Read the passage and choose one correct answer for each question.

People have been hunting whales for at least a thousand years, and there were

no real problems until 20

^th

century. What happened was that fishing technology

became much more efficient and the ships were much faster, so more and more

whales were caught. In the 1960s the main whaling countries were killing more

than sixty thousand whales a year, and everyone began to realize that something

had to be done.

It was environmental groups like Greenpeace that really made things change.

They set out to make people aware of the fact that whales were fast becoming

extinct. But even now we don’t know if all this interest has become too late. Let’s

take the great blue whale for example, which at thirty to forty metres long is the

biggest animal there has ever been – now there are perhaps about two thousand or

so left. In fact they have been protected for quite a long time, but there is no sign

that the population is growing.
