Questions & Answers about J'offre un échange parce que la qualité est mauvaise.
Wait, offrir is an -ir verb. Why does it end in -e like an -er verb here?
Even though offrir ends in -ir, it belongs to a small group of verbs (along with ouvrir and souffrir) that are conjugated exactly like regular -er verbs in the present tense. That is why it is j'offre.
Why use parce que here instead of à cause de?
How would I turn this into an indirect question, like 'He asks why I offer an exchange'?
Using what we are learning about reported speech, you would replace the explanation with an indirect question and say Il demande pourquoi j'offre un échange. Notice that you do not need to invert the subject and verb after pourquoi; the word order stays exactly like a normal statement.
