Meaning: 'Trip' means a journey or excursion to a particular place, often for a specific purpose.

Wrong options:

• expedition: 'Expedition' implies a journey undertaken for a specific purpose, often involving exploration, which does not fit the casual context of visiting Germany for exchange.
• way: 'Way' refers to a method or manner of doing something, not a journey, making it grammatically incorrect in this context.
• break: 'Break' typically refers to a pause or interruption, not a journey, thus it does not fit the context of traveling.

Correct answer: been

Explanation: The word 'been' is the correct past participle of 'be,' which is required here to indicate that the speaker has experienced the trip in the past. It fits grammatically as part of the present perfect tense, which is used to describe experiences.

Meaning: 'Been' is the past participle of 'be,' used here to indicate that the speaker has had the experience of going on the trip.

Wrong options:

• got: 'Got' is the past tense of 'get,' which does not convey the experience of having gone on a trip, making it contextually inappropriate.
• brought: 'Brought' is the past tense of 'bring,' which implies carrying something to a place, not applicable in the context of describing a trip.
• get: 'Get' is the base form of the verb and does not fit grammatically in the past context of the sentence.

Correct answer: land

Explanation: The word 'land' is appropriate here as it refers to the act of an aircraft arriving on the ground, which is relevant to the context of flights and travel. It fits grammatically as a noun that describes the location where the plane arrives.

Meaning: 'Land' means the area of ground where an aircraft arrives, making it suitable in the context of discussing flights.

Wrong options:

• place: 'Place' is a general term that does not specifically refer to the act of an aircraft arriving, making it less precise in this context.
• area: 'Area' is too vague and does not convey the specific action of landing, thus it does not fit the context of aviation.
• space: 'Space' refers to a physical expanse and does not relate to the context of an aircraft arriving, making it inappropriate.

Correct answer: another

Explanation: The word 'another' is the correct choice as it indicates an additional hour, which fits the context of time being discussed. It is grammatically correct as it modifies the noun 'hour' to indicate one more of the same kind.

Meaning: 'Another' means one more in addition to what has already been mentioned, suitable for indicating additional time.

Wrong options:

• other: 'Other' implies a different one, which does not fit the context of adding time to what has already been mentioned.
• big: 'Big' describes size and does not relate to the concept of time, making it irrelevant in this context.
• next: 'Next' refers to the following in a sequence, which does not fit the context of adding time to the current situation.
