Answer:
It as a simple formula to follow in order to do simple senteces such as the ones they ask. Through out the whole assignment you're using the same verb of "gustar"
The formula is:
A + possesive pronouns + singular noun+ "gusta" + verb in present
in negative it is:
A + possesive pronouns + no + singular noun+ "gusta" + verb in present
For example, the last instruction of the first part asks you for a sentence of something someone else does not like to do.
A ellos no les gusta correr.
A + ellos + no + les+ "gusta" + correr
Hope this helped (:
