Passage 1

Even the newest gardener realizes that plants die without water; what is not so well known is that plants die equally decisively, though not so quickly, if they are over watered. Beginners usually decide to play it safe and keep their potted plants thoroughly wet. In consequence, death by drowning is one of the commonest disasters to befall the plants of a new horticulturist. Plants wither away if they don't get enough water, and this draws attention to their problem.

A plant that has been slightly under watered so that it droops strikes terror into the heart of its new owner. But it will, in fact, recover completely as long as rescue comes in time and the process is not repeated too often. Over watered plants, unfortunately, do not give any such obvious signal; slowly they cease to thrive and the first visible indication of serious trouble is a yellowing of the lower leaves. Unless the over watered pot soil is given a considerable period without water, during which time the plant will continue to look wretched, it will suddenly collapse in exactly the same way as the under watered plant --- but with no chance of being revived because the roots have rotted away. √1. Judging from the text, a horticulturist is one who ____.

[A] raises animals

[B] grows plants

[C] gives advice to new gardeners

Passage 2

Every human being, no matter what he is doing, gives off body heat. The usual problem is how to dispose of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the opposite problem -- how to collect body heat. They have designed a collection system which utilizes not only body heat, but the heat given off by such objects as light bulbs and refrigerators as well. The system works so well that no conventional fuel is needed to make the campus's six buildings comfortable.

Some parts of most modern buildings--theaters and offices as well as classrooms -- are more than amply heated by people and lights and sometimes must be airconditioned even in winter. The technique of saving heat and redistributing it is called "heat recovery". A few modern buildings recover heat, but the University's system is the first to recover heat from some buildings and reuse it in others.

Along the way, Pitt has learned a great deal about some of its heat producers. The harder a student studies the more heat his body gives off. Male students emit more heat than female students, and the larger a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hard-working, overweight male genius. √5. Which of the following is true of the heating system of the Johnstown campus?____

[A] The heat is supplied by human bodies.

[B] The heat is supplied by both human bodies and other heat-emitting objects.

[C] The heat is supplied by both human bodies and conventional fuel.

[D] The heat is supplied by human bodies, other heatemitting objects, and conventional fuel.
