SAVING THE TIGER

In 1973, when the tiger appeared to be facing extinction, the World Wild Fund for Nature

and the Indian Government agreed to (51)__________ up “Operation Tiger” – a campaign

to save this threatened creature. They started by creating nine special parks so that tigers

(52)__________ live in safety. The first was at Ranthambhore, a region (53)_________

was quickly turning into a desert because too much of the grass was being eaten by the

local people’s cattle. At the time, there (54)_______ just fourteen tigers left there. The

government had to clear twelve small villages, which meant moving nearly 1,000 people

and 10,000 cattle, (55)_____the land could be handed back to nature.

Today, Ranthambhore is a very different place, with grass tall (56)__________ for tigers

to hide in, and there are now at least a hundred of them in the park, wandering freely about.

Other (57)___________ have also benefited. For example, there are many more deer and

monkeys than before. The people who were moved are now living in

(58)

______conditions. They live in new villages away(59)_______ the tiger park,

with schools, temples and fresh water supplies. There are now sixteen such tiger parks in

India and the animal’s future looks(60)_____ little safer.

Read the following passages and choose the correct answer to each question.

Researchers don’t think there’s any question that the discovery of a gene which appears to

be linked to many types of cancer is really exciting and the best news for the public in a

long time. The gene is involved in a high percentage of human cancers and its discovery

might eventually lead to the development of a new anti-cancer treatment.

In normal cells, this gene, named MTS1, acts as a brake during the cell division process.

But the researchers have found that the cell is missing in about half of the tumor cells they

studied, allowing uncontrolled division of cells to take place, and the resulting spread of

the cancer.

This discovery could be exploited in two ways, either by supplying the missing gene

through gene therapy or by copying its function in a drug. Of course, this is not the first

gene to be found that can suppress tumors; in fact it’s the eleventh or twelfth. However,

because of its seemingly wider presence, or absence, the knowledge of its existence could

lead to a cure for some types of cancer.
