Even though the grammar of this sentence is explained and practiced later, I will give you a brief introduction to it here. To understand this sentence, you would first need to notice that there is no verb in the sentence. In Klingon, pronouns can act as verbs equating two things. So 'oH in this sentence is acting like "to be" or more specifically, "it is". The "it" that it is referring to is pongDaj'e' "his name". We don't know who "he" is because Duolingo just gives you the sentence without context, but that is no different than the isolated English sentence, "What is his name?" (By the way, the Klingon does not actually indicate a sexual gender, so it could also be translated as "her name".) We can use this same construction to say what the name is: torgh 'oH pongDaj'e' "His name is Torg." But in this case, the sentence is using the question word nuq "what?". So instead of saying what his name is we are asking what his name is.
I hope that helps.
