Underlined part need a verb form for conclude,

A & B - Eliminate based on concluding
C - Correct
D - passing through and would ..incorrect
E - having concluded - incorrect; the atom to be - incorrect

Official Explanation


Split #1: Right at the beginning, we have "Rutherford, concluding" (noun + modifier) vs. "Rutherford concluded" (noun + verb). Everything before the name Rutherford is fluff. Rutherford is the subject. We get "concluding/concluded", and everything after the "that" is what he concluded. The sentence needs a main verb: the action of Rutherford must be the main verb of the sentence. If we choose "concluding" or "having concluded", the participles, then the sentence overall has no verb --- this is the famous missing verb mistake. We need a verb here. Choices (C) & (D) correctly have the verb "concluded", and the other three have the participles, so they are incorrect.

Split #2: "because"/"since" --- both are correct. This is a false split.

We have two subordinate clauses --- the "because"/"since" clause nested inside the "that" clause.

Split #3: the "because"/"since" clause needs a bonafide [noun] + [verb] structure. The subject in all five choices is "most of the alpha particles", and four the choices have the verb "passed." Choice (D) has the participle "passing", so this clause lacks a true verb. Choice (D) is incorrect.

Split #4: in the "that" clause, the subject is "most of the volume", and there's a good deal of variation in the final verb at the very end of the underlined section:

(A) "was" --- acceptable

(B) "would be" --- strangely hypothetical, not appropriate

(C) "had to be" --- very clear and strong

(D) "would have to be" --- also strong

(E) "to be" --- lacks a verb = wrong

On the basis of all these splits, we see that the best answer, the only answer with no flaws, is (C).
