Could anyone explain this question?
Hi,
The given question is based on the concept of Subject-Verb Agreement (SVA).
The usual pattern of a sentence is Subject – Verb – Object. However, we sometimes find sentences that put the verb first and the Subject later. This is one such sentence.
In questions that are partially underlined, doing a quick scan of the first and last words of the option can be helpful. If the first or last word of the option is a verb, one point of elimination is likely to be either SVA or tense or both.
In this sentence, the last word is the verb ‘was’, ‘were’ or ‘are.
So, let us start by choosing between ‘was’ and ‘were’, which are the singular and plural forms of the ‘be’ verb.
To decide whether the sentence requires ‘was’ or ‘were’, we need to identify the subject, which in this case, appears after the verb. The subject in this sentence is – “the invention of the reflecting telescope the basic design behind all large telescopes used today, the creation and explanation of his three laws of motion, and the development of the law of universal gravitation”.
Please note the use of the conjunction ‘and’. The rules of SVA state that if two or more nouns or pronouns are joined by the conjunction ‘and’, the subject is considered plural and the verb must also be plural.
In this sentence, we have three noun phrases joined by ‘and’.
• the invention of the reflecting telescope the basic design behind all large telescopes used today
• the creation and explanation of his three laws of motion
• the development of the law of universal gravitation”.
So, the correct verb is ‘were’ and not ‘was.
This helps us eliminate Options A and C. To decide between ‘were’ and ‘are, two verbs in the past and present tense, we need a clue from the remaining part of the sentence. However, in this sentence, we don’t have a clear clue.
So, let us look for another reason to eliminate another two options.
Two options begin with the preposition ‘of’ and one with the preposition ‘among’. The sentence mentions three achievements in particular that are part of all his achievements. The preposition ‘among’ is used to convey the meaning ‘part of’. The preposition ‘of’ conveys possession or belonging.
Therefore, we can eliminate Options D and E. Option B is the most appropriate answer.I hope this helps.
