Someone will be glad to check your answers.
I don't know Spanish, but I do know that subjects and verbs must "match" -- that is, if you have a first person singular subject, you'd better have the right singular verb form to match it.

Study what these terms mean, and then apply them to your sentences.

first person singular
first person plural
second person singular
second person plural
third person singular
third person plural
Can you please tell me the answers and how to explain it
