3.how would you express "they will tell" in latin
nuntiabant
nuntiant
nuntiabunt
nuntiabitis
7. identify the tense "she will love"
perfect
imperfect
future
present
8. identify the tense "he is loving"
present
imperfect
future
perfect
10. best translation "vocabat"
he will call
she called
they were calling
they do call

3. Nuntiabunt is the third-person plural future indicative (they will tell) of nuntio (I tell).
7. She will love is the future tense. 
8. He is loving is the present tense. It is actually a special type of present tense called present progressive, which serves to distinguish "he is loving" from "he loves." 
10. vocabat is the third-person plural imperfect indicative of voco (I call). She called is the best translation of the options given, but I would say "she was calling" is more accurate. This is because imperfect has the implication of a continuous or uncompleted action that happened in the past, and "called" does not have this meaning in English. However, as I said, "she called" is the best option of those given. 

I hope I was helpful!
