TASK DEFINITION: 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.
PROBLEM: passage: The Grand Canyon of northern Arizona in the United States, with an average depth of 1,600 m (one mile) and a volume of 4.17 trillion cubic metres, is one of the world's largest canyons. It was among the 28 finalists of the New7Wonders of Nature worldwide poll. (Some referred to it as one of the 7 natural wonders of the world.) Copper Canyon in Chihuahua, Mexico is deeper and longer than the Grand Canyon.
 question: is the grand canyon the biggest canyon in the world?

SOLUTION: No

PROBLEM: passage: To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ``dairy bull'' or a ``beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.
 question: do cows need to give birth to produce milk?

SOLUTION: Yes

PROBLEM: passage: Bert and Ernie live together in an apartment in the basement of 123 Sesame Street. Despite sleeping in separate beds, they share the same bedroom, which has led to some speculation that they are a representation of gay lovers. This is denied by Sesame Workshop, and some of Bert's interactions with female characters appear to show that he is attracted to women: serenading Connie Stevens in the Some Enchanted Evening segment of a first-season episode of The Muppet Show, and recording a song about his girlfriend, I Want to Hold Your Ear, which was released on several albums.
 question: did ernie and bert sleep in the same bed?

SOLUTION:
No
