Complete the passage with the correct form of the words in capitals.

Gandhi once said. “Oh, my fallow men, do not defile your bodies with (1)  (SIN) foods.” Could he have been talking about GM food? Genetically modified food promises to wipe out disease and famine. However, there is great controversy regarding the human health risks and the potential environmental impact.

There are certain advantages to GM foods. One argument in their favor is that GM crops are altered to (2)  (STAND) disease and pests, while offering improved flavor, better quality, and longer shelf life. Thus, more crops can be grown and more (3)  (NURTURE) are added allowing healthier products to reach the public. Secondly. their stronger resistance means that fewer chemicals and (4)  (PEST) are needed. Needless to say. fewer chemicals means less (5)  (TOXIC) will enter local waters.

However, there are also many (6)  (DRAW) to GM foods. Opponents argue that not enough research has been conducted on the safety of these products. For example, they claim that there are no guarantees that GM foods are safe for the human body. It is feared that eating GM products will alter the genetic (7)  (MAKE) of man. It is also argued that GM crops may threaten (8)  (DIVERSE) by decreasing the richness and variety of food. For instance, some argue that by tampering with nature all (9)  (ORGAN) might lose their original values which might result in the loss of certain flora and fauna.

In conclusion, I believe that although advances in modem science are (10)  (PASS) our wildest dreams, new products should be strictly screened for safely. We need to be aware of any of the potentially harmful consequences before allowing a genetically modified crop into the food chain.

Here’s a(n) (1) thought. Of the between 10 and 100 trillion cells that make up the human body, most of them are not even human. In other words, it you had to count all the cells in your body, the vast majority – by a factor of ten – would be microbes. These (2) creatures which, when magnified, look like horror movie monsters, are everywhere – on your eyeballs, in your mouth, your nose, your ears, and all over your skin. There are up to a hundred trillion (3)  in the human intestine alone.

Strangely enough, scientists do not yet know the (4) of most of these microbes. They have, however, come to the conclusion that each one of us hosts somewhere between 500 and 1,000 species of microbes, (5) about 8,000 (6) . This internal multitude varies so distinctly from person to person that it can serve as a kind of (7)  of an individual.

What is clear is that most of the microbes are not (8) . Rather, they are so vital for our (9) that some researchers consider them an organ of the human body. A human body is like a complex (10)  – a biosphere, almost. Different species follow their own (11) , but collectively they advance the cause of the whole. Gut microbes, for instance, perform some (12) functions such as helping to digest food, (13) poisons, producing vitamins, and warding off disease.

This symbiosis, or strategic (14) between mammals and microbes – that goes back millions of years – has led some scientists to believe that we will never fully understand the (15) of our bodies until we understand the microbes that live in them, too. By probing further into these rarely studied ‘alien communities’, they may be able to discover cures for everything from illness to obesity.
