根据下面内容，回答题： Coffee is worth approximately $ 50-60bn per annum in terms of world sales. It is a truly international commodity， and today more than 50 countries in the world grow coffee beans. （0）________13 ICO consists of61 governments， 43 of which are exporters and 18 of which are importers. The organi- zation helps coffee producers and promotes coffee consumption worldwide. ICO esti- mates that world production next year will reach 97. 5 million bags， ll. 3 million bags higher than the current year. （8）________ As the largest producing country， Brazil is par- ticularly important in the coffee world. In1994 Brazil was responsible for 25% of world production， Colombia was next with13.4%， Indonesia had 7.5%， Mexico4. 7%， Guatemala 3.8% and Ethiopia and Vietnam were equal with 3.4%. Coffee is a tough crop， and can be grown in areas where it is difficult or impossible to grow other crops. （ 9 ）________ However， disease is always a problem for coffee production， as we can see in some parts of South America at the moment. ICO is active in educating farmers about avoiding disease and dealing with problems when they occur. The distribution chain varies from country to country， explains Pablo Dubois. In most countries the smaller farmers sell their crop to a local trader， who then sells it on to ex- porters. There are， however， other distribu- tion systems. （ 10 ）________ Some countries， like Vietnam， have special government mar- keting organizations for coffee. Coffee prices often vary greatly from one year to the next. In 1997， for example there was a large rise in the world price， which was immediately felt by the consumer. Rising prices always result in a drop in sales， which will have a bad effect on those developing countries which are highly dependent on foreign exchange from coffee exports. （ 11 ）________ In the opinion of Pablo Dubois， the biggest problem for his organization is to create greater consumer awareness of the different varieties of coffee and different ways of preparing it. （ 12 ） ________ICO is therefore concentrating its promotional activities on Russia and China. It is also encouraging environmentally friendly coffee production， and last year's seminar on coffee and the environment created a lot of interest. The future looks bright for the coffee industry. It is estimated that consumption over the next few years will continue to rise steadily. New markets like Eastern Europe and China are expected to develop fast.
