Translate into English, and if you still don't understand the question, then please repost.

that's exactly what i need help on doing

Due to the number of postings that you have on Spanish, it seems that you are at the wrong level to make these translations. Request to go back a level; otherwise, help from this site may decrease. Overall this loosely translates as follows in English -

Would you show your Ana and Paco tocacintas new? Yes, I _____ them and theirs too.
a. show
b. sample
c. showed
d. showed

c and d are the same?

Translation: Did you show Ann and Frank your new tapeplayer? Yes, and they ____ me theirs.

a. they are showing/they do show/they show (Present tense)
b. he/she/you show/do(es) show, is (are) showing (Present tense)
c. they did show , they showed (Past tense)
d. he/she/you did show/showed

Now, look at the question itself. Was that Preent or Past tense and who woul d be the subject?

Sra

To a point yes. They are both past forms of show but one is group ownership translating as they showed while the other translates as it showed. Remember the basic rule of spanish on translations and the difference in which is which should come to you.

got it, thanks Sra!
