Answers for”Sticking back at lightning with lasers” with explanations

Question 1-3:

1. D
2. A (elimination method)
3. A (para 3, line 6-8: ―University of Florida, with support from the Electrical Power
Research Institute [EPRl), based in California. EPRI, which is funded by power
companies, is looking at ways to protect the United States‖
para 5, line 3-4: ―of the University of New Mexico. Diels is leading a project,
which is backed by EPRI, to try to use lasers to discharge lightning safely‖)

Question 4-6:
4. power companies (para 3, line 7-8: ―Institute [EPRl), based in California. EPRI,
which is funded by power companies, is looking at ways to protect the United
States]

5. safely (para 5, line 4-5: ―backed by EPRI, to try to use lasers to discharge lightning
safely and safety is a basic requirement since no one wants to put themselves‖)

6. size (para 7, line 2-3: ―portable: it‘s a monster that takes up a whole room. Diels is
trying to cut down the size and says that a laser around the size of a small table is in
the offing‖)

Question 7-10:

7. B – atoms

8. C – storms clouds
(para 6, line 2-4: ―revealing their ability to extract electrons out of atoms and create
ions. If a laser could generate a line of ionisation in the air all the way up to a storm
cloud, this conducting path could be used to guide‖)

9. G – rockets (para 5, first 3 lines: ―And anyway, who would want to fire streams of
rockets in a populated area? ‗What goses up must come down,‘ points out JeanClaude Diels of the University of New Mexico.‖)

10. D – mirrors (para 6, line 8-9: ―Instead it would be directed at a mirror, and from there
into the sky. The mirror would be protected by placing lightning conductors close
by.‖)

Question 11-13:
11. NO (para 8, line 2-3: ―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‖)

12. YES (para 8, line 5-6: ―money yet, but I‘m working on it,‘ says Bernstein. He reckons
that the forthcoming field tests will be the turning point — and he‘s hoping for good
news‖)

13. NOT GIVEN
