Read the following article and select the best answer. Article: Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means. Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach. Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth. Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar. Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly leaves, and each prickle contains poisonous venom A single experience with this kind of plant will teach an animal to stay away from it in the future. Question: To defend themselves, oak trees use _ . - chemical means - physical means - bitter chemicals - sandy materials

Read the following article and select the best answer. Article: You are busy filling out the application form for a position you really need; let's assume you once actually completed a couple of years of college work or even that you completed your degree. Isn't it tempting to lie just a little, to claim on the form that your diploma represents a Harvard degree? Or that you finished an extra couple of years back at State University? More and more people are turning to an utter deception like this to land their first job or to move head in their careers. For personnel officers, like most Americans, value degrees from famous schools. A job applicant may have a good education anyway, but he or she assumes that chances of being hired are better with a diploma from a well-known university. Registrars at most well-known colleges say that they deal with dishonest claims like these at the rate of about one per week. Personnel officers do check up on degrees listed on application forms. If it turns out that an applicant is lying, most colleges are unwilling to accuse the applicant directly. One lvy League school refers to them as "special cases", One well-known West Coast school, in perhaps the most delicate phrase of all, says these claims are made by "no such people". To avoid complete lies, some job seekers claim that they "attended" or "were associated with" a college or university. After careful checking, a personnel officer may discover that "attending" means being dismissed after one semester. It may be that "being as sociated with" a college means that the job-seeker visited his younger brother for a football weekend. One school that keeps records of false claims says that the practice dates back at least to the turn of the century--that's when they began keeping records, anyhow. If you don't want to lie or even stretch the truth, there are companies that will sell you a fake diploma. One company, with offices in New York and on the West Coast, will put your name on a diploma from any number of non-existent colleges. The price begins at around twenty dollars for a...
