Guys, I am really confused when I get a question on parallelism. I am able to eliminate three choices; however, I am confused between the choice having verb+ing and the choice having to+verb. I really don't understand how to approach such questions. Please help me on this.

For example :
Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.

A new study suggests that the conversational pace of everyday life may be so brisk it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make sense of speech.

What am I missing to understand? How should I approach such Questions?

The first question is using a verb-ing modifier

“Could alter the salinate content of ...” robbing.

The other question is using the word ability

As an idiom it is ability to verb

So it has to be ability to distinguish.

I hope this helps.
