Exercise 2: YES/ NO/ NOT GIVEN
| Reading passage | Questions | YES/ NO/ NOT GIVEN | |
| 1 | It’s not important, then, if there’s a delay of a few years, or decades, while the human race debates the question of whether to reply and perhaps carefully drafts a reply if a signal from the the universe is received. | If a signal from outer space is received, it will be important to respond promptly. | |
| 2 | Bernstein says that Diels’s system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. | Power companies have given Diels enough money to develop his laser. | |
| 3 | One glaring disadvantage of pesticides’ application is that, while destroying harmful pests, they also wipe out many useful non-targeted organisms, which keep the growth of the pest population in check. This results in what agro-ecologists call the ‘treadmill syndrome’. Because of their tremendous breeding potential and genetic diversity, many pests are known to withstand synthetic chemicals and bear offspring with built-in resistance to pesticides. | A number of pests are now born with an innate immunity to some pesticides. | |
| 4 | When handled by experts, bio-control is safe, non-polluting, and self-dispersing. | Bio-control is free from danger under certain circumstances. | |
| 5 | According to Wagner’s analysis of the Bachia family tree, the toed species re-evolved toes from toeless ancestors and, what is more, digit loss and gain has occurred on more than one occasion over tens of millions of years. | Wagner believes that Bachia lizards with toes had toeless ancestors. | |
| 6 | More recently, however, examples have been reported that break the time limit, suggesting that silent genes may not be the whole story. In a paper published last year, biologist Gunter Wagner of Yale University reported some work on the evolutionary history of a group ofSouth American lizards called Bachia. | Wagner was the first person to do research on South American lizards. | |
| 7 | Nasa notes that a lot of time is spent wondering about and searching for proof of liquid water on Mars, which would be a signal of life. But the new pictures show that the planet itself was once far more alive than it is today – made up of flowing molten lava that spread across its surface. | The photos show that the surface of Mars is more active than ever. |
