A.I. Explanation:

Correct answer: stood

Explanation: The word 'stood' fits grammatically as it is the past tense of 'stand,' which in this context means to be in a favorable position or to be advantageous. It aligns with the phrase 'in good stead,' indicating that the expertise was beneficial for organizing the journey.

Meaning: 'Stood' in this context means to have been in a position that is advantageous or beneficial, suggesting that the expertise was helpful.

Wrong options:

• kept: 'Kept' implies maintaining possession or continuing something, which does not fit the context of being in a favorable position.
• took: 'Took' suggests an action of grabbing or seizing, which does not convey the idea of being in a beneficial position.
• made: 'Made' indicates creation or formation, which does not align with the concept of being in good stead.

Correct answer: alone

Explanation: The word 'alone' correctly emphasizes the rarity of the situation, indicating that few civilians had even traveled to Egypt, let alone along the Nile. It fits grammatically and contextually as it highlights the exclusivity of the experience.

Meaning: 'Alone' means without others, emphasizing that it was an exceptional circumstance for civilians to travel along the Nile.

Wrong options:

• apart: 'Apart' suggests separation but does not convey the same exclusivity or rarity as 'alone.'
• aside: 'Aside' implies setting something to the side, which does not fit the context of traveling.
• away: 'Away' indicates distance but does not capture the exclusivity of the experience as 'alone' does.

Correct answer: going

Explanation: The word 'going' fits well as it indicates movement through time, suggesting that the history and civilization are continuously present. It aligns with the context of the sentence, which discusses the historical significance of the Nile.

Meaning: 'Going' in this context refers to the ongoing nature of history, indicating that it has been present for thousands of years.

Wrong options:

• flowing: 'Flowing' suggests a physical movement of water, which does not fit the abstract concept of history.
• running: 'Running' implies a continuous action but does not convey the historical aspect as effectively as 'going.'
• passing: 'Passing' suggests something transient, which does not align with the enduring nature of history.

Correct answer: world

Explanation: The word 'world' fits grammatically and contextually as it refers to the global scope of travel, indicating that the tour organized by Cook had a significant impact on travel worldwide.

Meaning: 'World' refers to the global community or the entirety of travel, suggesting a broad influence on how travel is perceived and conducted.

Wrong options:

• scene: 'Scene' refers to a specific location or view, which does not encompass the broader concept of travel.
• area: 'Area' suggests a specific region, lacking the global implication that 'world' provides.
• land: 'Land' refers to physical territory, which does not capture the comprehensive nature of travel as 'world' does.

Correct answer: been

Explanation: The word 'been' is the correct past participle form of 'be,' fitting grammatically in the present perfect tense used here to indicate that travel has not changed since that time. It aligns with the context of continuity in travel.

Meaning: 'Been' indicates existence or occurrence in the past, suggesting that travel has remained unchanged since Cook's tour.

Wrong options:

• be: 'Be' is the base form of the verb and does not fit grammatically in this context where a past participle is required.
• as: 'As' is a conjunction or preposition that does not fit the grammatical structure needed here.
• for: 'For' is a preposition that does not convey the meaning of existence or occurrence, making it unsuitable.
