题目：
The following questions present a sentence, part of which or all of which is underlined. Beneath the sentence, you will find five ways of phrasing the underlined part. The first of these repeats the original; the other four are different. If you think the original is best, choose the first answer; otherwise choose one of the others.
These questions test correctness and effectiveness of expression. In choosing your answer, follow the requirements of standard written English; that is, pay attention to grammar, choice of words, and sentence construction. Choose the answer that produces the most effective sentence; this answer should be clear and exact, without awkwardness, ambiguity, redundancy, or grammatical error.
The combat code of medieval knights resembled that of Japanese samurai and therefore, had they faced firearms in combat, would most likely have reacted in a similar manner to the Japanese samurai of the Meiji Revolution.（）
A. The combat code of medieval knights resembled that of Japanese samurai
B. Medieval knights upheld a combat code that resembled the combat codes of Japanese samurai
C. Medieval knights upheld a combat code resembling that of Japanese samurai
D. Medieval knights’ upholding of a combat code resembling that of Japanese samurai
E. The medieval knight’s combat code resembled that of Japanese samurai
答案：
参考答案：C
解析：
The latter half of the sentence demands that "knights," not "combat code," be the subject of the underlined clause, so answers A, D, and E are out. Between B and C, C is preferable because it is more succinct, and because B creates a possible confusion in its reference to a single "combat code" for medieval knights but multiple "combat codes" for Japanese samurai.
