Some buildings that were destroyed and heavily damaged in the earthquake last year were constructed in violation of the city's building code.
(A) Some buildings that were destroyed and heavily damaged in the earthquake last year were
(B) Some buildings that were destroyed or heavily damaged in the earthquake last year had been
(C) Some buildings that the earthquake destroyed and heavily damaged last year have been
(D) Last year the earthquake destroyed or heavily damaged some buildings that have been
(E) Last year some of the buildings that were destroyed or heavily damaged in the earthquake had been
答案：B
解析：Choice B is best. Choices A and C illogically state that some buildings were both destroyed and damaged; or is needed to indicate that each of the buildings suffered either one fate or the other. In using only one verb tense, were, A fails to indicate that the buildings were constructed before the earthquake occurred. Choices C and D use the present perfect tense incorrectly, saying in effect that the buildings have been constructed after they were destroyed last year. Choice E suggests that the construction of the buildings, rather than the earthquake, occurred last year, thus making the sequence of events unclear. Only B uses verb tenses correctly to indicate that construction of the buildings was completed prior to the earthquake.

From the earliest days of the tribe, kinship determined the way in which the Ojibwa society organized its labor, provided access to its resources, and defined rights and obligations involved in the distribution and consumption of those resources.
(A) and defined rights and obligations involved in the distribution and consumption of those resources
(B) defining rights and obligations involved in their distribution and consumption
(C) and defined rights and obligations as they were involved in its distribution and consumption
(D) whose rights and obligations were defined in their distribution and consumption
(E) the distribution and consumption of them defined by rights and obligations
答案：A
解析：Choice A is best. The activities listed are presented as parallel ideas and should thus be expressed in grammatically parallel structures. Choice A correctly uses the simple past tense defined to parallel organized and provided. Choice A also correctly joins the last two parallel phrases with and clearly expresses the relationship of rights and obligations to resources. Choice C preserves parallelism but is wordy, and its has no logical referent. Choices B, D, and E each replace the verb phrase with a subordinate modifier, violating parallelism and making the statements ungrammatical. Furthermore, it is unclear what defining ... consumption in B is intended to modify; in D, whose incorrectly attributes rights and obligations to resources', and E presents rights and obligations as defining, rather than as being defined.

A report by the American Academy for the Advancement of Science has concluded that much of the currently uncontrolled dioxins to which North Americans are exposed comes from the incineration of wastes.
(A) much of the currently uncontrolled dioxins to which North Americans are exposed comes
(B) much of the currently uncontrolled dioxins that North Americans are exposed to come
(C) much of the dioxins that are currently uncontrolled and that North Americans are exposed to comes
(D) many of the dioxins that are currently uncontrolled and North Americans are exposed to come
(E) many of the currently uncontrolled dioxins to which North Americans are exposed come
答案：E
解析：Choices A, B, and C are flawed because the countable noun dioxins should be modified by many rather than much, which is used with uncountable nouns such as "work" and "happiness." In addition, both A and C incorrectly use the singular verb comes with the plural noun dioxins. Choices C and D are needlessly wordy, and D requires that before North Americans, to be grammatically complete. Choice E, the best answer, is both grammatically correct and concise.

In June of 1987, The Bridge of Trinquetaille, Vincent van Gogh's view of an iron bridge over the Rhone sold for $20.2 million and it was the second highest price ever paid for a painting at auction.
(A) Rhone sold for $20.2 million and it was
(B) Rhone, which sold for $20.2 million, was
(C) Rhone, was sold for $20.2 million,
(D) Rhone was sold for $20.2 million, being
(E) Rhone, sold for $20.2 million, and was
答案：C
解析：A comma is needed after Rhone in choices A and D to set off the modifying phrase that begins Vincent...; without the comma, the phrase appears to be part of the main clause, and it is thus unclear what noun should govern the verb sold. Furthermore, it in A has no logical referent, and being in D is not idiomatic. Choices B and E produce the illogical statement that the painting was the second highest price. Choice C, the best answer, avoids this problem by using a noun phrase in which price clearly refers to $20.2 million. And by using a comma after Rhone to set off the phrase that modifies The Bridge of Trinquetaille, C makes the painting the subject of was sold.

