Hello pineda08,
I'm not completely sure that I understand your question.
In question 1 the answer is 'keeps eating' because the subject is 'he', which is a third-person form and so the verb ends in 's'.
In question 4 the answer is 'keep talking' because the subject is 'you', which is a second-person form and so the verb does not end in 's'.
