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: Citric acid can be added to ice cream as an emulsifying agent to keep fats from separating, to caramel to prevent sucrose crystallization, or in recipes in place of fresh lemon juice. Citric acid is used with sodium bicarbonate in a wide range of effervescent formulae, both for ingestion (e.g., powders and tablets) and for personal care (e.g., bath salts, bath bombs, and cleaning of grease). Citric acid sold in a dry powdered form is commonly sold in markets and groceries as ``sour salt'', due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed.
 question: can lemon juice be used as citric acid?
[EX A]: Yes

[EX Q]: passage: In the United States, the dish is most commonly sold as ``fish and chips'', except in Upstate New York and Wisconsin and other parts of the Northeast and Upper Midwest, where this dish would be called a fish fry. Despite the name ``fish and chips'', and the US meaning of ``chips'', the dish is served with French fries (much thinner than British and Irish chips). In the Southern United States, a common form of cuisine is fried catfish with French fries, accompanied by coleslaw, pickles, raw onion slices and lemon slices.
 question: do they have fish and chip shops in america?
[EX A]: Yes

[EX Q]: 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?
[EX A]:
Yes
