Question 10Question

Unlike his classmates who preferred to study in groups, David insisted to prepare for the final exam alone. Which choice is the most appropriate idiomatic phrasing to replace the underlined portion?

Show answer & explanation

Answer: on preparing

Answer

The correct idiomatic choice is 'on preparing' because the verb 'insist' must be paired with the preposition 'on' and a gerund.
The verb 'insisted' idiomatically requires the preposition 'on' followed by a gerund (an -ing verb). Therefore, 'on preparing' is the correct idiomatic phrase.

Step-by-Step Solution

1
Identify the verb that precedes the underlined portion.
The verb is 'insisted'.
The correct preposition and verb form depend on the specific verb being used.
2
Recall the idiomatic preposition and verb form that follow 'insist'.
The verb 'insist' is idiomatically followed by 'on' and a gerund (-ing form).
Using an infinitive like 'to prepare' or prepositions like 'to' or 'for' is grammatically incorrect in this context.
3
Select the option that matches this idiomatic construction.
The option 'on preparing' correctly pairs 'insisted' with 'on' and the gerund 'preparing'.
This forms the standard idiomatic expression 'insisted on preparing'.

Verbs in English often require specific prepositions and verb forms (gerund vs. infinitive) to form correct idiomatic expressions.
Question 11Question

For decades, local planners struggled to preserve the architectural heritage of the old downtown area. Although the city council initially supported the commercial development project, the newly enacted zoning laws prohibit developers to build structures taller than six stories in the historic district.

Which of the following choices is the best replacement for the underlined portion of the sentence?

Show answer & explanation

Answer: prohibit developers from building

Answer

prohibit developers from building
The correct option is 'prohibit developers from building' because the verb 'prohibit' idiomatically pairs with the preposition 'from' and a gerund (an '-ing' verb) to express prevention or restriction. In this sentence, this structure correctly connects the zoning laws' restriction to the action of building tall structures.

Step-by-Step Solution

1
Identify the verb in the underlined portion and analyze the construction that follows it.
The verb is 'prohibit', and it is followed by the object 'developers' and the infinitive phrase 'to build'.
We need to determine if this verb-preposition-verb collocation is idiomatically correct in standard written English.
2
Recall the correct idiomatic preposition and verb form that pair with 'prohibit' when indicating prevention.
The verb 'prohibit' requires the preposition 'from' followed by a gerund (the '-ing' form of a verb).
Phrases like 'prohibit to' or 'prohibit against' violate English idiomatic usage standards.
3
Select the option that correctly implements the 'prohibit [object] from [gerund]' structure.
The option stating 'prohibit developers from building' uses the correct preposition 'from' and the gerund 'building'.
This choice matches standard idiomatic usage and maintains grammatical correctness within the sentence.

Question 12Question

Many literary historians regard the author's diary to be a crucial resource for understanding the social dynamics of the era. Which choice is the best replacement for the underlined portion?

Show answer & explanation

Answer: regard the author's diary as

Answer

regard the author's diary as
The correct option correctly uses the idiomatic construction 'regard [something] as [something else]'. In English, the verb 'regard' is idiomatically paired with 'as' to show how something is perceived, rather than using 'to be' or 'like'.

Step-by-Step Solution

1
Identify the verb and the relationship being established in the sentence.
The verb is 'regard', which is used to express how literary historians perceive the author's diary.
Recognizing the core verb helps determine the appropriate idiomatic preposition or structure that must follow it.
2
Evaluate the idiom required by the verb 'regard'.
The standard English idiom is 'regard [noun] as [noun/adjective]'. Using 'to be', 'like', or 'to being' is unidiomatic.
Applying standard idiomatic conventions allows us to select the correct phrasing.

Question 13Question

Although the talented young software engineer was eager to explore new career opportunities in the fast-paced tech industry, the strict terms of his initial employment contract precluded him to accept any position at a competing firm for at least one year. Consequently, he decided to focus his energy on developing his own independent mobile applications while waiting for the non-compete clause to expire. This strategic decision ultimately allowed him to launch a successful startup of his own.

Which choice is the most appropriate option to replace the underlined portion?

Show answer & explanation

Answer: precluded him from accepting

Answer

precluded him from accepting
The correct choice is 'precluded him from accepting' because the verb 'preclude' idiomatically requires the preposition 'from' followed by a gerund (verb-ing). In the context of the sentence, the non-compete contract prevented the engineer from taking a new job, which is correctly expressed as 'precluded him from accepting' rather than using an infinitive or an incorrect preposition.

Step-by-Step Solution

1
Identify the main verb and its idiomatic requirements in the underlined portion.
The verb is 'precluded'.
Different verbs require specific prepositions and verb forms to be idiomatically correct.
2
Determine the correct preposition and grammatical structure that follows 'preclude'.
The verb 'preclude' must be paired with 'from' followed by a gerund (the -ing form of a verb).
Using an infinitive or incorrect prepositions violates standard English idiomatic usage.
3
Evaluate the options to find the one that matches this required structure.
The option 'precluded him from accepting' matches the correct idiomatic pattern.
This option corrects the preposition and verb form while maintaining standard grammar and context.

Question 15Question

When designing long-term storage protocols, digital archivists must weigh the costs of active maintenance against the risks of data degradation. For many of these professionals, storing raw data on physical magnetic tape drives is preferable than relying solely on cloud-based servers, which remain vulnerable to sudden service interruptions.

Which choice is the most grammatically correct and idiomatic replacement for the underlined portion?

Show answer & explanation

Answer: preferable to

Answer

The correct choice is 'preferable to' because the adjective 'preferable' requires the preposition 'to' to form a standard idiomatic comparison.
The adjective 'preferable' is idiomatically followed by the preposition 'to' when making comparisons. The expression 'preferable to' is the standard grammatical construction used to show that one choice is favored over another.

Step-by-Step Solution

1
Identify the word establishing the comparison in the underlined portion of the sentence.
The sentence uses the adjective 'preferable' to compare storing raw data on physical tape drives with relying on cloud-based servers.
Determining the word that initiates the comparison is necessary to identify which idiomatic preposition must accompany it.
2
Select the preposition that idiomatically completes the phrase containing 'preferable'.
The correct preposition is 'to', making the correct phrase 'preferable to'.
Although colloquial English frequently uses 'than' or 'over', formal standard English requires 'to' when using 'preferable' for comparison.

Question 16Question

To ensure the longevity of the fragile manuscript, the archivist insisted that all researchers adhere to the strict handling guidelines. These rules prevented accidental tears and exposure to moisture.

Which choice best completes the sentence in accordance with standard written English?

Show answer & explanation

Answer: NO CHANGE

Answer

The correct option is 'NO CHANGE' because the verb 'adhere' idiomatically requires the preposition 'to' to express compliance with rules.
The correct choice is the one that retains 'adhere to', as the verb 'adhere' idiomatically requires the preposition 'to' when referring to following rules or guidelines.

Step-by-Step Solution

1
Identify the verb and preposition combination underlined in the sentence.
The underlined phrase is 'adhere to'.
We must verify if 'adhere' is paired with the correct idiomatic preposition in the context of following guidelines.
2
Determine the correct idiomatic preposition that follows the verb 'adhere'.
In standard written English, 'adhere' always pairs with 'to' when referring to sticking to or following a set of rules.
Prepositional idioms are fixed and cannot be substituted with other prepositions even if they seem to convey a similar meaning.
3
Evaluate the alternative options against this idiomatic rule.
The options using 'with', 'by', and 'in' are incorrect because they fail to follow the standard idiomatic construction.
We eliminate options that use incorrect prepositions to connect 'adhere' with 'guidelines'.

Question 17Question

Having spent three consecutive weeks monitoring the volatile ridge, the vulcanologists grew wary of the seismic sensors' frequent false alarms, a complacency that ultimately led them to ignore the evacuation warning.

Which choice is the most appropriate in the context of the sentence?

Show answer & explanation

Answer: weary of

Answer

The option containing 'weary of' is the correct answer because it uses the correct word meaning ('weary' for being tired of something) and pairs it with the correct idiomatic preposition 'of'.
The correct option is 'weary of'. The sentence describes how the vulcanologists grew tired of the constant false alarms, which led to their complacency. The word 'weary' means tired or impatient with something, and it idiomatically pairs with the preposition 'of' when referring to a recurring event or nuisance. Therefore, 'weary of' is both contextually and idiomatically correct.

