(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 and arrange the given sentence fragments logically to form a coherent, grammatically correct sentence:

1. Part (A): "NASA's Artemis II crew splashed" introduces the main subject of the sentence ("NASA's Artemis II crew") and the beginning of the verb phrase ("splashed").

2. Part (B): "down safely in the Pacific, completing" completes the phrasal verb "splashed down" ("splashed down safely in the Pacific") and introduces a participle phrase ("completing..."). Therefore, Part (B) naturally follows Part (A).

3. Part (D): "the first human journey" acts as the direct object of the action participle "completing" ("completing the first human journey..."). Thus, Part (D) logically follows Part (B).

4. Part (C): "around the Moon in over 50 years" acts as a prepositional modifier describing the journey ("the first human journey around the Moon in over 50 years"). Thus, Part (C) finishes the sentence after Part (D).

Putting it all together, we get the complete meaningful sentence:

"NASA's Artemis II crew splashed down safely in the Pacific, completing the first human journey around the Moon in over 50 years."

This sequence corresponds to A - B - D - C (ABDC).
