Rearrange the following sentences (A), (B), (C), (D), and (E) to form a coherent paragraph, then answer the question.

(A) Furthermore, because this rogue planet does not emit any light of its own, locating it represents a major scientific breakthrough.
(B) Researchers estimate that there are about 100 million rogue planets in the Milky Way, but almost all of them are invisible.
(C) A recently published paper reveals that the nearest free-floating planet discovered is located only 1,560 light-years from Earth, a new study reports.
(D) Although this particular world is the closest rogue planet detected so far, it is highly unlikely to be the nearest one in existence.
(E) This wandering body, designated Rogue-9, is about 10 times the mass of Jupiter and orbits a dwarf star.

Which of the following will be the FOURTH sentence after rearrangement?

The correct option is D.

To determine the correct order of the sentences and find the fourth sentence after rearrangement, let us analyze the logical connection between each sentence:

1. First sentence (Sentence C):
Sentence (C) introduces the primary subject of the paragraph: a newly discovered free-floating (rogue) planet located 1,560 light-years from Earth. It serves as the opening topic sentence.
"A recently published paper reveals that the nearest free-floating planet discovered is located only 1,560 light-years from Earth, a new study reports."

2. Second sentence (Sentence E):
Sentence (E) provides specific details about "this wandering body" (referring back to the free-floating planet introduced in C), giving its mass and orbit details.
"This wandering body, designated Rogue-9, is about 10 times the mass of Jupiter and orbits a dwarf star."

3. Third sentence (Sentence A):
Sentence (A) elaborates on why discovering this planet is significant ("Furthermore, because this rogue planet does not emit any light of its own..."), highlighting the scientific breakthrough.
"Furthermore, because this rogue planet does not emit any light of its own, locating it represents a major scientific breakthrough."

4. Fourth sentence (Sentence D):
Sentence (D) comments specifically on the distance aspect mentioned in C and elaborated upon, noting that while it is the closest detected so far, it is unlikely to be the absolute nearest one in existence.
"Although this particular world is the closest rogue planet detected so far, it is highly unlikely to be the nearest one in existence."

5. Fifth sentence (Sentence B):
Sentence (B) concludes the paragraph by broadening the scope to explain why even closer ones are hard to find—there are an estimated 100 million rogue planets in the Milky Way, but almost all are invisible.
"Researchers estimate that there are about 100 million rogue planets in the Milky Way, but almost all of them are invisible."

Complete Coherent Sequence:
(C) → (E) → (A) → (D) → (B)

Therefore, the FOURTH sentence after rearrangement is sentence (D).
