Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.

The word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produces the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.

These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal “arms” or “hands”. Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.

Polar bears are in danger of dying out. (25)_______ some other endangered animals, it's not hunters that are the problem, it's climate change. Since 1979, the ice cap at the Arctic Circle where the polar bears live has reduced in size by about 30 per cent. The temperature in the Arctic has slowly been rising and this is (26) _______  the sea ice to melt, endangering the polar bears' home. The polar bears' main sources of food are the different types of seals found in the Arctic. They catch them by waiting next to the air holes seals have made in the ice. (27) _______  the bears are very strong swimmers, they could never catch seals in water. This means that the bears really do rely on the ice to hunt. Polar bears also need sea ice to travel. They can cover a huge territory and often swim from one part of the ice to another. They have been (28) _______  to swim up to 100 km, but when there is less ice, they may have to swim further and this can (29) _______  fatal to the bears. A number of bears have drown in the last few years and scientists believe that it is because they were not able to reach more ice before they became too tired and couldn't swim any further.
