Rearrange the given parts to form a meaningful sentence.

(A) understanding of the universe uncovering mysteries

(B) space exploration has expanded humanity's

(C) technological innovations, that benefit life on Earth

(D) about planets, stars and galaxies while inspiring

Choose the correct answer from the options given below:

Solution

✅ Correct Option: 2

Option 1 -> Starts with "understanding of the universe" which lacks a subject and verb to begin the sentence - grammatically incorrect.

Option 2 -> Begins with "Space exploration has expanded humanity's" (subject + verb), followed by "understanding of the universe uncovering mysteries about planets, stars and galaxies while inspiring technological innovations, that benefit life on Earth" - creates a complete, logical sentence.

Option 3 -> Starts with "about planets, stars and galaxies while inspiring" which is a prepositional phrase that cannot begin a complete sentence.

Option 4 -> Also starts with a prepositional phrase "about planets, stars and galaxies while inspiring" making it an incomplete sentence structure.


Hence, Option 2: (B), (A), (D), (C) -> The sentence reads: "Space exploration has expanded humanity's understanding of the universe uncovering mysteries about planets, stars and galaxies while inspiring technological innovations, that benefit life on Earth" - this follows proper sentence structure with a clear subject (space exploration), main verb (has expanded), and logically connected clauses that express a complete thought about space exploration's dual impact. -> correct
