Correct Answer: A

Rationale: The correct answer is A: Chronology. Chronology is the science of arranging events in their order of occurrence in time. It helps to create a timeline and understand historical or sequential events. Helicon, Natation, and Documentation do not pertain to the chronological order of events, making them incorrect choices in this context.

Correct Answer: C

Rationale: The correct answer is 'Interview.' In the context of receiving test results, an interview is a scenario where the student could interact with an authority figure to discuss and receive personal feedback on their performance. The other options, such as 'Evacuation,' 'Sleep,' and 'Laboratory,' do not align with the typical setting where one would be informed about test results. Therefore, 'Interview' is the most appropriate word that fits the context of the sentence.

Correct Answer: C

Rationale: The correct answer is 'C: Practical.' Feasible means capable of being done, accomplished, or put into practice, making 'Practical' the most appropriate synonym in this context. 'Unlikely,' 'Awesome,' and 'Impossible' do not convey the same meaning as feasible. Therefore, when something is feasible, it is within the realm of practicality or possibility, rather than being unlikely, awesome, or impossible. Understanding the meaning of 'feasible' is essential for effective communication and decision-making, as it helps individuals assess the practicality and achievability of various tasks or projects.

Correct Answer: A

Rationale: The correct answer is 'Credulous.' Credulous means being too ready to believe things, especially when it is unlikely that they are true. In this scenario, the individual who unquestioningly believes a friend's story about seeing a UFO is described as credulous because they accept the story without questioning its validity. Being credulous implies a tendency to believe things without much evidence or critical thinking, which fits the situation described in the question.

Correct Answer: D

Rationale: The term 'efface' means 'to rub out or erase.' When something is effaced, it is being removed or erased, implying a process of elimination. This word is commonly used to describe the act of wiping out or erasing something, making choice D the correct definition in this context.
