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 FIFTH sentence after rearrangement?

The correct answer is Option B.

To determine the correct sequence of the sentences to form a coherent paragraph, let us analyze the context and logical connection between each sentence:

1. First Sentence: Sentence (C) introduces the topic of the paper and reports the discovery of a nearby free-floating planet located 1,560 light-years from Earth ("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) details the specific characteristics of this newly discovered rogue planet ("This wandering body, designated Rogue-9, is about 10 times the mass of Jupiter and orbits a dwarf star."). The phrase "This wandering body" directly refers to the "free-floating planet" mentioned in sentence (C).

3. Third Sentence: Sentence (A) provides additional significance to the discovery ("Furthermore, because this rogue planet does not emit any light of its own, locating it represents a major scientific breakthrough."). The transition word "Furthermore" builds upon the description in sentence (E).

4. Fourth Sentence: Sentence (D) places this discovery into context relative to potential undiscovered planets ("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) broadens the discussion to the broader population of rogue planets in our galaxy, serving as a concluding observation ("Researchers estimate that there are about 100 million rogue planets in the Milky Way, but almost all of them are invisible.").

Thus, the logical sequence of the paragraph is C - E - A - D - B.

The FIFTH sentence after rearrangement is sentence (B).
