Article: In the late 1970's,many people in North America turned their attention to environmental problems ,and new steel -- and -- glass skyscrapers were widely criticized. Some ecologists pointed out that a number of tall buildings in a city often overburden public transportation. Skyscrapers are also _ of electric power and water. In just one recent year, the addition of 17 million square feet of skyscraper office space in New York City itself has already raised the top daily demand for electricity by 120, 000 kw -- enough to supply the entire city of Albany in New York area for a single day. Glass--walled skyscrapers can also be especially wasteful. The heat loss ,or gain, through a wall of half inch plate glass is more than ten times that through a typical ordinary wall filled with bricks or board. In order to decrease the pressure on heating and air -- conditioning equipment, builders of skyscrapers have begun to use double--layered glass ,and reflective glasses coated with silver or gold mirror films that could reduce glare as well as heat gain. However, mirror -- walled skyscrapers may raise the temperature of the surrounding air and affect neighboring buildings as well. Skyscrapers put a severe pressure on a city's sanitation facilities, too. If fully occupied, the towers just within the central area of New York would alone produce 2. 25 million gallons of waste water each year^--as much as the city size of Stanford, Connecticut, which has a population of more than 109,000. Question: Glass walls of skyscrapers are specially mentioned in order to _ . Options: A: show how skyscrapers manage to lessen their pressure B: explain why skyscrapers can control its air conditions C: describe further how wasteful skyscrapers could be D: present the stability of skyscrapers in modern buildings

Question: Read the article and select the best answer. Article: It's about the size of a small slim upside down goat, if you can imagine such a thing.The sloth really is not only one of the laziest, but one of the strangest of the strangest of mammals.It spends most of its life asleep.But even when it's awake, it only moves very slowly. There are two main kinds defined by the number of toes that they have on their font legs.It's the three-toed which has really slothful habits, and the one that interests me most.You're not likely to have seen it in zoos, for unlike the two-toed which will rat all kinds of vegetables and fruits,, the three-toed is really picky and will only accept leaves and fruits of a few particular kinds, which few zoos can supply.And in any case, it doesn't make an exactly fascinating exhibit, since it spends most of its tile sleeping. When the skins and skeletons of this extraordinary beast reaches Europe, artists given the task of illustrating the species in natural history books, showed it standing upright on its four thin legs, even though thee hooks on its feet and the fur on its body all pointed very obviously in what you might call the wrong way.After all, the artists must have said to themselves, it would be too ridiculous to show it as animal that spent all its life upside down. Sloths are only capable of a faint wheeze and occasional whistle.These sounds are probably only made to deter a meat-eater like a lion, and certainly not to communicate with one another, for sloths are virtually stone deaf.It's said that an enthusiastic zoologist investigating the hearing ability of sloths fired his gun close to _ .It slowly raised its head, blinked at the scientist, and then went back to sleep again. Question: The underlines word"one"refers to _ . Options: A: one o'clock B: one gun shot C: A sloth D: one scientist
Answer:
C
