Hello. I may have some ideas, I'll try to give some hints.
Have you solved and/or analyzed similar questions before?
What have you attempted so far regarding question 1?
Have you figured out which words in the syntax diagram that are allowed as the first word in the sentence?

Depending on your answers I'll try to provide relevant hints in the right direction.

It depends. What backgroud skills do you have? Some programming? 

Personally i learned the details in a compiler tech cource but that is not needed for this task.

Are you familiar with syntax diagrams? https://en.wikipedia.org/wiki/Syntax_diagram

have you studied some algorithms, for instance how a simple parser works?

 

(Wikipedia may not be the best source for studying but a good place to start, so we can find out where to take the discussion)
