(B) down safely in the Pacific, completing

(D) the first human journey

The following question gives a sentence which has been divided into four parts which may not be in their correct order of narrative. The sentence is then followed by five options, one of which gives the sequence of the rearranged parts to make the sentence meaningful. Choose the option which gives the correct sequence of the parts. If the sentence is already arranged in the correct sequence, mark option " No rearrangement required " as the answer.

The correct option is ABDC.

Let's analyze the given parts step-by-step to reorder them into a coherent and grammatically correct sentence:

1. Part (A): "NASA's Artemis II crew splashed"
This serves as a natural introduction/subject of the sentence, introducing the Artemis II crew and initiating the main verb "splashed".

2. Part (B): "down safely in the Pacific, completing"
This naturally follows Part (A) because "splashed" combines with "down" to form the phrasal verb "splashed down" (splashed down safely in the Pacific). The participle "completing" introduces what action was completed.

3. Part (D): "the first human journey"
The verb/participle "completing" requires a direct object. "the first human journey" acts as the object of "completing".

4. Part (C): "around the Moon in over 50 years"
This prepositional phrase modifies "the first human journey", specifying where and when the journey took place ("around the Moon in over 50 years").

Putting the sequence together: (A) NASA's Artemis II crew splashed (B) down safely in the Pacific, completing (D) the first human journey (C) around the Moon in over 50 years.

Thus, the correct sequence is ABDC.
