Choose the sentence that best expresses the implied main idea of the paragraph below. Working at home is convenient and flexible and can be less stressful than daily commuting. It can benefit employers (who need less space), employees (who save on clothing and transportation), and entrepreneurs (who save on office expenses). However, it is not for everyone: it requires enough initiative, independence, and self-confidence to work without supervision. Some home workers feel isolated or have trouble concentrating in the presence of such distractions as television, the refrigerator, and young children. Also, employees who work at home may lose fringe benefits, such as health insurance, and the protection of laws guaranteeing fair labor standards and working conditions.

In species such as the red-back spider, the black widow spider, the praying mantis, and the scorpion, the female commonly eats the male after mating. Another widespread form of cannibalism is size-structured cannibalism, in which large individuals consume smaller ones. Octopus, bats, toads, fish, monitor lizards, salamanders, crocodiles, spiders, crustaceans, birds, mammals, and a vast number of insects have all been observed to engage in size-structured cannibalism. Yet another common form of cannibalism is infanticide. Classic examples include the chimpanzees, where groups of adult males have been observed to attack and consume their infants; and lions, where adult males commonly kill infants when they take over a new harem after replacing the previous dominant males. Also, gerbils and hamsters eat their young if they are stillborn, or if the mothers are especially stressed.

Far from being America’s favorite food, during the early 1900s, hamburgers were considered “food for the poor.” Restaurants generally didn’t sell them. Burgers were served at lunch carts parked near factories, at circuses, and at carnivals. It was widely believed that ground beef was made from rotten old meat full of chemical preservatives. In the mid- 1920s, however, a man named Walt Anderson set out to defend the hamburger from its many critics. Walt loved burgers and opened a small restaurant devoted to selling them—the first White Castle—in Wichita, Kansas. Walt grilled the burgers right in front of his customers, so they could see for themselves that the meat and the equipment were clean. He also supported an unusual experiment at the University of Minnesota. For thirteen weeks, a medical student there consumed nothing but White Castle hamburgers and water. When the student not only survived the experiment but also seemed pretty healthy, people started to view hamburgers in a new light—as wholesome, not deadly.

Approximately 12 percent of men reported that their wives had engaged in physically aggressive behavior against them in the past year—nearly the same percentage of claims reported by women. The difference between male and female batterers is twofold. First, although their frequency may be similar, their impact is drastically different: women are typically injured in domestic incidents two to three times more often than are men. These injuries tend to be more severe and result in significantly more deaths. Women do engage in moderate aggression, such as pushing and shoving, at rates almost equal to those of men. But severe aggression that is likely to land a victim in the hospital is almost always male against female. Second, a woman who is physically abused by a man is generally intimidated by him; she fears that he will use his power and control over her in some fashion. Men, however, generally report that they do not live in fear of their wives.

Almost two thousand years ago, when Julius Caesar landed on the island we now know as Britain, the English language did not exist. Five hundred years later, a form of English called Old English (which was so different from modern English that you and I couldn’t even understand it) had emerged, and was spoken by only a few thousand people. By the late sixteenth century, when William Shakespeare was writing his greatest plays, English was the native language of five to seven million British people, but was not yet used anywhere outside of Britain itself. In the four hundred years since then, English-speakers such as the Scottish, the Irish, the Americans, and many others have carried their language and culture to all parts of the globe, and English has become the most widely spoken, written, and far-reaching language in human history. Today English is used by roughly a billion people, more than half of whom have learned it as a second language. It has become a global language of business as well as technology, appearing in 75 percent of the world’s mail and 80 percent of the information stored in the world’s computers.
