Q: 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?

A: Yes

Q: passage: During the 19th century many of the smaller German and Italian states were ruled by Dukes or Grand Dukes. But at present, with the exception of the Grand Duchy of Luxembourg, there are no dukes ruling as monarchs. Duke remains the highest hereditary title (aside from titles borne by the reigning or formerly reigning dynasty) in Portugal (though now a republic), Spain, and the United Kingdom. In Sweden, members of the Royal Family are given a personal dukedom at birth. The Pope, as a temporal sovereign, has also, though rarely, granted the title of Duke or Duchess to persons for ``services'' to the Holy See. In some realms the relative status of ``duke'' and ``prince'', as titles borne by the nobility rather than by members of reigning dynasties, varied--e.g., in Italy and the Netherlands.
 question: do you have to be married to be a duke?

A:
No
