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: Walt Disney's Carousel of Progress is a rotating theater stage show attraction that is located in Tomorrowland at the Magic Kingdom theme park at the Walt Disney World Resort in Bay Lake, Florida just outside of Orlando, Florida. Created by both Walt Disney and WED Enterprises as the prime feature of the General Electric (GE) Pavilion for the 1964 New York World's Fair, the attraction was moved to Tomorrowland at Disneyland in Anaheim, California as Carousel of Progress, remaining there from 1967 until 1973. It was replaced in Disneyland by America Sings in 1974, and reopened in its present home in the Walt Disney World Resort's Magic Kingdom in 1975.
question: does disney world still have the carousel of progress?
Yes

passage: The peace treaty left the United States independent and at peace but with an unsettled governmental structure. The Articles envisioned a permanent confederation, but granted to the Congress--the only federal institution--little power to finance itself or to ensure that its resolutions were enforced. There was no president, no executive agencies, no judiciary and no tax base. The absence of a tax base meant that there was no way to pay off state and national debts from the war years except by requesting money from the states, which seldom arrived. Although historians generally agree that the Articles were too weak to hold the fast-growing nation together, they do give credit to the settlement of the western issue, as the states voluntarily turned over their lands to national control.
question: were the articles of confederation effective in binding the states together?
No
