Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Therefore.
Context: The sentence concludes that animals might still sense events based on earlier discussion. We need a word showing a logical conclusion.
Analysis of the given options:
However: Contrast.
Nevertheless: Concession.
Moreover: Addition.
Therefore: Conclusion or result.
Correct word: Therefore
Reason: The connector 'Therefore' is used to introduce a contrasting idea to the one expressed before it. In the previous sentences, the author highlights several reasons why animals might fail to give signs before certain events (like diseases or unpredictability of natural calamities). The word 'Therefore' signals a shift, introducing an exception to this skepticism — that despite the doubts, there is still a possibility animals can sense certain unnatural events.s.
Hence, the chosen option is correct.
