问题     Mass travel is just that -- travel for the masses. Over 600 hundred million people will fly, drive, sail or go by train to a foreign destination this year.
    Global earnings from tourism this year will exceed $ 450 billion. Within the next fifteen years, the tourism business is expected to expand fourfold and to generate receipts in excess of $ 1.5 trillion, according to the World Travel Organization. Add in other types of travel, such as business, to recreational travel and you have an industry that is worth perhaps double that amount -- and employs more than 200 million people worldwide.
    Nowhere is exempt from this explosion of movement. From the most remote island in the Pacific to the deepest valley in the Himalayas and the driest areas of Sahara, tourism is leaving its mark. Toilets for tourists are now provided at base camps on the slopes of Mount Qomolangma. Special landing craft fan out from luxury ships to explore the most remote beaches in the Galapagos Island.
    Europe remains the motor of this industry, although its old dominance is slipping in the face of Asian competition. Today, 60% of all tourist arrivals are in Europe,(down from 69% in 1975), and receipts for tourism at $ 214 billion are more than three times higher than those in the US( $ 64 billion). No fewer than one in five tourists(120 million 1997)go to the Mediterranean alone.
    Tourism is a mixed blessing. Tourism generates wealth, employment -- and enjoyment, at least, for the tourists. However, it has its downside, too.  Environmentalists who wish to protect the world’s beauty spots, peasants in developing countries forced off their land to make room for tourists’ golf courses, governments worried about "moral pollution" are just a few of those uneasy at the sudden and startling democratization of travel. Nor should we forget exhausted air traffic controllers, coping with greatly increased numbers of aircraft queuing to take off and land.
The explosion of movement refers to __________.
选项
答案the rapid development of tourism
解析 第三段中第一句就提到了this explosion of movement，并在随后的句子中举例加以说明。由this一词可推知应该到第二段中去理解这种说法的含义。第二段中先后提到了earnings、expand、add、employ等词，归纳起来，explosion of movement 就是指the rapid development of tourism。
