HOTS English Primary 4 Comprehension

Read the passage and answer the question.\n\nIn 2019, the Singapore government announced that it would phase out petrol and diesel cars by 2040, replacing them with electric vehicles (EVs). EVs produce zero tailpipe emissions, which helps improve air quality in cities. However, critics point out that if the electricity used to charge EVs comes from coal-fired power stations, the overall carbon footprint may not be significantly reduced. Singapore currently generates most of its electricity from natural gas, which produces less carbon than coal but is still a fossil fuel.\n\nIs the following statement TRUE or FALSE?\n"Switching to electric vehicles will definitely solve Singapore's carbon emission problems completely."

A True — EVs produce no emissions at all.
B True — Singapore's electricity is fully renewable.
C False — EVs still depend on the energy source used to generate electricity.
D False — EVs are more expensive so few people will buy them.

Worked Solution

Step 1: Identify the claim: switching to EVs will DEFINITELY solve ALL carbon emission problems. Step 2: The passage says EVs have zero tailpipe emissions but notes that if electricity comes from coal or fossil fuels, overall carbon may not be significantly reduced. Step 3: The word "definitely" and "completely" make the statement an overstatement. The passage presents conditions under which EVs may not fully solve the problem. Step 4: The correct verdict is FALSE, and the reason must come from the passage — EVs depend on the energy source used to generate electricity. Answer: False — EVs still depend on the energy source used to generate electricity.

Correct answer: False — EVs still depend on the energy source used to generate electricity.
