It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators. From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury. The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room. On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing. Question: The writer suggests that   _ - breathing in smoke might be harmful - smoke will enter the room through an open window - fresh air can't reach the second floor window - to keep you head low will help you to escape a fire
Answer: smoke will enter the room through an open window

Question: Read the following article and select the best answer. Article: The summer has seen a series of marine disputes involving China, Japan, South Korea, Vietnam, Taiwan and the Philippines. This week there were more anti-Japanese riots in cities across China because of a dispute over a group of uninhabited islands known to the Japanese as the Senkakus and to the Chinese as the Diaoyu Islands. One Chinese newspaper has helpfully suggested skipping the pointless diplomacy and moving straight to the main course by serving up Japan with an atom bomb.  The government in Beijing is trying to play down the dispute, aware of the economic interests in keeping the peace. China is re-emerging after what it sees as 150 years of humiliation, surrounded by anxious neighbours, many of them allied to America. In that context, disputes about _ could become very significant. Whatever the legality of Japan's claim to the islands, its roots lie in empire-building. China's leaders now face sharp criticism if they do not fight their country's corner. A recent poll suggested that over half of China's citizens thought the next few years would see a "military dispute" with Japan.  The islands matter, therefore, less because of fishing, oil or gas than as counters in the high-stakes game for Asia's future. Japan, Vietnam and the Philippines fear that if they give in, China will sense weakness and prepare the next demand. China fears that if it fails to press its case, America and others will conclude that they are free to scheme against it.  Asia's inability to deal with the islands raises doubts about how it would cope with a genuine crisis, on the Korean peninsula, say, or across the Strait of Taiwan. And the tendency for the slightest quarrel to turn into a full-blown conflict presents problems for America, which both aims to reassure China that it welcomes its rise, and also uses the threat of military force to guarantee that the Pacific is worthy of the name. Question: The most important reason for the dispute about the Diaoyu Islands is that  _  . - the scenery there is so beautiful - the natural resources are so rich - fish are abundant in the waters - they greatly affect Asia's future
Answer: they greatly affect Asia's future
