to the face mask to protect players from glare or eye injuries, such as pokes. It is believed that the first player to use a protective visor Mark Mullaney of the NFL's Minnesota Vikings in 1984, in order to protect a healing eye injury. Top manufacturers of visors are Nike, Oakley, and Under Armour, with Leader being the first to come out with a visor/shield for former Chicago Bears quarterback Jim McMahon (who needed the visor because of a childhood eye injury). While Mullaney and McMahon's visors were tinted, most of the earlier visors were clear or smoked, but they are now offered in a variety of styles ranging from blue, gold, black, rainbow, silver, or amber. High-school and pee-wee leagues prohibit all but clear visors. This rule was enacted so that training staff and coaches can easily view a player's face and eyes in the case of a serious injury, to discern if the player is conscious. The NCAA banned the use of tinted visors for the same reason, and the NFL has followed suit as well. However, players with eye problems may still obtain special permission to wear tinted visors, some notable examples being LaDainian Tomlinson and Chris Canty.
 question: can you wear colored visors in college football?
[EX A]: No
