Correct Answer: B

Rationale: The correct answer is B: 'Sudden.' Abrupt means something that occurs suddenly, without warning or preparation. It is the opposite of gradual, delayed, or relaxed, which imply a slower or more gentle pace of change or action.

Correct Answer: B

Rationale: The correct answer is 'B: The team of players is winning.' The error in this sentence is a subject-verb agreement issue. 'Team' is a singular noun, so it should take a singular verb 'is' instead of 'are.' The subject-verb agreement rule states that singular subjects should be paired with singular verbs, while plural subjects should be paired with plural verbs. Choices A, C, and D all demonstrate correct subject-verb agreement as they correctly match singular subjects ('group,' 'list,' 'pile') with singular verbs ('is,' 'is,' 'is').

Correct Answer: C

Rationale: Another word for UNDER OBSERVATION is surveillance. Surveillance refers to the close observation of a person, group, or place, especially in a secret or discreet manner. It involves monitoring and watching over someone or something closely for a specific purpose. Therefore, the word 'surveillance' is the most suitable synonym for under observation in this context. Choice A, 'Cognition,' refers to the mental process of acquiring knowledge and understanding through thoughts, experience, and the senses; it is not synonymous with under observation. Choice B, 'Isolation,' means the process or fact of isolating or being isolated, which does not convey the idea of close monitoring. Choice D, 'Assessment,' involves evaluating or judging the nature, ability, or quality of something, which is different from the act of observing closely.

Correct Answer: B

Rationale: Lethargic refers to a state of sluggishness or drowsiness, making it difficult for a person to become alert or aroused. This term is the opposite of being active, energized, or wide awake. Choice A is incorrect as 'lethargic' is the opposite of 'active.' Choice C is incorrect as 'lethargic' implies a lack of energy. Choice D is incorrect as 'lethargic' signifies drowsiness, the opposite of being 'wide awake.' The correct answer is B.

Correct Answer: A

Rationale: The correct answer is A: 'Predict.' Anticipate means to expect or foresee something happening in the future. 'Predict' is a synonym for anticipate as both involve forecasting or making an inference about a future event. 'Evaluate' means to assess or judge something, 'Compare' means to note similarities and differences, and 'Forestall' means to prevent or hinder something. These words do not have the same meaning as 'Anticipate.'
