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?

Select an option to attempt

Explanation

Statement A is incorrect: The passage clearly says only about half of the emission reduction can come from household behavioural changes. Therefore, household emission reduction alone cannot achieve net-zero carbon.

Statement B is correct: The passage states that governments and companies must provide incentives through supply-side investments to make low-carbon options cheaper so that people adopt low-carbon behaviour.

Statement C is incorrect: The passage mentions making low-carbon options cheaper only as a means to encourage behavioural change, not as the central idea.

Statement D is incorrect: The passage does not specifically mention subsidies for manufacturing industries; it speaks generally about supply-side investments.
