TEXT B Why do you teach My friend asked the question when I told him that I didn’t want to be considered for an administrative position. He was puzzled that I did not want what was an obvious "step-up" towards what all Americans are taught to want when they grow up: money and power. Certainly I don’t teach because teaching is easy for me. Teaching is the most difficult of the various ways I have attempted to earn my living: mechanic, writer, carpenter. For me teaching is a red-eye, sweaty-palm, sinking-stomach profession. Red-eye, because I never feel ready to teach no matter how late I stay up preparing. Sweaty-palm, because run always nervous before I enter the classroom, sure that I will be found out for the fool I am. Sinking-stomach, because I leave the classroom an hour later convinced that I was even more boring than usual. Nor do I teach because I think I know answers, or because I have knowledge I fell compelled to share. Sometimes I am amazed that my students actually take notes on what I say in class! Why then do I teach I teach because I like the pace of the academic calendar. June, July and August offer an opportunity for reflection, research, writing. I teach because teaching is a profession built on change. When the material is the same, I change--and, more importantly, my students change. I teach because I like the freedom to make my own mistakes, to learn my own lessons, to stimulate myself and my students. As a teacher, I’m my own boss. If I want my freshmen to learn to write by creating their own textbook, who is to say I can’t such course may be huge failures, but we can learn from failures. I teach because I like to ask questions that students must struggle to answer. The world is full of right answers to bad questions. While teaching, I sometimes find good questions. I teach because I enjoy finding ways of getting myself and my students out of the ivory tower and into the real world. I once taught a course called "Self-Reliance in a Technological Society". My 15 students read Emerson, Thoreau and Huxley. They kept diaries. They wrote term papers. But we also set up a corporation, borrowed money, purchased a run-down house and practiced self-reliance by renovating it. At the end of the semester, we sold the house, repaid the loan, paid our taxes and distributed the profits among the group. So, teaching gives me pace and variety, and challenge, and the opportunity to keep on learning. Which of the following is a fact rather than an opinion

TEXT E At dusk, a sparrow flies through the dark woods in search of a meal. Spotting a plump hawkmoth clinging to a large tree trunk, the bird lands on a nearby branch. Moving in for the attack, the sparrow suddenly spies a pair of round, menacing eyes. The eyes seem to move up and down like those of an owl. Within a second, the sparrow is all tail feathers as it makes its retreat. But what about the moth In order to avoid being eaten, the moth practised a bit of natural "tom foolery" by exposing its secret weapon--eyespots on its wings. Eyespots are round markings or colorations on animals which look like real eyes. Many in- sects, as well as fish and frogs, use them--in a variety of ways--as a defense against predators. Eyespots can scare an attacker away--as in the case of the moth above--by making the attacker think it is facing one of its predators. Or they can simply fool predators into thinking they are being watched. Even when the false eyes don’t stop an attack, they may enable the one who wears them to survive. You see, eyespots are often located "far" from vital organs, on wings, for instance. They lure predators into attacking the "wrong end" of their prey. The tropical butterfly fish, for example, has an eyespot at the base of its tail. Predatory fish will often try to attack this spot, confusing the dark circle for a real eye--only to find the fish escaping in a completely unexpected direction. The eyespots on a peacock butterfly’s wings work in a similar way. By luring the predator to the wings instead of the body, the eyespots protect the peacock butterfly’s head from attack. Although the insect may lose a claw or suffer a clipped wing, at least it hasn’t lost its head! Eyespots work because they take advantage of a weakness in predators, known as "innocence of the eye." Basically, this means that animals believe what they see. Unlike humans, some animals cannot reason beyond what their instincts and past experiences tell them. So, if something looks like an eye to a predator, then it must be an eye--even if it graces the delicate wing of a butterfly. The hawkmoth escaped the attack from the sparrow because ______.
