Correct Answer: C

Rationale: In this sentence, 'It's' is the contraction for 'it is,' and 'than' is used correctly for comparisons (e.g., better than).
Therefore, sentence C is correct because it uses 'It's' (it is) and 'than' (for comparison) properly.

Choices A, B, and D are incorrect.
Choice A lacks the necessary apostrophe in 'It's' (it is) and incorrectly uses 'then' instead of 'than.'
Choice B incorrectly uses 'Its' (possessive form) instead of 'It's.'
Choice D lacks the necessary apostrophe in 'It's' (it is) and incorrectly uses 'then' instead of 'than.'

Correct Answer: C

Rationale: The correct answer is C. A citation is required when directly quoting another author's opinion to give credit and avoid plagiarism.

Choices A, B, and D do not necessitate citations as they involve the author's own opinion, personal experience, and description of a play, respectively, without directly quoting another source.

Correct Answer: B

Rationale: The correct answer is B. In this context, 'peaked' should be 'peeked,' meaning to take a quick look. The other choices are incorrect: A is wrong because 'sheer' is the correct term referring to the absolute or complete number of people; C is incorrect as 'through' is the right term indicating looking by going across something; D is inaccurate as 'scene' is the correct term for a part of a play or film.

Correct Answer: C

Rationale: A compound sentence is made up of two independent clauses connected by a coordinating conjunction (such as 'and,' 'but,' 'so,' etc.) or a semicolon. In this case, 'The baby was sick' and 'I decided to stay home from work' are two independent clauses connected by the coordinating conjunction 'so.'
Choice A is a simple sentence with one independent clause.
Choice B is a complex sentence with an independent clause 'Marissa last saw Elena' and a dependent clause 'and talked to her this morning.'
Choice D is also a simple sentence with one independent clause.

Correct Answer: C

Rationale: The correct answer is C: 'All-powerful'. 'Omnipotent' means having unlimited power or authority.
Choice A, 'Well-worn', does not relate to the definition of omnipotent.
Choice B, 'Overreaching', implies extending beyond proper limits but does not capture the essence of unlimited power.
Choice D, 'Angry', does not align with the meaning of omnipotent.
