As me personally, I would believe that it would be a "desktop publishing" as this kind of publisher would be used to make thing such as a 'newspaper, special paper' such as new letters also, and also perhaps prom cards (as an example) and things practically like this. Based on my information, I believe that your correct answer would then be "<span>desktop publishing".</span>
I think it’s “a” because teachers like when you ask questions. It could also be “b” because teachers also like when you’re independent.
The correct answer would be B. Why? The direct object is David, so not that, them is not included in a prepositional phrase, so it's not an object of a preposition, and David is the subject, and not them. Hope this helps!
Have a fantabulous day! :)
