Fill in the blank (5) with the appropriate word from the options below:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. collaborate.
The most appropriate word to fill is "collaborate" because it means working together, which fits the context of society coming together to address climate change.
The other options, such as "colonize" (to control an area), "congregate" (to gather), and "commemorate" (to honor or remember), do not convey the idea of collective action as effectively as "collaborate."
