(Question)
Read the following article and select the best answer. Article: Our world is a noisy place, but quiet places remain. Eight years ago, audio engineer Gordon Hempton identified the quietest place in the continental United States. He calls the place "One Square Inch of Silence." He has used his symbolic spot in a northwestern rain forest to campaign against noise pollution. But the self-described "Sound Tracker" is now going deaf. For Gordon Hempton, it started with an experience known to many people. "I was lying in the bed in the springtime about a year ago. The sun was shining. The birds could be singing. They should be singing. But I was hearing none. I knew my life was going to be different." Hempton's eyes get watery as he describes his cruel situation. More than 20 years ago he trademarked his nickname as "The Sound Tracker." Sharp hearing defined his career as an Emmy award winning sound recordist. It also led to his activism against noise pollution. He has circled the globe three times in search of the perfect sounds of nature. Hempton says his hearing loss is quickly getting worse but he has to finish his project. "I am running a race to finish the Quiet Planet collection." That's the title of a planned 19-volume set of nature recordings. The sound tracks could be licensed for use in movies, video games, exhibits, plays and the like. Volunteer assistants now help Hempton review and edit sound files and identify imperfections. The exact cause of his hearing loss is not clear. Doctors say it may be the result of an infection, or a tumor or a combination of things. Hempton is self-employed. His health care plan does not pay for hearing loss treatment. So, for now, he's directing his attention to completing his "greatest hits" album. "After I get it finished, I have an economic cash flow to get my hearing back. That's the first thing on my to-do list." He's hopeful his hearing loss can be recovered. Question: What may be the best title of the text? - Searching for the sound of nature. - Hoping to get the hearing back. - Deaf fighter against noise pollution. - Successful Sound-Tracker going deaf.
(Answer)
Successful Sound-Tracker going deaf.

Question: Read the following article and select the best answer. Article: Treat with Respect The speed with which Man is changing the face of Earth has outstripped all the mighty processes of nature put together. In his haste to supply himself with increasing quantities of Earth's treasures he risks destroying one he greatly needs, his natural surroundings. Some countries set aside unspoiled areas of natural beauty. prefix = st1 /Canadahas the largest system of national parks in the world, 29 in all covering about 13 million hectares, preserving the different landscapes and the plant and animal life. Other countries are restoring areas which have been reduced to waste land by mining. At Broken Hill in Australiadrifting sand from rock crushing turned the area into a desert swept by sand storms. This is now being irrigated, fertilized and planted with grass and trees. In Great Britain quarries and gravel pits are being filled in or made into lakes, industrial wasteland is being turned into playing fields and waste tips into sloping green hills. However Man tries to look after Earth, the fact is that he is using up at a great rate resources, especially fuel resources, which have taken millions of years to accumulate and which he cannot renew. Yet every day the Earth receives a huge supply of energy from the Sun. Man has made several experiments in using solar energy to heat furnaces , cookers, and water-distillers. In space technology, e.g. on satellites, solar cells convert sunlight into electricity. Houses and offices have been designed which are centrally heated by water or air heated by the sunlight. When Man can trap and store this energy, so that he can use it exactly as he needs it, he will have not only an endless supply, but a clean and safe one. Question: Which of the following statements do you think is true after reading the passage? - Man is destroying the natural surroundings on purpose because the surroundings cannot make them satisfied to get enough treasures. - All the wasteland throughout the world is now being irrigated, fertilized and planted with grass and trees. - Where there is a desert, there can be sand storms. - Energy from waters, forests, fuel resources and the sun takes millions of years to accumulate.
Answer:
Where there is a desert, there can be sand storms.
