Supernovas destroy their immediate environments in vast explosions, BUT by synthesizing heavy chemical elements, THEY provide the universe with the possibility of biochemistry-based life as we know it.

In the explanation, it says that "THEY" clearly refers to supernovas. Why is there not an ambiguity of antecedent between - supernovas and explosions.
Is it just due to the modifier " by synthesizing heavy chemical elements"

An antecedent cannot be a noun in a preposition, and if you look "explosions" is part of the phrase "in vast explosions". Good question!

Hi, I am new here, and just starting up with the GMAT.
And after looking at this example and the explanation, I understand why "explosions" is not an antecedent but i couldn't figure out why "environments" can't be antecedent for "THEY".

Please explain.

_____ provide the universe with the possibility of biochemistry-based life as we know it.

Supernovas provide the universe with the possibility of biochemistry-based life as we know it.

Supernovas' environments cannot provide the universe with the possibility of biochemistry-based life as we know it.


So, In case its a good idea to replace the pronoun with multiple antecedents and see which one makes sense. Here " Supernovas" make sense and moreover it it the focus of the sentence . Hence it wins clearly.

That is a very good point, and a nice way to work out pronoun antecedents. :-)
