All questions of RSMSSB JE Civil Mock Test Series 2026 for Civil Engineering (CE) Exam

The sentence states that the functional aspects of biodiversity are broad and vague, and as a result, they need further action to become more scientifically valuable. We are asked to select two answer choices that would complete the sentence and maintain the same meaning.

Explanation:
Let's evaluate each option and see if it fits the sentence:

A) Stratagem: A stratagem refers to a plan or scheme. In the context of the sentence, it does not make sense to say that the functional aspects of biodiversity require a plan or scheme to become more scientifically valuable. Therefore, option A is not suitable.

B) Validation: Validation means the act of confirming or proving the accuracy or truth of something. In the context of the sentence, it makes sense to say that the functional aspects of biodiversity require further validation to become more scientifically valuable. This option fits the meaning of the sentence.

C) Negation: Negation refers to the act of denying or negating something. In the context of the sentence, it does not make sense to say that the functional aspects of biodiversity require negation to become more scientifically valuable. Therefore, option C is not suitable.

D) Substantiation: Substantiation refers to the act of providing evidence or support for something. In the context of the sentence, it makes sense to say that the functional aspects of biodiversity require further substantiation to become more scientifically valuable. This option fits the meaning of the sentence.

E) Abrogation: Abrogation refers to the act of repealing or abolishing something. In the context of the sentence, it does not make sense to say that the functional aspects of biodiversity require abrogation to become more scientifically valuable. Therefore, option E is not suitable.

Conclusion:
From the evaluation above, options B (validation) and D (substantiation) are the two choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.
