A.I. Explanation:

Correct answer: argued

Explanation: The verb 'argued' fits grammatically as it is in the past tense, aligning with the past context of the study. It also conveys the action of presenting a case or reasoning, which is appropriate in an academic context.

Meaning: 'Argued' means to present reasons for or against something, indicating that the authors made a case regarding the happiness of bronze medallists.

Wrong options:

• exchanged: 'Exchanged' implies a trade or swap, which does not fit the context of presenting an argument or reasoning.
• talked: 'Talked' is too informal and vague for an academic context, lacking the specificity of presenting a reasoned argument.
• exempted: 'Exempted' means to free from an obligation, which is unrelated to the context of discussing findings from a study.

Correct answer: whereas

Explanation: The conjunction 'whereas' effectively contrasts the two groups being discussed, indicating a difference in comparison behavior between bronze and silver medallists, fitting grammatically and contextually.

Meaning: 'Whereas' is used to show a contrast between two statements, highlighting the differing comparisons made by the two groups.

Wrong options:

• there: 'There' is an adverb indicating a place, which does not provide the necessary contrast between the two subjects.
• therefore: 'Therefore' indicates a conclusion or result, which does not fit the context of contrasting the two groups' behaviors.
• moreover: 'Moreover' adds information but does not establish the necessary contrast between the two comparisons.

Correct answer: salient

Explanation: The adjective 'salient' is appropriate as it describes something that is prominent or important, fitting the context of the counterfactuals being discussed. It aligns grammatically as it modifies 'counterfactuals' correctly.

Meaning: 'Salient' means something that stands out or is particularly noticeable, indicating the importance of the counterfactuals in the study.

Wrong options:

• used: 'Used' is too vague and does not convey the significance or prominence of the counterfactuals in the context.
• great: 'Great' is subjective and does not specifically relate to the prominence or importance of the counterfactuals.
• superb: 'Superb' implies excellence but lacks the specific connotation of prominence that 'salient' provides.

Correct answer: actually

Explanation: The adverb 'actually' fits grammatically and contextually as it emphasizes the reality of what occurred, contrasting with the counterfactuals being discussed.

Meaning: 'Actually' means in fact or really, reinforcing the distinction between perceived and actual outcomes.

Wrong options:

• securely: 'Securely' implies safety or stability, which does not relate to the context of discussing actual events.
• notionally: 'Notionally' refers to something in theory rather than in reality, which contradicts the intended meaning of emphasizing actual occurrences.
• really: 'Really' is informal and less precise than 'actually' in an academic context, lacking the same emphasis on factuality.

Correct answer: prior

Explanation: The adjective 'prior' fits grammatically as it describes expectations that come before an event, aligning with the context of expectations held by athletes.

Meaning: 'Prior' means existing or coming before something else, indicating the expectations that athletes have before competing.

Wrong options:

• first: 'First' implies a sequence rather than the concept of expectations that precede an event, which does not fit the context.
• last: 'Last' suggests the final position, which contradicts the idea of expectations that come before an event.
• guessed: 'Guessed' implies uncertainty and does not convey the established nature of expectations in this context.

Correct answer: those

Explanation: The pronoun 'those' fits grammatically as it refers back to the expectations of bronze medallists, maintaining consistency in number and clarity in reference.

Meaning: 'Those' refers to the expectations of bronze medallists, distinguishing them from the expectations of silver medallists.

Wrong options:

• there: 'There' is an adverb indicating a place, which does not refer back to the expectations and lacks grammatical coherence in this context.
• which: 'Which' is a relative pronoun that does not appropriately refer to the expectations in this context, lacking clarity.
• what: 'What' is interrogative and does not fit the context of referring to specific expectations, making it grammatically incorrect.
