English Grammar Quiz: Error Identification and Sentence Completion

Lincoln Park correctly identifies the large public green space that runs along Chicago's North Side lakefront, separating several residential neighborhoods. Grant Park is located in downtown Chicago along the southern lakefront and does not divide northern residential neighborhoods. Millennium Park is a smaller cultural destination within Grant Park and does not serve as a neighborhood divider. This question tests general knowledge of urban geography alongside sentence completion.

"Can be" is correct because it expresses possibility across multiple habitats, which fits the context of migratory birds appearing in different locations depending on conditions. "Is" is singular and does not agree with the plural subject "migratory birds." "Was" is singular past tense, which neither agrees with the plural subject nor fits the general present-tense observation. "Has been" is singular present perfect, which does not agree with the plural subject.

"Benefits" correctly completes the list of what a professional association advances — interests, benefits, and public recognition — as it refers to the collective advantages and protections members receive. "Employment" is too broad and refers to the state of having work rather than a specific advantage the association provides. "Salaries" refers specifically to compensation, which is narrower than the overall scope implied by the sentence. "Contracts" refers to legal agreements rather than a general membership advantage.

"First enacted" correctly introduces a reduced participial phrase indicating when the legislation was passed, functioning as a time modifier for the main clause. "It was first enacted" is a full clause that creates a run-on sentence when combined with the main clause. "Having enacted" implies an active subject performing the enacting, but the act cannot enact itself. "When it enacted" uses active voice incorrectly, as legislation is enacted by legislators, not by itself.

"Were the committee" correctly triggers the inverted subjunctive structure used for hypothetical conditions, equivalent to "If the committee were willing." This inversion is a formal grammatical construction signaling an unlikely or hypothetical scenario. "Should the committee be" is also an inverted conditional but expresses a possibility rather than a contrary-to-fact hypothesis, making it less precise here. "The committee being" is a participial construction that does not form a complete conditional clause. "If the committee is" uses the indicative mood, which does not convey the hypothetical nature of the sentence.

"Most low" is incorrect and should be "lowest." Superlative adjectives in English use either the "-est" suffix or "most" before the base form — never both together. "Low" forms its superlative as "lowest," not "most low." "Hydrogen" correctly functions as the subject of the sentence. "Boiling point" correctly functions as the object noun phrase. "Periodic table" correctly functions as the object of the preposition "on."

"There is" is incorrect and should be "There are." The subject "twenty-eight bones" is plural and requires the plural verb "are." "There is" agrees only with singular subjects. "Twenty-eight bones" correctly functions as the postponed plural subject of the existential construction. "Including those" correctly functions as a participial phrase extending the description. "The wrist" correctly functions as the final element in the list of body parts.

"Extend" is incorrect and should be "extended." The sentence uses a passive construction — "was extended" — which requires the past participle form. The base verb "extend" cannot follow the auxiliary "was" in a passive structure. "Six hours" correctly functions as the object of the preposition "by." "Critical components" correctly functions as the object of the infinitive "to replace." "Backup systems" correctly functions as the object of the infinitive "to test."

This question tests knowledge of correlative conjunctions. "Nor" is correct as written — "neither...nor" is the proper pairing. However, if the original sentence used "or" instead of "nor" (as the source quiz implied), then "or" would be the error since "neither" must pair with "nor," never with "or." "Concludes" correctly functions as the main verb in the present tense. "Awareness" correctly functions as the second element in the "neither...nor" construction. "Structural reform" correctly functions as the object of the preposition "without."

"Is" is incorrect and should be "are." The subject of the sentence is "some of the procedural steps," where "some" refers to a plural noun "steps," requiring the plural verb "are." "Some of" correctly introduces the partitive construction. "Actually redundant" correctly functions as the predicate adjective following the linking verb. "Affecting the outcome" correctly functions as a gerund phrase following the preposition "without."
