　　Answer to Question 81

　　To establish the clearest comparison between circumstances in 1973 and those in 1984, a separate clause is

　　171

　　needed to describe each year. Choices A and C, in failing to use separate clauses, are too elliptical and

　　therefore unclear. Choice A also incorrectly uses and and a semicolon to separate an independent clause and a

　　phrase. Choice D incorrectly separates two independent clauses with a comma; moreover, the placement of in

　　1984 is awkward and confusing. In choice E, that refers illogically to income, thereby producing the

　　misstatement that income rather than mortgage payments rose to forty-four percent in 1984. Choice B is best;

　　two properly constructed clauses that clearly express the comparison are separated by a semicolon.

　　Answer to Question 82

　　The logical comparison here is between large steel plants and small mills. Choices A, B, and C illogically

　　contrast large steel plants with [the] processing [of] steel scrap. Further, in choices B and C remaining is

　　not parallel with put; consequently, it is not clear exactly what is remaining economically viable. The contrast

　　between large plants and small mills is logically phrased in choices D and E, but remained in E is not parallel

　　with put. Choice D, the best answer, uses parallel verb forms to complete the construction have been able to

　　put... and remain.

　　Answer to Question 83

　　Only choice C, the best answer, produces a sentence in which every pronoun it refers clearly and logically to the

　　noun condition. In choices A and B, the phrase indicate that there . is one does not grammatically fit with

　　when it is not because it has no referent. Choices B and D are imprecise in saying that a test will fail to detect

　　when a condition is present, since the issue is the presence and not the timing of the condition. Further, its

　　presence in D leaves the it in when it is not without a logical referent: it must refer to condition, not presence.

　　Choice E repeats this error; also, the presence ... when it is there is imprecise and redundant.

　　Answer to Question 84

　　In choice A, the plural pronoun their does not agree in number with the singular noun person. Choices C, D,

　　and E can be faulted for failing to complete the construction One legacy ... is with a noun that matches the noun

　　legacy; these choices use verb forms--the infinitive to realize or the present participle realizing--in place of a

　　noun such as realization. Further, when in C and D is less precise than as in characterizing a prolonged and

　　gradual process such as aging. B is the best answer.

　　Answer to Question 85

　　Choice B is best. In A and D, have grown does not agree with the singular noun market. In addition, all of the

　　choices except B use plural verbs after that, thus illogically stating either that bygone styles of furniture and

　　fixtures, or fixtures alone, are reviving the particular pieces mentioned; it is instead the market for those styles

　　that is bringing back such pieces, as B states. Furthermore, choices C and E, by using the verb form bring, fail

　　to convey the ongoing nature of the revival properly described by the progressive verb is bringing.

　　Answer to Question 86

　　In E, the best answer, the construction His right hand... crippled clearly and grammatically modifies the subject

　　of the sentence, Horace Pippin. In A, the use of the two participles Having and being is ungrammatical. Choice

　　B is awkward and changes the meaning of the original statement: the point is that Pippin's method of painting

　　arose because of, not in spite of, his injury. Choice C is wordy and awkwardly places the clause beginning that

　　crippled... so that it appears to modify the First World War rather than bullet. In choice D, The should be His,

　　and being should be omitted.

　　172

　　Answer to Question 87

　　Choice A is faulty because it uses the unidiomatic construction depends on if; whether is required to connect

　　depends on with the clause beginning it can.... Choice C uses whether or not where only whether is needed,

　　includes the awkward and wordy construction has the capability to, and unnecessarily repeats the idea of

　　capability with can. Choices D and E use unidiomatic constructions where the phrase its ability to broaden is

　　required. Choice B--idiomatic, concise, and correct--is best.

　　Answer to Question 88

　　The verbs are and calls indicate that the sculpture is being viewed and judged in the present. Thus, neither the

　　past tense verb constituted (in B) nor the present perfect verb have constituted (in C) is correct; both suggest

　　that the statue's features once constituted an artificial face but no longer do so. Also, B would be better if that

　　were inserted after so unrealistic, although the omission of that is not ungrammatical. Choices D and E use

　　unidiomatic constructions with enough: unrealistic enough to constitute would be idiomatic, but the use of

　　enough is imprecise and awkward in this context. Choice A, which uses the clear, concise, and idiomatic

　　construction so unrealistic as to constitute, is best.

　　Answer to Question 89

　　Choices A, B, and C appropriately use the construction "one X for every thirty-two Y's" to describe the ratio of

　　computers to pupils, but only C, the best answer, is error-free. In A, are does not agree with the subject, one

　　microcomputer; furthermore, in A, B, and D, than is used where as is required. Choices D and E reorder and

　　garble the "one X ..." construction, making four times as many refer illogically to pupils.

　　Answer to Question 90

　　The clause beginning Since 1986... indicates that the practice described in the second clause continued for

　　some period of time after it began. Choice D, the best answer, supplies the present perfect have begun, which

　　conveys this continuity; D also uses a construction that is appropriate when "allow" means "permit": allow... to

　　be based on. Choices A, B, and E incorrectly use the past tense began rather than the present perfect;

　　furthermore, in each of these options, they has no referent, since officers is a possessive modifier of fees.

　　Choices A and C include the awkward phrase based on how the funds they manage perform. Choices C and

　　E incorrectly use allow that.. .fees be based.
