答案及解析：

　　1. b

　　Solution explanation

　　Sentence 1 describes the "technical vocabulary" and its use. since sentence 2 is also referring to the" vocabulary and jargon", using "such" articulates that connection and makes the reference clear.

　　Hence answer option b is correct.

　　2. c

　　Solution explanation

　　The tense of the verb used before the word "occupied" should be changed. using the verb tense "had occupied" implies that farming and fishing do not still employ great numbers of men, which is inaccurate. we know that farming and fishing still occupy large numbers of people today, therefore the verb tense "have occupied" is more appropriate; it implies that that is has been the case in the past and is still the case today. therefore, answer option c is the best answer to the sentence 6. other options a, b, d, and e are irrelevant.

　　3. e

　　Solution explanation

　　The underlined portion of the sentence is talking about four different professions. therefore, using "their" is more appropriate compared to "his".

　　Given sentence also has two clauses "the lawyer,....with his fellow creatures" and "not meeting them in a merely professional way". these two clauses are not contradictory to each other.

　　Hence, using "but" is not appropriate.

　　Answer choice e connects the two parts of the sentence with continuity. therefore, option e is the correct answer.

　　4. b

　　Solution explanation

　　The sentence 10 would make the most sense if placed after sentence 11.

　　Sentence 10 says "every vocation possesses a large body of technical terms" and sentence 11 says "the proportion has been much increased". therefore, sentence 11 refers to "large body of technical terms" in sentence 10.

　　So, the option b is the right answer. options a, c, d, and e are wrong.

　　5. c

　　Solution explanation

　　Sentence 13 talks about "newly developed words, which were not part of literature" and the last paragraph gives details about various professions. therefore, the sentence should connect "newly developed words" or "literature" to "professions".

　　Out of all options, option c is the correct answer.

　　Option a is an ambiguous statement.

　　Option b or d have completely unrelated meanings. therefore, they are wrong.

　　Although option e incorporates "literature" and "profession", it does not act as a connecting statement.

　　Hence, option c is the correct answer.
