Translation:These objects are quite difficult to obtain.
It's an adjective in this case. Or rather, "difficult to obtain" is the adjective phrase. ("Assez" is an adverb modifying that phrase, and you can leave it out to see the rest of the sentence more clearly.) "Ces objets sont difficiles a obtenir" has the same structure as "Ces objets sont rouges", except the adjective is a phrase. Anyway, it still has to agree with "objets."
'Things' would be a more usual term than 'objects' in everyday English but things not accepted today, November 3, 2018
This is purely subjective but "somewhat", like "fairly", feels a bit light for explaining how difficult it is to obtain those objects. "They are quite difficult to obtain" indicates a rather high degree and "somewhat" suggests that they are just "slightly difficult". IMO
I don't agree, I would say fairly and quite are pretty much the same in this context
I noticed in your explanation you used "rather high degree" to explain the level of difficulty, so why was it marked wrong when i translated ASSEZ to mean RATHER?
Hello, do you know why "difficile" is at plural? In this case it is an adverb and not an adjective for the objects noun.
I would like to know why it is " a obtenir " when " obtenir " already means " to obtain " ?

It's like a passive voice usage. When you use it in another way, you don't have to add à
We want to say something. Nous voulons dire quelque choses
We have something to say. Nous avons quelques choses à dire
So in a different exercise assez had the sense of enough, rather than quite. So, how would one say These objects are difficult enough to obtain?
I put "These things are so hard to get", which was not accepted. Duo's suggested translation was "These objects are quite difficult to obtain". At least in my usage, these statements mean the same thing, albeit at different levels of formality.
"These objects are fairly difficult to obtain." should also be accepted as quite = fairly in this context
I have heard that the intensity level of the adverbs, quite and rather, is opposite in British and American English. In the latter, quite is closer to "very" and rather is "sort of". So is the meaning of "assez" ' closer to very or sort of?
