Kaplan Question Doubt

The late Japanese mathematician Shizuo Kakutani developed mathematical tools used for disparate purposes including proving the existence of Nash equilibria, accurate description of random processes such as coin-flipping, and the furthering of economists' understanding of supply and demand in a complex economy.

I have this doubt that is very basic but important.
This sentence is about very basic rules of parallelism. Here to get this correct, one just needs to make sure that the three items in the list are parallel.
My doubt emerges when I saw, in this sentence, two rather than three items that need to be parallel.
So,I saw the following items that need be parallel.
1.proving the existence of Nash equilibria
2.the furthering of economists' understanding of supply and demand in a complex economy.


and the middle item, accurate description of random processes such as coin-flipping as modifying the 1 above.

How does one make sure that the items that need to be parallel are three rather than two items and one modifying the 1st one ?

Basically, what helps you decide in such a case is logical connection between the items and the meaning of the whole sentence. The listed items should all be not only grammatically but also logically parallel. Obviously it might be sometimes very challenging to decide whether they fit together.

What made you think that the middle item modifies the first?

I just thought that the middle element is describing the Nash Equilibria

Also, in one of my previous posts in which you had replied, I had a follow up question.
Can pronoun refer to the noun in a prepositional phrase as its antecedent ?
For ex:
The popularity of cricket is well known, inspite of the fact that a few nations don't play it at all.

Can it refer to cricket here, given that cricket is in a prepositional phrase ?

If you can, please answer my previous post where you had replied.
Thanks.
