Fill in the blank (2) with the appropriate word from the options below:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. address.
The most appropriate word to fill is "address" because it means to deal with or discuss something, which fits the context of talking about the causes of climate change.
The other options don't fit as well: "evade" (to avoid) contradicts the intention of discussing the issue, "elaborate" means to provide more details but doesn't fit the context of focusing on the causes, and "overlook" (to ignore) is the opposite of what the sentence aims to convey.
