Read the following article and select the best answer. Article: "Any time! Any where! Decades ago there was no such thing" - "Communication". Then, September 7th 1987, the global system for mobile communication or GSM was born. And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry. To be honest, the world's first mobiles were not so attractive and the range of effectiveness wasn't very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work. There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that's not all. 20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet. "The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute." Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you. Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine. Question: What does the writer feel about the GSM development in the following 20 years? - Satisfied. - Worried. - Confident. - Confused.
Confident.

His mother's ancestors were early settlers in Texas, and over the generations had acquired a 25,000 acre farm at Cotulla. Jeffrey spent most summers of his youth working with his grandfather on their farm. Jeffrey showed intense and varied scientific interests at an early age.

*Question*
Read the following article and select the best answer. Article: Increasingly, over the past ten years, people--- especially young people -have become aware of the need to change their eating habits, because much of the food they eat, especially processed food , is not good for the health. As a result, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers , widely used in farming today. Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple words, this means that the soil has been nourished(...) by unused vegetable matter, which provides it with vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount--but not the quality--of foods grown in commercial farming area. Natural foods also include animals which have been allowed to feed move freely in healthy pastures . Compare this with what happens in the mass production of poultry :there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins. There are other sides of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar. This is actually unnecessary food. It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form of calories. There are no vitamins in it, no minerals, and no fibre. Question: According to the passage, _ . - people can only find sugar to give them energy - sugar is bad for the health - the use of sugar is habit forming - sugar only sweetens food, but provides us with nothing useful
**Answer**
the use of sugar is habit forming
