Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. when.
- The sentence discusses people's belief in animals having a sixth sense and their ability to predict when the earth is going to shake, referring to earthquakes.
- The word "when" is an interrogative adverb used to inquire about the time of an event or action.
- In this context, it is used to ask about the specific timing of the earthquake prediction.
- The sentence is framed as a statement rather than a direct question, but the presence of "know" and the context suggest that it is implicitly asking about the timing of the animals' awareness of earthquakes.
