In the following question, an incomplete statement followed by fillers is given. Pick out the best filler to complete the incomplete statement, correctly and meaningfully. Due to the rising fuel prices, the government has decided to __________.

Explanation: The sentence suggests that the government is responding to rising fuel prices. The best response would be to promote alternative energy solutions, such as electric vehicles, to reduce dependence on fossil fuels. Option (1) contradicts the idea, as reducing taxes would make fuel more affordable rather than addressing price hikes. Option (2) is a direct financial reaction but does not align with a long-term solution. Option (3) is possible but does not necessarily address the root problem of rising prices. Thus, (4) promote the use of electric vehicles is the most appropriate choice.
