The correct option to complete the sentence is
A. touched down.
Step-by-Step Explanation:
-
Understanding the Context: The sentence describes an event that occurs after a long flight. The phrase "As luck would have it" suggests a positive turn of events, which is further emphasized by the mention of the weather brightening. The sentence is likely referring to the moment when an airplane lands.
-
Analyzing the Options:
- A. touched down: This phrase is a common aviation term that specifically means to land an aircraft. It conveys the idea of the plane making contact with the runway, which is the appropriate action after a flight.
- B. dropped: While "dropped" can imply a descent, it is not a standard term used in aviation to describe landing. It could suggest a sudden or uncontrolled descent, which does not fit the context of a safe landing at an airport.
- C. came down: This phrase is somewhat vague. While it can refer to descending or landing, it lacks the specificity and formality of "touched down." It does not convey the same sense of a completed landing as effectively as option A.
-
D. flew down: This option suggests that the plane is still in the process of flying downwards, which does not indicate that the plane has landed. It implies ongoing action rather than the completion of the flight.
-
Why Option A is Correct: "Touched down" is the most suitable choice because it is the precise term used in aviation to indicate that an aircraft has landed safely on the runway. It fits perfectly with the context of the sentence, which describes the conclusion of a flight.
-
Why Other Options are Incorrect or Weaker:
- B. dropped: This term could imply a negative connotation, suggesting a lack of control or a sudden descent, which is not appropriate in the context of a safe landing.
- C. came down: While it can refer to landing, it is less formal and specific than "touched down." It does not convey the same level of certainty about the landing process.
- D. flew down: This option suggests that the plane is still in the process of descending, which does not complete the action of landing. It implies that the flight is ongoing rather than finished.
Revision Summary:
- The correct answer is A. touched down, which means the plane has landed.
- "Touched down" is a specific aviation term that indicates a safe landing.
- Other options like "dropped," "came down," and "flew down" are either vague or imply ongoing action rather than completion.
- Understanding the context and specific terminology is crucial for selecting the most appropriate option in such sentences.
