[Q]: Article: A study of a million UK women, published today in The Lancet, has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect. Life-threatening poor health can cause unhappiness, and for this reason unhappiness is associated with increased mortality. In addition, smokers tend to be unhappier than non-smokers. However, after taking account of previous ill health, smoking, and other lifestyle and socio-economic factors, the investigators found that unhappiness itself was no longer associated with increased mortality. The lead author, Dr Bette Liu, now at the University of New South Wales, Australia said: "Illness makes you unhappy, but unhappiness itself doesn't make you ill. We found no direct effect of unhappiness or stress on mortality, even in a ten-year study of a million women." As in other studies, unhappiness was associated with deprivation, smoking, lack of exercise, and not living with a partner. The strongest associations, however, were that the women who were already in poor health tended to say that they were unhappy, stressed, not in control, and not relaxed. The main analyses included 700 000 women, average age 59 years, and over the next 10 years these women were followed by electronic record linkage for mortality, during which time 30 000 of the women died. After allowing for any differences already present in health and lifestyle, the overall death rate among those who were unhappy was the same as the death rate among those who were generally happy. The study is so large that it rules out unhappiness being a direct cause of any material increase in overall mortality in women. This was true for overall mortality, for cancer mortality, and for heart disease mortality, and it was true for stress as well as for unhappiness.
Question: The word "mortality" in the passage means .
Options: (A) richness (B) relaxation (C) death (D) morality
[A]: B

[Q]: Article: There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since. The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20 000 light years ago).Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility of a manned flying saucer landing on Earth.A press conference was held at the Venus Institute of Technology. "We have come to the conclusion,based on last week's satellite landing," Pro. Zog said,"that there is no life on the Earth." "How do you know this?" the science reporter of the Venus Evening Star asked. "For one thing, Earth's surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive." "What does this mean as far as our flying saucer program is concerned?" "We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. " "Are there any other hazards that you discovered in your studies?" "Take a look at this photo. You see this dark cloud floating over the surface of Earth? We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there." "If what you say is true, won't this set back the flying saucer program several years?" "Yes, but we shall proceed as soon as the Grubstart gives us the added funds." "Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?" "Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere."
Question: During the week of great excitement the Venusian scientists succeeded in getting important information on whether they can _ .
Options: (A) land a satellite with Venus astronauts on Earth (B) make a firstrate flying saucer (C) get a Earth Being to Venus (D) direct a flying saucer into Manhattan
[A]: A

[Q]: Article: Tokyo, the capital of Japan, is one of the largest cities in the world. It is also one of the world's most modern cities. Twice last century, the city was destroyed and rebuilt. In 1923 a major earthquake struck the city. Thousands of people were killed and millions were left homeless as buildings collapsed and fires broke out throughout Tokyo. It took seven years to rebuild the city. During World War II, Tokyo was destroyed once again. As a result of these disasters, there is nothing of old Tokyo remaining in the downtown area. After the war, the people of Tokyo began to rebuild their city. Buildings went up at a fantastic rate, and between1945 and 1960, the city's population more than doubled. Because of the Olympic Games held in Tokyo in 1964, many new stadiums, parks and hotels were built to treat visitors from all over the world. As a result of this rapid development, however, many problems have risen. Housing shortage, pollution, and waste disposal have presented serious challenges to the city, but the government has begun several programs to answer them.
Question: What major event(s) happened in Tokyo last century?
Options: (A) Its population was doubled. (B) It was twice destroyed by natural disasters and was twice rebuilt. (C) Serious social problems emerged. (D) It was ruined by an earthquake and a war, but was twice rebuilt.
