Civil Services Examination · Question 41

Read the following passage and answer the item that follows. Your answer should be based solely on the passage. Passage: Over the next 30 years, many countries are promising to move to net-zero carbon, implying that household emissions will have to be cut to close to nothing. A leading climate scientist reckons that, at best, half the reduction might be achieved through demand-side measures, such as behavioural changes by individuals and households. And even that would require companies and governments to provide more incentives to change through supply-side investments to make low-carbon options cheaper and more widely available. Which one of the following statements best reflects the central idea conveyed by the passage?

  1. Moving to net-zero carbon is possible only by the reduction in household emissions.
  2. Low-carbon behaviour in people can be brought about by incentivising them.
  3. Cheaper goods and services can be made available to people by using low-carbon technologies.
  4. Manufacturing industries that use low-carbon technologies should be provided with subsidies.
