Though he gained fame as a magician and escape artist, Harry Houdini, born Erik Weisz, was also a well-known skeptic of spiritual practices. After his mother died in 1913, he tried to contact her through a medium at a séance and saw through the medium's sleight-of-hand tricks. He launched a public campaign against so-called mystics. His 1923 book, A Magician Among the Spirits, accused mediums of defrauding grieving people and explained how common séance illusions were performed. He put his stage show on hold that year to go on a lecture tour supporting the book. By 1925, he was offering $10,000 to any medium whose tricks he couldn't figure out. He never had to pay up.

Read the passage about hummingbirds and answer the question below. When you think of a hummingbird, you most likely think of a very small creature with rapidly beating wings. No surprise that the hummingbird family contains the smallest bird in the world. Somewhat more surprising is the fact that there are more than 400 kinds of hummingbirds, 19 of which are found in the United States. It turns out that plenty of diversity can be packed into small packages; one thing all hummingbirds have in common is their ability to amaze. The smallest hummingbird is no longer than an adult bumblebee; the largest, the giant hummingbird, grows from 2 to 4 inches in length. Despite their diminutive stature, these birds can do many incredible things. They are the only birds that can fly backward, and their wings beat faster than those of any other bird 60 to 70 times per second. In the eastern United States, the ruby-throated hummingbird is the only kind commonly found north of Florida. While both males and females have a coat of brilliant metallic green, only the male has a bright red throat. The male is very aggressive in defending food sources, often taking on enemies much larger than himself. A mature ruby-throated hummingbird is only about 3 to 4 inches long; when newly hatched, three of the birds can fit inside a nest the size of a large thimble. The birds eat insects and extract nectar from flowers for their diet. Many people hang hummingbird feeders containing sugar water, and hummingbirds flock to them. Feeders are an important supplement to their natural diet. Although they weigh as little as a penny, hummingbirds have long migration routes to follow in spring and fall. They are marvels of speed, agility, and beauty. Which of the following is a logical conclusion based on the passage?
A doctor recommends that her patients eat a diet that is high in protein but moderate in sodium. Which of the following meats would be the best choice for this diet?

Sleepwalking is a common phenomenon; in fact, estimates for the number of sleepwalkers in the United States range into the millions. However, for many, this odd ailment still remains a baffling and potentially dangerous problem. For instance, a woman from the Midwest went sleepwalking one June night and made national headlines. Dressed in her pajamas, the woman wandered from her home and climbed a nearby tree to pick leaves some 20 feet above the ground. Soon a crowd of fascinated neighbors gathered to watch her sleepwalking acrobatics. While they watched, her husband climbed up the tree, wrapped a jacket around her, tapped her gently on the shoulder to awaken her, and then lowered her, somewhat shaken by her nighttime roving, into the net the firemen had spread below. This woman's feat may have been the most spectacular sleepwalking performance that June night, but it was far from the only one. That same night, in homes across America, thousands of others were sleepwalking. Authorities have estimated that there are some 4 million sleepwalkers in this country. It is far from surprising, then, that we all know of cases of it, even in our own families. Despite the fact that sleepwalking, or noctambulation, occurs frequently, this odd ailment remains a baffling, uncanny, if not frightening, phenomenon. One of the chief reasons for this has been the marked tendency of newspapers and other media to play up, as they did in this woman's case, only the most bizarre sleepwalking antics. Reports have shown that sleepwalkers perform remarkable feats of memory; climb up on steep roofs; write letters; solve intricate mathematical problems; play the piano or some other musical instrument; compose music; and commit robbery, suicide, or murder. There is simply no end to the stories of the weird feats that sleepwalkers are allegedly capable of performing. What is the meaning of "uncanny," as used in the 4th paragraph of the passage?
