A.I. Explanation:

Correct answer: popping

Explanation: The word 'popping' fits grammatically as a present participle that describes the action of new branches emerging frequently. It aligns contextually with the idea of supermarkets appearing rapidly, suggesting a lively and informal tone.

Meaning: 'Popping' means to appear suddenly or unexpectedly, often used to describe something that happens quickly and frequently.

Wrong options:

• leaping: While 'leaping' implies a sudden movement, it is less commonly used in this context and suggests a more dramatic action than simply appearing.
• jumping: Similar to 'leaping', 'jumping' conveys a sense of suddenness but lacks the casual connotation that 'popping' provides in this context.
• nipping: 'Nipping' suggests a quick, small action, but it does not convey the idea of frequent emergence as effectively as 'popping'.

Correct answer: superfluous

Explanation: The term 'superfluous' is appropriate here as it indicates that the celebrity's presence is unnecessary due to the abundance of alternatives. It fits grammatically and contextually, emphasizing the shift in societal norms regarding supermarket openings.

Meaning: 'Superfluous' means unnecessary or more than enough, indicating that the celebrity is no longer needed for these events.

Wrong options:

• excessive: 'Excessive' implies an overabundance but does not convey the same sense of being unnecessary as 'superfluous'.
• surplus: While 'surplus' refers to an excess amount, it is more commonly used in economic contexts and does not fit the social commentary of the sentence.
• residual: 'Residual' suggests something remaining after a process, which does not align with the idea of being unnecessary in this context.

Correct answer: as long as

Explanation: The phrase 'as long as' introduces a condition that emphasizes the importance of being at the front rather than who is opening the store. It fits grammatically and contextually, indicating a focus on the attendees' priorities.

Meaning: 'As long as' means 'provided that' or 'on the condition that', highlighting the condition under which the pensioners are satisfied.

Wrong options:

• despite: 'Despite' indicates a contrast, which does not fit the conditional nature of the sentence.
• in case: 'In case' suggests a precautionary measure, which does not align with the certainty expressed in the sentence.
• regardless: 'Regardless' implies indifference, but it does not convey the conditional aspect that 'as long as' does.

Correct answer: threshold

Explanation: The word 'threshold' is the most suitable choice as it refers to the entrance or starting point of a place, fitting both grammatically and contextually within the sentence about the supermarket's entry.

Meaning: 'Threshold' means the entrance or the point of beginning, particularly in a physical context like a doorway.

Wrong options:

• entrance: While 'entrance' is a synonym, it is less specific than 'threshold', which implies a more defined point of entry.
• doorway: 'Doorway' refers to the physical structure but lacks the metaphorical nuance of 'threshold' as a point of opportunity.
• barrier: 'Barrier' suggests an obstruction, which is contrary to the idea of welcoming customers into the supermarket.

Correct answer: snippet

Explanation: The term 'snippet' is appropriate as it refers to a small portion of information, fitting grammatically and contextually within the sentence about the information being shared among the crowd.

Meaning: 'Snippet' means a small piece or extract, particularly of information, indicating that the details shared were brief but significant.

Wrong options:

• clipping: 'Clipping' typically refers to a cut-out piece of material, which does not convey the idea of information as effectively as 'snippet'.
• strand: 'Strand' usually refers to a single thread or element, which does not fit the context of information sharing.
• string: 'String' implies a series of connected items, which does not accurately represent the singular piece of information being discussed.

Correct answer: through

Explanation: The word 'through' is the best fit as it indicates movement within a space, aligning grammatically and contextually with the idea of information spreading among the crowd.

Meaning: 'Through' means moving in one side and out of the other, suggesting that the information circulated widely among the people present.

Wrong options:

• among: 'Among' suggests being in the midst of a group but does not convey the sense of movement that 'through' does.
• across: 'Across' implies a surface-level movement, which does not capture the idea of information permeating the crowd as effectively as 'through'.
• around: 'Around' suggests a circular movement, which does not accurately reflect the dissemination of information in this context.
