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.

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?
Yes

passage: When a traffic stop is made, a warning issued by the officer is a statement that the motorist has committed some offense, but is being spared the actual citation. Officers use their own discretion whether to issue a citation or warning. The motorist may receive the warning either verbally or written, but will not be charged with the offense, will not have to pay a fine, and will not receive any points. Depending on the laws of the jurisdiction, the warning may or may not appear on records visible to officers, which, if it does, could result in another stop within a fixed period of time leading to an actual citation, or in some cases, the motorist may be charged with both offenses.
 question: do you have to pay for a warning ticket?
No

passage: However, these changes were soon followed by studies showing an increase in motor vehicle fatalities attributable to the decreased MLDA. In response to these findings, many states raised the minimum legal drinking age to 19 (and sometimes to 20 or 21). In 1984, the National Minimum Legal Drinking Act, written by Senator Frank Lautenberg (D-NJ) and influenced by Mothers Against Drunk Driving (MADD), required all states to enforce a minimum legal drinking age of 21 or else risk losing 10% of all federal highway construction funds.
 question: is the drinking age 21 everywhere in the us?

Yes
