If 70 percent of 8-year-olds could pass a particular test, then 29 on the test represented an 8-year-old’s level of intelligence.
答案：(A) success
success on the test 指「在該測驗上取得的成功」，是前半條件句 could pass a particular test 的同義改寫；objection（反對）、agreement（同意）、discovery（發現）與通過測驗都無關。
四個都是名詞。你會用中文句意理解：前面說「如果七成的八歲孩子考得過某項測驗」，後面說「就代表八歲孩子的智力程度」，中間填「發現」、填「同意」好像都說得通。問題出在切的位置：
success on | the test
success | on the test
切在上面那一種，就得去找後面接 on 的名詞，四個都不接。要切的是下面那一種：his performance on the test、her score on the test 也都成立，on the test 不是 success 帶的。切對之後只剩一層。前半寫 If 70 percent of 8-year-olds could pass a particular test，後半講的是同一件事——英文不重複用字，同一個概念回來時會換一個說法，pass a particular test 換成名詞就是 success。另外三個都是憑空冒出來的新資訊。一句記完：Wei-ming's success on the civil service exam surprised no one who had watched him study every night after work.（偉明在公職考試上的過關，並沒有讓看過他每天下班後苦讀的人感到意外。）〔情境取材自 105 指考作文題：碩士考清潔隊員〕
objection（反對）：配 to，而且文中沒有任何人反對。agreement（同意、協議）：配 with 某人或 on 某事，一份測驗不是協商的對象。discovery（發現）：配 of，而且比奈在這裡是建立一套標準，不是宣布新發現。objection、agreement、discovery 各自搭 to、on、of，那是名詞自己的介系詞；本題的 on the test 不是這一種，用介系詞刷不掉選項。判得掉它們的是語意——文中沒有人反對，一份測驗不是協商的對象，比奈在這裡也不是宣布新發現。同義記一組：success on the test 等於 passing the test，反過來是 failure（失敗）。
success on a test（測驗過關）、succeed in + V-ing（成功做到）、be successful in（在…上有成就）、objection to（對…的反對）、agreement on（對…的共識）、discovery of（對…的發現）、pass a test（考過測驗）、a level of intelligence（智力程度）。其中 succeed in + V-ing 這一組考過 3 個年度，87 年第 24 題 →、學測詞彙 96 年第 7 題都出現過。
French psychologist Alfred Binet (1859-1911) took a different approach from most other psychologists of his day: He was interested in the workings of the 26 mind rather than the nature of mental illness. He wanted to find a way to measure the ability to think and reason, apart from education in any particular field.
In 1905 he developed a test in which he 27 children do tasks such as follow commands, copy patterns, name objects, and put things in order or arrange them properly. He later created a standard of measuring children's intelligence 28 the data he had collected from the French children he studied. If 70 percent of 8-year-olds could pass a particular test, then 29 on the test represented an 8-year-old's level of intelligence.
From Binet's work, the phrase "intelligence quotient" ("IQ") entered the English vocabulary. The IQ is the ratio of "mental age" to chronological age times 100, with 100 30 the average. So, an 8-year-old who passes the 10-year-old's test would have an IQ of 10/8 times 100, or 125.
