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 primitive Liphistiidae, the ''trapdoor spiders'' of the family Ctenizidae and many tarantulas are ambush predators that lurk in burrows, often closed by trapdoors and often surrounded by networks of silk threads that alert these spiders to the presence of prey. Other ambush predators do without such aids, including many crab spiders, and a few species that prey on bees, which see ultraviolet, can adjust their ultraviolet reflectance to match the flowers in which they are lurking. Wolf spiders, jumping spiders, fishing spiders and some crab spiders capture prey by chasing it, and rely mainly on vision to locate prey.
question: is there such a thing as a crab spider?

SOLUTION: Yes

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: Ireland has finished first seven times, more than any other country, Ireland also won the contest for three consecutive years (1992, 1993, 1994), more consecutive years than any other country. Three countries have won twice in a row, Spain (1968 and 1969), Luxembourg (1972 and 1973) and Israel (1978 and 1979). Along with Switzerland's win in the first contest, Serbia is the only other country to win with its debut entry (in 2007), though Serbia had competed prior as part of Yugoslavia and Serbia and Montenegro. Under the voting system used between 1975 and 2015, the winner of the contest was decided by the final voting nation on eleven occasions.
question: has a country won eurovision twice in a row?

SOLUTION:
Yes
