For centuries there have been descriptions of unusual animal behavior happening before and related to earthquakes. In cases where animals show unusual behavior some tens of seconds before a quake, it has been suggested they are responding to the P-waves. These travel through the ground about twice as fast as the S-waves that cause most severe shaking. They predict not the earthquake itself-that has already happened- but only the possible arrival of the more destructive S-waves.
The word "they" refers to ..... .
1) P-waves
2) animals
To me, #1 is the best. But I think it's another question that I would call "subjective", rather than "objective".
The preceding sentence is talking about P-waves, even using a pronoun to do so. In addition, nothing redirects our attention back to the animals. Therefore, I think #1 is the best answer.
Also, P-waves is followed by the pronoun these, which clearly refers to P-waves. The next sentence begins with they, which again ties together with P-waves" and "these." As a reader, that's what I understand.
I want to explain the answer to my students. Let me know what you think here.
Thanks.
I agree with you, but consider this. The writer says 'They predict . '.

I agree with you, but consider this.
The writer says 'They predict . . '. Do you think inanimate things can predict? Or can only living creatures predict?
I think the writer could have expressed his meaning more clearly. Perhaps you could ask your class to try a rewrite?
No, I think the writer intends 'they' to refer to the P-waves. I just don't think 'predict' is a good word to use, as it suggests 'animals'. A quick fix is to reiterate the noun instead of using a pronoun.
