Correct Answer: B

Rationale: The correct answer is 'I'. In this sentence, 'I' is the subject pronoun that should be used to complete the sentence correctly. 'Me' is an object pronoun, 'myself' is a reflexive pronoun, and 'mine' is a possessive pronoun, none of which are suitable in this context.

Correct Answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

Correct Answer: B

Rationale: The correct answer is B: 'Ordinary.' Banal refers to something that is common, unoriginal, or lacking in originality. Choices A, C, and D are incorrect because banal does not mean interesting, boring, or creative; it specifically conveys the idea of being mundane or lacking in freshness.

Correct Answer: B

Rationale: The correct answer is 'B: Hindering.' Inhibiting means to hinder or slow down a process.

Choice C, 'Energizing,' is the opposite of inhibiting, as it means to provide energy or stimulate rather than hinder.

Correct Answer: B

Rationale: The correct answer is B: 'To expel feces.' Defecate refers to the act of eliminating solid waste from the body.
