Meaning: 'Revealed' means to make something known or visible that was previously hidden or unknown.

Wrong options:

• displayed: 'Displayed' suggests showing something openly, but it lacks the connotation of uncovering a secret, making it less suitable here.
• exhibited: 'Exhibited' implies a formal presentation, which does not match the context of a confession revealing a fact.
• unlocked: 'Unlocked' typically refers to opening a physical lock or metaphorically revealing something, but it is not commonly used in this context.

Correct answer: featured

Explanation: The word 'featured' is appropriate as it indicates that the photograph prominently included the serpent-like head, fitting the context of describing its content. It is in the past tense, matching the narrative flow.

Meaning: 'Featured' means to have something as a prominent part or characteristic, indicating that the serpent-like head was a key element of the photograph.

Wrong options:

• imagined: 'Imagined' suggests a creation of thought rather than a depiction in a photograph, making it contextually incorrect.
• illustrated: 'Illustrated' implies a drawing or representation, which does not accurately describe a photograph's content.
• visualised: 'Visualised' refers to forming a mental image, which does not fit the context of a physical photograph.

Correct answer: heavily

Explanation: The word 'heavily' fits grammatically as it modifies the verb 'disguised,' indicating the extent to which the toy submarine was disguised. It conveys a strong degree of disguise, aligning with the context.

Meaning: 'Heavily' means to a great degree or extent, suggesting that the toy submarine was very well disguised.

Wrong options:

• strongly: 'Strongly' typically refers to intensity or force, which does not appropriately modify 'disguised' in this context.
• severly: 'Severely' implies a harsh or serious condition, which does not fit the context of disguise.
• poerfully: 'Poerfully' appears to be a misspelling of 'powerfully,' which suggests strength but does not convey the degree of disguise needed here.

Correct answer: setback

Explanation: The word 'setback' is suitable as it indicates a hindrance or obstacle, which aligns with the context of disappointment for the monster's fans. It fits grammatically and contextually within the sentence.

Meaning: 'Setback' refers to a reversal or hindrance in progress, indicating that the revelation was disappointing for fans.

Wrong options:

• downfall: 'Downfall' implies a complete failure or collapse, which is too extreme for the context of a disappointment.
• drawback: 'Drawback' suggests a disadvantage but lacks the emotional weight of 'setback' in this context.
• stopgap: 'Stopgap' refers to a temporary solution, which does not fit the context of a disappointment.

Correct answer: tell

Explanation: The word 'tell' is appropriate as it indicates the act of communicating information, fitting the context of revealing the truth about the photographs. It is in the base form, suitable for the future tense construction.

Meaning: 'Tell' means to communicate or inform someone about something, indicating that time will reveal the truth.

Wrong options:

• say: 'Say' is a more general term for speaking but does not convey the same sense of information being revealed as 'tell.'
• no: 'No' is a negation and does not fit grammatically or contextually in this sentence.
• admit: 'Admit' implies acknowledging something, which does not align with the context of time revealing information.

Correct answer: genuine

Explanation: The word 'genuine' fits grammatically and contextually as it describes the authenticity of the photographs, aligning with the inquiry about their truthfulness. It is an adjective that complements the noun 'photographs.'

Meaning: 'Genuine' means authentic or real, indicating that the photographs may or may not be true representations.

Wrong options:

• truthful: 'Truthful' refers to being honest but does not specifically address the authenticity of the photographs as 'genuine' does.
• honest: 'Honest' implies truthfulness in character, which does not directly relate to the nature of the photographs.
• sincere: 'Sincere' refers to genuine feelings or expressions, which does not fit the context of discussing the authenticity of photographs.
