Answer:
Have you been attending PTA meetings yourself? Have you been helping them with their current projects? If not, then you might not get much traction. If I’m the head of a volunteer organization, and my first communication with you is a letter telling me what I’m supposed to help you with, I’m probably not going to jump right to it.
You are more likely to get help if you participate in PTA meetings and activities, and talk one-on-one with other members about the issues that concern you.

I think the questions that must be ask are:
a.What does “encryption” mean?
d.What are “key distribution problems”?
All the text is based on the concept "encryption" so it is very important to know what it means in order to undestand the rest of the information. If not, you will be missing important facts. In addition, there are a lot of words used that are derived from this one, so you won't be able to undestand them.
Another important concept that gives a lot of information just by knowing it's meaning is "key distribution problems", they could be two or a thousand, it is important to know what they are and what they do.
The other question that seems important is the one of the "public key cryphtography" but this one can be inferred by the context.
