English grammar - May 11, 05:09

Solution

Correct: A

In sentences using 'neither...nor', the verb must agree with the subject closest to it. In this case, 'teacher' is singular, so the verb 'is' (singular) is correct.

Solution

Correct: B

'Everyone' is an indefinite pronoun and is singular. Therefore, it requires a singular pronoun for agreement. 'His or her' is the most appropriate gender-neutral singular option in formal writing. While 'his' could be used in some contexts, 'his or her' is more inclusive and precise for 'everyone'.

Solution

Correct: B

The main clause uses the past perfect tense ('had thoroughly researched') to indicate an action completed before another past action. Therefore, the subordinate clause requires the simple past tense ('arrived') to show the subsequent past event.

Solution

Correct: C

Parallel structure requires that items in a series have the same grammatical form. In option C, 'efficient' (adjective), 'organized' (adjective), and 'a great communicator' (noun phrase acting as an adjective/description) are all parallel in their descriptive function. Options A, B, and D break this parallelism with different grammatical constructions.

Solution

Correct: B

A comma splice occurs when two independent clauses are joined only by a comma (as in A). Option B correctly uses a semicolon to separate two closely related independent clauses. Option C is incorrect because 'therefore' is a conjunctive adverb and requires a semicolon before it and a comma after it when joining independent clauses. Option D misuses a colon.

Solution

Correct: B

In the original sentence, 'walking to class' seems to modify 'dog' instead of 'student'. 'With a wagging tail' describes the dog. Option B correctly places 'Walking to class' to modify 'the student', making the meaning clear that the student was walking, and the dog they saw had a wagging tail.

Solution

Correct: C

A comma is required after an introductory phrase or clause that precedes the main clause. 'After a long and tiring journey' is an introductory phrase, so a comma should follow it.

Solution

Correct: C

The possessive form of 'it' is 'its' (without an apostrophe). 'It's' is a contraction of 'it is' or 'it has'. Options A, B, and D misuse the apostrophe for possession.

Solution

Correct: C

In the active voice, the subject of the sentence performs the action. In option C, 'The chef' (subject) performs the action 'prepared'. In the other options, the subject receives the action (e.g., 'The ball was thrown').

Solution

Correct: B

This is a Type 2 conditional sentence, used for hypothetical or unlikely situations. The structure is 'If + simple past (subjunctive 'were' for 'be' verb)', 'would + base form of verb'. Therefore, 'If I were a millionaire, I would travel around the world' is correct.

Solution

Correct: A

When comparing two items or persons, the comparative form of the adjective is used. 'Better' is the comparative form of 'good'. 'Best' is the superlative form, used for three or more.

Solution

Correct: D

The correct idiom for expressing preference between two things is 'prefer X to Y'. So, 'I prefer to read books to digital screens' is grammatically correct.

Solution

Correct: A

The indefinite article 'a' is used before words that begin with a consonant sound ('new'). The indefinite article 'an' is used before words that begin with a vowel sound ('antique').

Solution

Correct: B

'Effect' (noun) means a result or consequence, which fits the first blank ('The result of the new policy'). 'Affect' (verb) means to influence or have an impact on, which fits the second blank ('will influence everyone').

Solution

Correct: B

'Because' is a subordinating conjunction that correctly introduces a cause-effect relationship. The rain (cause) led to the decision to postpone (effect). 'Although' implies contrast, 'However' is a conjunctive adverb, and 'Despite' requires a noun phrase or gerund.

Solution

Correct: B

Option B uses the subordinating conjunction 'when' to effectively combine the two ideas, indicating that the car broke down *while* they were driving on the highway. This creates a complex sentence with a main clause and a subordinate clause indicating time. Option A creates a compound sentence, option C uses a semicolon correctly but doesn't show the temporal relationship as clearly as B, and option D creates a dangling modifier, suggesting the car was driving.

Solution

Correct: A

'Incredibly' is an adverb that modifies the adjective 'fast'. 'Fast' describes 'runner'. 'Easily' is an adverb modifying the verb 'won'.

Solution

Correct: A

A sentence fragment is an incomplete sentence, often lacking a subject or a finite verb. Option A is a participial phrase that lacks a subject performing the action and a finite verb to make it a complete thought. Options B, C, and D are all complete sentences.

Solution

Correct: A

When items in a list themselves contain commas (e.g., 'Paris, France'), semicolons are used to separate the larger items to avoid confusion. Option A correctly uses semicolons to separate the city-country pairs.

Solution

Correct: B

In this context, a noun meaning 'failure' or 'collapse' is required. 'Breakdown' is the correct single-word noun. 'Break down' (two words) is a phrasal verb. 'Break-down' (hyphenated) is an older or less common variant of the noun.
