Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)
Back in July 1965, the Mariner Four Space Probe transmitted the first close-up pictures of Mars and convinced many people that Mars was as dead as our own moon. Two later space probes seemed to confirm this.
But then, in 1971, Mariner Nine raise hopes once again that there could be life on the planet—or at least that life might once have existed there. The range of experiments to be conducted were designed by mission scientists such as Chuck Klein:
"It was like shooting blind, so to speak, to be trying to devise experiments to look for evidence of life. And we decide to try to use an instrument which could incorporate many different assumptions about what Martian biology might be like—what the bugs might be like or not like. But the fundamental proposition in each portion of our experiment was to look, over a period of time, for evidence of some process going on which we could attribute to biology."
The scientists controlled the Viking experiments from a distance of almost 100 million kilometers. Cameras took pictures of the area a round the robot landers—in case anything moved into view. No aliens were spotted by the cameras, but other experiments seems to show signs of life.
"Almost everything that we planned began to give us data of some kind—that is to say, it wasn't like everything was dead. For many weeks, we were goaded by the media, who were terribly excited—they were constantly looking for a headline, you know. They Found Life! They Found Life! Every bit of information that we came up with was squeezed by them to try to put a positive twist on it. We really had to work very hard to maintain our cool and present the data just the way we saw it."
But these apparent signs of life were deceptive. By repeating the experiments and double checking the results, the scientists eventually came to the conclusion that the whole planet was dead and would, in fact, be deadly to living organisms.
Since 1976, there have been no further visits. A probe sent by NASA exploded before reaching the planet last year and it now doesn't look as if there'll be another Mars visit until the end of the decade.
When we do get back there, will we find something new？ And what about us？ Could we ever live on Mars？ This isn't as strange an idea as it sounds according to astronomer Patrick Moorer.
"It's fair to say that, from a technical point of view, we could put men on Mars within the next few decades. Whether we actually do so or not depends very much more upon politics and finance than upon sheer science, but I think it could be done. And I'm quite prepared to believe that by this time in the next century, there will be flourishing colonies upon Mars."
Which of the following is closest in meaning to the sentence "It was shooting blind.., to look for evidence of life..."

Using sophisticated measuring devices, science is learning more and more about the far-reaching and often surprising impact humidity has on all of us.
Two summers ago angry callers phoned American Television and Communications Corp.'s cable-TV operation in northeastern Wisconsin, complaining about fuzzy pictures and poor reception. "What happened," said the chief engineer, "was that the humidity was interfering with our signals." When a blast of dry air invaded the state, the number of complaints dropped sharply.
Humidity plays hob with our mechanical world as well. Water condensation on the playing beads and tapes of videocassette recorders produces a streaky picture. Humidity shortens the life of flashlight and smoke-detector batteries. When the weather gets sticky, the rubber belts that power the fan, air conditioner and alternator under the hood of our cars can get wet and squeak.
Moisture also causes pianos to go out of tune, often in no time flat. At the Wolf Trap Farm Park for the Performing Arts in Vienna, where pianos are tuned twice a day during the summer concert season. Often a tuner stands in the wings, ready to make emergency adjustments during performances.
Humidity speeds the deterioration of treasured family photos and warps priceless antiques. Your home's wooden support beams, doors and window framers absorb extra moisture and expand-swelling up to three percent depending on the wood, its grain and the setting.
Too much moisture promotes blight that attacks potato and green-bean crops—adding to food costs. It also causes rust in wheat, which can affect grain-product prices.
Humidity affects our health, as well. We get more migraine headaches, ulcer attacks, blood clots and skin rashes in hot, humid weather. Since 1987, the Health, Weight and Stress Clinic at Johns Hopkins Hospital in Baltimore has tested over 1700 patients for responses to high humidity. They have reported increased dizziness, stomachaches, chest pains, cramps, and visual disturbances such as double and blurred vision.
The main idea of the passage is about ______.
