阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。A In what now seems like the prehistoric times of computer history, the earth’s postwar era, there was quite a wide-spread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction. Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong. Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer may provide; it should not be seen as a substitute for fundamental thinking and reasoning skills. According to the passage, the initial concern about computer was that they might ______.

B Life on land probably began about 430 million years ago, though it has existed in the water for perhaps much as 3 000 million years. When we think of the first life on land, we probably think of strange animals coming out of the oceans, but, in fact, no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessary, since the plants are the only form of life that is able to get and store energy. The first plants to exist out of the water were probably certain kinds of algae (海藻) which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once their move to land had been made, however, evolution (进化) took place quickly. By the end of 100 million years, plants had developed their roots (根), and some had got tree-like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modem trees. They had roots, leaves, wood, but mostly they had not developed seeds. Which of the following is true
