(C) more for the reason that it was
(D) the more so for the reason because it was
(E) the reason of it being more so is that it was
Meaning is crucial to solving this problem:Understanding the intended meaning is key to solving this question; the intended meaning of the crucial part of this sentence is that the Hiss case became the political cause of an era, and an additional reason why it did so was that it was the first time a congressional hearing was shown on television.
Concepts tested here: Meaning + Comparisons + Idioms + Awkwardness/Redundancy• "more" and "less" must have a logical sequence with "than"; in a comparison, "more/less...than" is the idiomatic construction.
• "more so" is an idiomatic construction used to convey why a particular characteristic applies to a greater degree.
A: This answer choice uses the phrase "the more so because", conveying the intended meaning - that the Hiss case became the political cause of an era, and an additional reason why it did so was that it was the first time a congressional hearing was shown on television; remember, "more so" is an idiomatic construction used to convey why a particular characteristic applies to a greater degree. Further, Option A is free of any awkwardness or redundancy.
B: This answer choice alters the meaning of the sentence through the phrase "more for its being"; the construction of this phrase leads to an incoherent meaning because it presents an incomplete comparison; remember, "more" and "less" must have a logical sequence with "than"; in a comparison, "more/less...than" is the idiomatic construction.
C: Trap. This answer choice alters the meaning of the sentence through the phrase "more for the reason that it was"; the construction of this phrase leads to an incoherent meaning because it presents an incomplete comparison; remember, "more" and "less" must have a logical sequence with "than"; in a comparison, "more/less...than" is the idiomatic construction. Further, Option C uses the needlessly wordy phrase "for the reason that it was", leading to awkwardness and redundancy.
D: This answer choice uses the redundant phrase "for the reason because it was", rendering it awkward and needlessly wordy; this usage is redundant because "for the reason" and "because" convey the same meaning.
E: This answer choice uses the needlessly wordy phrase "the reason of it being...is that it was", leading to awkwardness and redundancy.
Hence, A is the best answer choice.All the best!
