There is also a split between the use of digging and dig.
When we see that we need to choose between a phrase that starts with a noun or one that starts with a preposition, we should always begin by looking at the non-underlined portion of the sentence. The sentence begins “The curator of the museum is eager to examine.” “Examine” is a transitive verb, which means it must have an object. A prepositional phrase cannot be the object of a verb. An object is always a noun or pronoun or, in some cases, a noun clause. Options A, B, C, and E all start with a preposition (on, about, into, and on, respectively), and a preposition cannot immediately follow a transitive verb.
This means the only possible correct answer is Option D.And just in case that seems a little too easy, we’ll quickly review some other issues with the incorrect answer options. Option A uses “at the site in Peru while they were digging.” This is wordy and redundant, and other options offer more concise ways of saying the same thing.
Option E makes it hard to tell if the phrase “found while at the dig site in Peru” is modifying “archeologists,” which would mean the archeologists were found at the dig site, and that makes no sense. An argument could be made, though it would be poor placement, that it is modifying artifacts, but then it would mean the artifacts were found while they were at the dig site in Peru, implying that sometimes the artifacts were at other dig sites. That is also nonsensical.
Option B could be clearer, because you could infer that the artifacts were found while the artifacts were digging in Peru. That is definitely illogical.
Now, this narrows our answer choices down to two, and once again, we’re left needing to simply know that transitive verbs are not followed by prepositions.
Option D is best answer.
