The roadrunner is a familiar desert bird. It is famous for being able to run very fast—at speeds greater than 15 miles per hour. This bird is so quick that it can catch a rattlesnake. It can even capture a dragonfly or a hummingbird in the air. There is not much a roadrunner won’t try to catch and eat. Rodents, lizards, and spiders are all favorite foods. The roadrunner clearly uses its speed to catch prey, but it also uses its speed to escape from enemies. It can fly, but it rarely does, so being able to run fast on strong legs is important.
Which two statements support the central idea in paragraph 3 that roadrunners are fast?
a. They like to eat spiders.
b. They catch dragonflies in the air.
c. They are well known to most readers.
d. They run more than 15 miles per hour.

The roadrunner gets most of its water from eating other animals, but it also has ways to make the most of its water supply. Water sources in the desert can be salty, and too much salt can be harmful.

During this time, it needs less water.

a. It leads the roadrunner to search for salt.
b. It leads the roadrunner to fly sometimes.
c. It leads the roadrunner to hunt in the evening.
