Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: FOR people who are interested in space, nothing is more exciting than the idea of living on other planets. That might be why the movie The Martian (<<>> ) is so popular. It shows an astronaut struggling to live on Mars. But would it actually be possible to live on the Red Planet? While the idea of living on Mars is great, the reality does not look as good. Mars does not have a friendly atmosphere for humans. There is very little oxygen there. And because of its distance from the sun, it is also very cold. The temperature on Mars can be -62 degrees on average. This is much too cold for humans. However, scientists say it might be possible to live there even without a good atmosphere. Daytime on Mars is almost the same as Earth's. It means there's enough sunlight to grow plants inside safe buildings. However, they would have to grow in soil from Earth. Mars does not have a strong enough atmosphere to stop the radiation coming from space, which makes it dangerous to grow things in the soil. The radiation is also bad for our health. If we want to live there healthily, we need to build our homes under the ground or within the rocks on the planet. This would protect humans from the radiation and also some heat. When could we actually live on Mars? NASA is hoping to make some progress within the next 20 years. Options: A there is enough sunlight B the soil is good on Mars C it has a good underground atmosphere D its temperature changes very little Answer: A there is enough sunlight Question:

A: It's possible to grow plants on Mars because _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they create a food chain . Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears. All life needs sunlight to live on. But only plants can use sunlight directly. Plants are 'factories'. They make food from sunlight, water and things in the soil and air. Plants feed all other living things. Animals can only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly. What about humans? We are members of many food chains. We eat rice, vegetables, and fruits and so on. We also eat meat and drink milk. But we often break up the food chains. We kill wild animals and also make rivers, lakes and seas polluted. When these rivers, lakes and seas are polluted, the fish in them can not be eaten. If we eat the fish, we will get strange illnesses. Each form of life is linked to all others. Breaking the links puts all life in danger. Options: A Animals. B Plants. C Animals and plants. D All living things. Answer: B Plants. Question:

A: Which living things can use the sun's energy directly?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone. And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it. We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun just as the sun and the moon raised its tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets. Options: A the large tidal wave B the powerful tidal pull C the star coming near the sun D one of sun's planets Answer: C the star coming near the sun Question:

A:
The expression "the cause of the disturbance" refers to _ .
