^ 7. E is fine because it's an appositive phrase modifying "Nobel Prize for literature." This is not a run-on sentence; it's simply providing more information about the Nobel Prize.
19. A is wrong because "which" begins a relative clause, but it doesn't modify any specific noun (it's trying to modify an implied word, "situation," but it's not there, so "which" is being used incorrectly). Note that the two nouns in the main clause are plural, and "which makes" is singular (and it would only be modifying "resources", anyway). To make the sentence grammatical, the noun "situation" (or something equivalent) must be inserted.
32. Yep, it's "any other century."
