Questions from 36 to 40 are based on the following passage: In addition to visible trade, which involves the import and export of goods, there is also invisible trade, which involves the exchange of services between countries. Transportation service across national boundaries is an important kind of invisible trade. International transportation involves different means of transport such as ocean ships, planes, trains, trucks and inland water vessels. However, the most important of them is maritime ships. When an export arranges shipment, he generally books space in the cargo compartment of a ship or charters a whole vessel. Some countries such as Greece and Norway have large maritime fleets and earn a lot by way of this invisible trade. Insurance is another important kind of invisible trade. In the course of transportation, a cargo is vulnerable to many risks such as collision, pilferage, fire, storm, exploration, and even war. Goods being transported in international trade must be insured against loss or damage. Large insurance companies provide service for international trade and earn fees for other nations’ foreign trade. Lloyd’s of London is a leading exporter of this service. Tourism is yet another important form of invisible trade. Many countries may have beautiful scenery, wonderful attractions, places of historical interest, or merely a mild and sunny climate. These countries attract large numbers of tourists, who spend money for traveling, hotel accommodations, meals, taxis, and so on. Some countries depend heavily on tourism for their foreign exchange earnings, and many countries are making great efforts to develop their tourism. The fourth type of invisible trade meriting attention is called immigrant remittance. This refers to the money sent back to home countries by people working in a foreign land. Import and export of labor service may be undertaken by individuals, or organized by companies or even by states. And this is becoming an important kind of invisible trade for some countries. Invisible trade can be as important to some countries as visible trade is to others. In reality, the kinds of trade nations engage in are varied and complex, often a mixture of visible and invisible trade.

A:visible trade B:invisible trade C:combination of the two D:commodity trade

Questions from 31 to 35 are based on the following passage: Against this background, the WTO faces several daunting challenges. The first is to continue bringing down tariffs on traded goods. Average penalties have fallen steadily since the GATT’s formation but even the most open economies retain lofty barriers: for instance, America still charges a tariff of 14.6% on import of clothing, five times higher than its average levy. Resistance to tariff cuts is strongest in agriculture. According to Tim Josling, a trade expert at Stanford University, tariffs and other barriers on farm goods average a crippling 40% worldwide and create distortions that “destroy huge amounts of value”. A new set of global farm talks is planned to start in 1999. At the least, you might think, these could lock in impressive reforms in Latin America and encourage further watering-down of the European Union’s Common Agricultural Policy. But they will prove difficult: squabbles over agriculture almost sank the Uruguay round.
