Correct Answer: D

Rationale: The correct answer is 'D: Justification.' Justification means showing that an action is reasonable or right. In this context, it implies that there was no valid reason or excuse for the way she treated her boyfriend.

Choices A, B, and C are incorrect. An 'alibi' is an excuse to explain one's whereabouts during a crime, not applicable here. 'Rational' means based on reason or logic, which does not fit the context of the sentence. 'Reasonable' means fair and sensible, but the sentence suggests a lack of valid explanation rather than fairness or sensibility.

Correct Answer: D

Rationale: The correct answer is 'D: Discharge.' 'Flux' is a term used to describe the flow or discharge of fluid.
Therefore, 'Discharge' is the most appropriate synonym in this context. The other choices are incorrect:
A) 'Quantity' refers to an amount,
B) 'Inflation' refers to the rise in prices, and
C) 'Strength' refers to the power or quality of being strong.

Correct Answer: C

Rationale: The correct answer is 'C: Immigrant.' An immigrant is a person who comes to live permanently in a foreign country, such as the United States.
Choice A, 'Immigrate,' refers to the action of entering a foreign country to live there.
Choice B, 'Migrate,' means to move from one place to another.
Choice D, 'Emigrant,' is someone who leaves their own country to settle permanently in another.

Correct Answer: C

Rationale: The term 'flexible' accurately describes the type of tube used in the given context. A 'solid' tube would not have been suitable for navigating a curved pipe as it is not pliable. 'Rigid' implies stiffness and inflexibility, making it unsuitable for the task. 'Perforated' means pierced with holes, which is unrelated to the plumber's task of opening up a curved pipe.

Correct Answer: A

Rationale: The correct answer is 'A: Giant catnip patch in the sky.' This phrase is a euphemism for death, as it softens the reality of Thomas the Cat's passing.
Choice B, 'The cutest kitten around,' is a compliment and not a euphemism.
Choice C, 'He'll be missed by everyone,' is a straightforward statement without a euphemistic element.
Choice D, '
Today we gather to remember,' is a typical opening statement for a memorial gathering and is not a euphemism.
