MAT Exam 2021 Paper

Concept:This is a paragraph-arrangement question. The correct sequence is found by identifying the introductory sentence and then linking pronouns, connectors, and related ideas.Explanation:Sentence B opens the paragraph best because it introduces the idea that nature provides the body with “regulators and protectors.”D follows B naturally because the phrase “these controllers” refers back to the regulators and protectors stated in B.C then identifies those controllers as our endocrine glands.A continues the idea by commenting on the endocrine glands — the knowledge available about them is very limited.Finally, E closes the passage with the word “However,” contrasting with A by giving an accepted scientific fact about these glands: they secrete hormones directly into the blood.Thus, the logical and coherent order of the sentences is B, D, C, A, E.Answer:BDCAE, i.e., option D.
