Show answer & explanation
Correct answer: A
Explanation
The correct answer is: Only I and II are implicit.
Assumption I is implicit: The statement states that investment in renewable energy should be made to combat climate change. The speaker would only say this if they believed that renewable energy has the potential to mitigate the effects of climate change. Therefore, this assumption is completely correct.
Assumption II is implicit: When governments are advised to "tackle" a problem and "invest" in it, the underlying idea is that the problem is serious and requires immediate action. Therefore, this assumption is also implicit.
Assumption III is not implicit: This assumption is too harsh or extreme because it requires "all energy sources" to be renewable. The statement only talks about investing in renewable energy; it does not say that 100% of the world's energy sources must be replaced immediately or that doing so is mandatory.
