Query regarding "who" and subject identification

[dvrsrikar]

Hello Ron / Stacey

I had posted these question on a thread before but havnt gotten any reply - my exam is day after so it will be great if you can ans these:

Can you pls explain what/who is the subject of this sentence:
"Less than 35 years after the release of African honeybees outside Sao Paulo, Brazil, their descendants, popularly known as killer bees had migrated as far north as Southern Texas." ?

Am trying to understand whether the subject is "the release of African honeybees" or "honeybees"?

I was also wondering whether "who" can only be used for Singular and Living - can "who", for example, refer to "tribes" (Nonliving and plural)?

Thanking you in advance...and awaiting your response (hope the sentence is correct parallelism) :)

Thanks a ton!

Hey DVR, sorry that we didn't get to this before your exam. Did the earlier thread get answered in time?

In any case, please include the entire question, and verify that it's a GMAT Prep question. The sentence as you've recorded it can't be quite right; it needs a comma after killer bees.

OK, now to answer your question. The core of this sentence is descendants... had migrated, so the subject is descendants.
