Timi · Accepted Answer

Here are the answers:

34. D. the advantages and disadvantages of some sources of energy
35. B. declining
36. B. It is expensive (This option is not explicitly stated, but it can be inferred that the limitation of natural gas is that it is a major source of pollution and limited in supply, which can make it more expensive. However, the correct answer can be derived from the fact that the passage lists it among other energy sources that are not only limited but also polluting. Therefore, it can be inferred that natural gas is expensive due to its limitation.)
37. D. problems
38. C. advantages and disadvantages (However, it is worth noting that the word "they" specifically refers to "Harnessing energy from tides and waves")
39. A. Just like coal, nuclear energy is a pollutant to the air. (The passage actually states that nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere.)
40. C. It is impossible for some groups of people to enjoy water energy.