Step-by-Step Solution

1
Analyze the context of the sentence to determine the intended meaning.
The sentence mentions 'a complacency' and that the vulcanologists 'ignored the evacuation warning.' This indicates they became tired of or desensitized to the false alarms, rather than cautious.
Choosing the correct word requires distinguishing between 'wary' (cautious/alert) and 'weary' (tired/impatient).
2
Select the correct word and determine its idiomatic preposition.
The correct word is 'weary'. When expressing that one is tired of or impatient with a recurring event, the word 'weary' must be followed by the preposition 'of'.
Using 'weary from' implies physical exhaustion resulting from an activity, which does not fit the context of being desensitized to false alarms.

Question 18Question

For decades, the unsigned political pamphlet was attributed for a prominent senator, but recent analysis of the prose style suggests it was actually written by a local activist.

Which choice best fits the underlined portion of the sentence?

Show answer & explanation

Answer: attributed to

Answer

attributed to
The correct answer is 'attributed to' because the verb 'attribute' idiomatically pairs with the preposition 'to' when indicating authorship or source. In this context, the sentence states that the political pamphlet was believed to be written by the senator, making 'attributed to' the only idiomatically correct and logical choice.

Step-by-Step Solution

1
Identify the grammatical and contextual relationship in the sentence.
The sentence discusses a political pamphlet whose authorship was historically credited to a senator, but is now believed to have been written by an activist.
Understanding the context helps determine which preposition correctly links the verb 'attributed' to the noun 'senator'.
2
Recall the correct idiomatic preposition for expressing authorship credit.
The verb 'attribute' requires the preposition 'to' when linking a creation to its creator (e.g., 'attributed to a senator').
Idiomatic word choice requires using standard prepositional collocations recognized in formal English.
3
Evaluate the distractors against the context.
'Attributed for' and 'attributed with' are unidiomatic, while 'attributed by' suggests the senator performed the action of attributing, which is illogical here.
Eliminating grammatically or contextually incorrect prepositions ensures the most precise and idiomatic choice is selected.

Question 19Question

The sudden deterioration of the sixteenth-century painting was attributed to the high humidity levels in the gallery, which accelerated the breakdown of its organic pigments.

Which of the following choices best completes the underlined portion of the sentence?

Show answer & explanation

Answer: NO CHANGE

Answer

NO CHANGE
The correct idiomatic expression is 'attributed to' when explaining that something is the cause of a particular result. The option 'NO CHANGE' correctly uses this preposition to show that the high humidity caused the painting to deteriorate.

Step-by-Step Solution

1
Identify the relationship between the deterioration of the painting and the high humidity levels.
The high humidity levels are identified as the cause of the deterioration.
This establishes that the sentence requires an idiomatic construction linking an effect to its cause.
2
Evaluate the idiom required for the verb 'attributed' in this context.
The correct preposition to pair with 'attributed' when linking an effect to its cause is 'to'.
English idiom rules require the pattern 'attribute [something] to [a cause]' or '[something] is attributed to [a cause]'.
3
Compare the options against the correct idiomatic form.
The option 'NO CHANGE' preserves 'attributed to', whereas the other options use incorrect prepositions ('from', 'by', 'with').
Selecting the correct preposition ensures the sentence is idiomatically and grammatically correct.

Question 20Question

Because fresco paintings are applied directly to wet plaster, they are especially susceptible of damage from moisture fluctuations in the surrounding gallery. Conservators must therefore monitor relative humidity levels with extreme precision.

Which choice is correct?

Show answer & explanation

Answer: susceptible to

Answer

susceptible to
The correct answer is 'susceptible to' because the adjective 'susceptible' requires the preposition 'to' to form a grammatically correct idiomatic construction in English when designating a source of vulnerability.

Step-by-Step Solution

1
Identify the adjective in the underlined portion and analyze its relationship to the noun 'damage'.
The adjective is 'susceptible', expressing vulnerability or open exposure to harm.
This helps determine the correct preposition needed to connect the adjective to its object.
2
Evaluate the idiomatic preposition required by standard English conventions following 'susceptible'.
The standard English idiom is 'susceptible to' followed by the source of vulnerability.
Other preposition options such as 'of', 'for', and 'with' do not form standard idiomatic collocations with 'susceptible' in this context.
