Meaning: 'Appear' means to seem or give the impression of being something, which in this context refers to how altruistic actions might be perceived.

Wrong options:

• be: The verb 'be' is too vague and does not convey the sense of perception required in this context; it simply indicates existence without implying appearance.
• claim: 'Claim' suggests asserting something as a fact, which does not fit the context of discussing how actions are perceived by others.
• occur: 'Occur' implies happening or taking place, which does not align with the idea of how actions are perceived or seem to others.

Correct answer: caused

Explanation: The word 'caused' is the correct choice as it indicates a direct influence or reason behind the action of rushing into the burning house. It is in the past tense, which is consistent with the narrative of the sentence, and it logically connects the instinct to the action taken.

Meaning: 'Caused' means to bring about or make something happen, indicating that there was a reason behind the action taken to save the neighbor.

Wrong options:

• made: While 'made' could imply creation or causation, it is less specific than 'caused' and does not convey the same direct influence on the action.
• took: 'Took' suggests an action was performed but does not imply causation or reason, making it less suitable in this context.
• provoked: 'Provoked' implies a reaction to something, which does not fit the context of discussing the instinct that led to the action.

Correct answer: risk

Explanation: The word 'risk' is appropriate as it denotes exposure to danger, which aligns with the context of putting one's life in jeopardy. It fits grammatically as a noun that complements the verb 'put' and maintains the overall meaning of the sentence.

Meaning: 'Risk' refers to the possibility of loss or injury, indicating the danger involved in the action of saving the neighbor.

Wrong options:

• danger: While 'danger' is related, it does not fit grammatically as it would require a different structure (e.g., 'put your life in danger').
• trouble: 'Trouble' implies difficulty but lacks the specific connotation of danger that 'risk' provides, making it less precise in this context.
• peril: 'Peril' is synonymous with danger but is less commonly used in everyday language, making 'risk' a more suitable choice.

Correct answer: similar

Explanation: The word 'similar' is the correct choice as it indicates a likeness in circumstances, which is essential for the comparison being made. It fits grammatically as an adjective that describes the noun 'circumstances' and logically connects the two scenarios being discussed.

Meaning: 'Similar' means having a resemblance or likeness, indicating that the conditions under which one would expect help are alike.

Wrong options:

• other: 'Other' does not provide a comparative context and is too vague to describe the relationship between the circumstances.
• same: While 'same' could work, it implies exactness rather than the broader comparison that 'similar' suggests, which is more fitting here.
• different: 'Different' contradicts the intended meaning of comparing circumstances, making it unsuitable in this context.

Correct answer: selfish

Explanation: The word 'selfish' is appropriate as it encapsulates the idea that all actions may ultimately be driven by self-interest. It fits grammatically as an adjective that describes 'actions' and aligns with the cynical viewpoint being presented in the sentence.

Meaning: 'Selfish' means concerned excessively or exclusively with oneself, indicating that the actions may not be as altruistic as they seem.

Wrong options:

• motivated: While 'motivated' could imply a reason behind actions, it does not carry the same negative connotation of self-interest that 'selfish' does, making it less suitable.
• bad: 'Bad' is too general and does not specifically address the nature of self-interest in actions, lacking the nuance required in this context.
• deceitful: 'Deceitful' implies dishonesty, which does not directly relate to the concept of self-interest and is therefore not an appropriate fit.
