Explanation

In passive voice, the object of the active sentence becomes the subject of the passive sentence.

The correct structure of the passive voice with the modal verb "might" in the perfect aspect is:

[Subject] + might have been + past participle + [by + agent].

So, "The insurance money might have been paid in instalments by him" is correctly structured

Explanation

 The phrase "reckon on" means to rely or depend on something or someone.

"Reckon with," "reckon at," and "reckon to" are not used in this context.

Making "on" the correct choice.

Explanation

A passive sentence emphasizes the object of the action (the persons).

In the original sentence, "The road accident" is the subject, actively performing the action of killing.

To make it passive, the object ("seven persons") becomes the subject, and the verb is changed to a form of "be" with the past participle ("killed").

Option (A) correctly reflects this structure. 

Explanation

 Parentheses resemble two curved vertical lines: ( ).

A single one of these punctuation marks is called a parenthesis.

Explanation

Explanation

The correct sentence is:

A) The intricate interplay of genetics and epigenetics, along with the influence of environmental factors, shape an individual's health outcomes.

Here's why:

• Subject-Verb Agreement: The plural subject "intricate interplay" requires the plural verb "shape."
• Noun Pluralization: "Genetics" and "epigenetics" are already plural nouns.

The other options have either incorrect pluralization or subject-verb agreement errors.

Explanation

The correct sentence is:

A) Regardless of the myriad challenges, the dedicated team is determined to pursue their ambitious goals.

Here's why:

• Subject-Verb Agreement: The subject "team" is singular, so the verb "is" is used correctly.
• "Myriad" is already a singular adjective, so adding "s" to it would be incorrect.

Therefore, option A is the grammatically correct choice.

Explanation

The correct sentence is:

A) The enigmatic nature of dark matter continues to baffle cosmologists, as its properties remain elusive.

Here's a breakdown of why this is correct:

• Subject-Verb Agreement: "Nature" is singular, so the verb "continues" is singular.
• Pronoun-Antecedent Agreement: "Its" refers to "nature," which is singular.

The other options have either subject-verb agreement errors or incorrect pronoun usage.

Explanation

The grammatically correct sentence is:

(A) Despite her exhaustion, the dedicated scientist continued to meticulously analyze the intricate data sets.

• "Despite her exhaustion" correctly shows the contrast between her fatigue and her dedication.
• "The dedicated scientist" uses the singular "scientist" since the sentence focuses on one individual.
• "Intricate data sets" is the correct form, as "data" is typically treated as plural, and "sets" refers to multiple collections of data.
• "Meticulously analyze" is the correct verb form to match the context of detailed examination.

Explanation

The correct sentence is:

A) Irrespective of the diverse opinions, the committee has convened to discuss the pressing issues.

Here's a breakdown of why this is correct:

• "Irrespective of" is a prepositional phrase that correctly modifies the entire clause.
• "The committee" is a singular subject, so the verb should be singular as well: "has convened."

The other options have either grammatical errors or incorrect usage of the prepositional phrase.
