Read the following article and select the best answer. Article: Our first winter in Canada was the happiest we have experienced. We were living in the countryside then and had just arrived from Hong Kong that autumn. One evening in mid December snow began to fall. When we looked out of the window and saw that it was snowing, we all cheered. It was the first snow we had ever seen and we were excited. We could hardly wait for the snow to stop so that we could go out to play. Next morning when we woke up, it was still snowing. We switched on the radio and learned that more than ten inches of snow had falled during the night and that since the roads were blocked there would be no school that day. We jumped up and down for joy and begged mother to let us go outside to play in the snow. She said we could go out after breakfast if we dressed ourselves warmly and promised to come back as soon as we felt cold. When we went out, the snow had almost stopped. The roads , paths, gardens, and playing grounds were all hidden under a white blanket of soft snow. It was the most beautiful sight we had ever seen. Just then, we saw some neighbour's children coming out to play. We ran over to join them. Together we built a snowman and a snow house. After that, we took turns sliding down a hill on a large piece of cardboard. We were having so much fun when supper time came. Mother almost had to force us to go in and eat. Question: The writer and his brothers and sisters built _ . - a snowman and a cardboard house of their own - a snowman and a snow house for themselves to live in - a snowman and a snow house with their neighbors' children - a white blanket on the roads
(Answer)
a snowman and a snow house with their neighbors' children

Read the following article and select the best answer. Article: As in the field of space travel, new technologies continue to appear in undersea exploration. They share a number of similarities with each other -- as well as some important differences. Manned submersibles , like spaceships, must maintain living conditions in an unnatural environment. While a spaceship must simply be sealed against the vacuum space, a submersible must be able to bear extreme pressure if it is not to break up in deep water. In exploring space, unmanned vehicles were employed before astronauts. In undersea exploration, on the other hand, men paved the way, and only recently have unmanned remote-operated vehicles (ROVs) been put to use. One reason for this is that communicating with vehicles in orbit is much easier than talking to those underwater. A vacuum is an ideal medium for radio communications, but underwater communications are limited to much slower sound waves. Thus, most undersea vehicles -- particularly ROVs -- operate at the end of long ropes. For a similar reason, knowing where you are undersea is much more difficult than in space. A spaceship's position can be located by following its radio signal, or by using telescopes and radar. For an undersea vehicle, however, a special network of sonar devices must be laid out in advance on the ocean floor in the area of a dive to locate the vehicle's position. Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: going to the ocean depths doesn't require the power necessary to escape Earth's gravity. Thus, it remains far less expensive. Question: The purpose of the passage is _ . - to persuade you to explore the depths of the ocean - to stress the importance of the undersea exploration - to make you believe that the undersea exploration is better - to tell some differences between two kinds of explorations
(Answer)
to tell some differences between two kinds of explorations

Read the following article and select the best answer. Article: American doctors have been trying to figure out the secrets behind Asians being healthier than Americans since the early 90s - The Japan has the lowest mortality rates in the world and Chinese medicine has been around for thousands of years, since around 2000 B.C. only meant that there's more to Asian health philosophy. In Asian medicine, there's an acknowledgment of the whole-body theory of medicine, instead of isolationism that's prevalent in many American doctor's offices. The main reason behind a better health lies in the difference between Asian and American culture. Diet, exercise, and a holistic approach to medicine all contribute to Asians living longer and healthier than their American counterparts. In addition, the result of the Asian lifestyle has led to a stronger overall immune system and better detoxification efficiency. The more preferred drink in the American lifestyle is soda, beer or coffee. However, in Asian culture, the preferred drink is water or herbal tea. Consumption of water serves to immediately strengthen one's body detoxification program, since water dilutes toxins and helps flush the body. Americans savor red meat and pork, while most Asians prefer chicken, rice and fish. Also, the foods in Asia are mostly organic and lack the hormonal toxins that American food carries. Overall the Asian diet leads to less food-introduced toxins into the body, and allows the body to spend its energy on its immune system rather than toxin control. Also, the fish that Asians consume have very strong immunological effects, providing more antioxidants than the red meat preferred in America. The average American family has more than one car. In Asia, on average there's 1 car per 4 families. In Asian cultures, people use bicycles more than four-wheeled transportation. The Asian lifestyle also involves more labor and physical work, such as agricultural labor and gardening. The American lifestyle praises white-collar jobs which lead to Americans sitting in front of computer screens for hours on end.... Question: The differences between Asian and American culture are not discussed in _ - Diet - Exercise - Medicine - Accidents
(Answer)
Accidents