Bufo marinus toads, fierce predators that will eat frogs, lizards, and even small birds, are native to South America but were introduced into Florida during the 1930's in an attempt to control pests in the state's vast sugarcane fields.
(A) are native to South America but were introduced into Florida during the 1930's in an attempt to control
(B) are native in South America but were introduced into Florida during the 1930's as attempts to control
(C) are natives of South America but were introduced into Florida during the 1930's in an attempt at controlling
(D) had been native to South America but were introduced to Florida during the 1930's as an attempt at controlling
(E) had been natives of South America but were introduced to Florida during the 1930's as attempts at controlling
答案：A
解析：Choice A is best. The phrasing are native to correctly suggests that the toad species is indigenous to, and still exists in, South America. In B, native in is unidiomatic; in C and E, natives of illogically suggests that each toad now in Florida hails from South America. In D and E, had been inaccurately implies that the toads are no longer native, or indigenous, to South America, and introduced to Florida is unidiomatic. Both as attempts in B and E and as an attempt in D are wrong because the attempt consists not of the toads themselves, but of their introduction into the environment. The correct phrase, in an attempt, should be completed by an infinitive (here, to control), as in A.

While some academicians believe that business ethics should be integrated into every business course, others say that students will take ethics seriously only if it would be taught as a separately required course.
(A) only if it would be taught as a separately required course
(B) only if it is taught as a separate, required course
(C) if it is taught only as a course required separately
(D) if it was taught only as a separate and required course
(E) if it would only be taught as a required course, separately
答案：B
解析：Choice B is best: in sentences expressing a conditional result (x will happen ify happens), the verb of the main clause should be in the future tense and the verb of the if clause should be in the present indicative. Thus, is taught (in B) is consistent with will take, whereas would be taught (in A and E) and was taught (in D) are not. For clarity, only in C, D, and E should immediately precede the entire;/clause that it is meant to modify. Also, the intended meaning is distorted when the adverb separately is used to modify required, as in A and C, or taught, as in E; B correctly uses the adjective separate to modify course.

Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.
(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there
答案：D
解析：All of the choices but D contain ambiguities. In A and B the words which and where appear to refer to sediments, and in E it is not clear what consistent describes. In A, C, and E, there is no logical place to which there or its could refer. In D, the best choice, the phrase sediments from the Baltic Sea tells where the sediments originate, findings provides a noun for consistent to modify, and in the area clearly identifies where the industrial activity is growing.

For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, a method to protect warriors against enemy arrows and spears.
(A) a method to protect
(B) as a method protecting
(C) protecting
(D) as a protection of
(E) to protect
答案：C
解析：Choice C is best because the participle protecting begins a phrase that explains what the shields did. Choices A and B awkwardly use the singular word method to refer to items of military equipment rather than to the use of such items. Also, a method of protecting would be more idiomatic than a method to protect in A or a method protecting in B. In B and D, as is incorrect; also, a protection in D has no noun for which it can logically substitute. Choice E is incomplete; used to protect would have been acceptable.

In metalwork one advantage of adhesive-bonding over spot-welding is that the contact, and hence the bonding, is effected continuously over a broad surface instead of a series of regularly spaced points with no bonding in between.
(A) instead of
(B) as opposed to
(C) in contrast with
(D) rather than at
(E) as against being a
答案：D
解析：The corrected sentence must contrast an effect of spot-welding with an effect of adhesive-bonding. To do so logically and grammatically, it must describe the effects in parallel terms. When inserted into the sentence, D produces the parallel construction over a broad surface rather than at a series. Having no word such as over or at indicate location, choices A, B, and C fail to complete the parallel and so illogically draw a contrast between surface and series. In E, as against being is a wordy and unidiomatic way to establish the intended contrast. Choice D is best.

Defense attorneys have occasionally argued that their clients' misconduct stemmed from a reaction to something ingested, but in attributing criminal or delinquent behavior to some food allergy, the perpetrators are in effect told that they are not responsible for their actions.
(A) in attributing criminal or delinquent behavior to some food allergy
(B) if criminal or delinquent behavior is attributed to an allergy to some food
(C) in attributing behavior that is criminal or delinquent to an allergy to some food
(D) if some food allergy is attributed as the cause of criminal or delinquent behavior
(E) in attributing a food allergy as the cause of criminal or delinquent behavior
答案：B
解析：In choices A, C, and E, in attributing ... behavior modifies the perpetrators, producing the illogical statement that the perpetrators rather than the defense attorneys are attributing behavior to food allergies. Choice C is also wordy, and attributing ... as is unidiomatic in E. In the correct form of the expression, one attributes x, an effect, to y, a cause; or, if a passive construction is used, x is attributed to y. D avoids the initial modification error by using a passive construction (in which the attributors are not identified), but attributed x as the cause of y is unidiomatic. Choice B is best.
