Question

The government announced subsidies for electric vehicles (EVs) to encourage consumers to buy more EVs. However, sales of EVs remained stagnant. Which of the following, if true, would best explain the outcome?

• A. Charging infrastructure for EVs remains inadequate
• B. EV manufacturers released new affordable models
• C. Petrol prices fell marginally during the period
• D. Public awareness about EVs increased significantly

Hint:

For cause-explanation questions, identify factors that could logically explain why an expected effect did not occur.

Answer 1

The Correct Option is A

Step 1: Analyze problem — Subsidies intended to increase EV purchases did not work.
Step 2: Identify explanatory factor — Barriers preventing uptake despite subsidies would explain stagnant sales.
Step 3: Evaluate options — (a) identifies a key practical barrier (lack of charging infrastructure). Other options would increase sales, not explain stagnation.
Step 4: Conclusion — Option (a) is correct.
