Rearrange the following sentences to form a meaningful passage:
1. Carbon nanotubes exhibit exceptional strength and conductivity. 2. Their nanoscale diameter allows structural flexibility.3. Applications span electronics, medicine, and materials. 4. They're synthesized using chemical vapor deposition.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1-2-4-3.
Logical Sequence Analysis:
-
Sentence 1 (The Definition): This sentence introduces the subject (Carbon nanotubes) and defines their most significant properties (strength and conductivity).
-
Sentence 2 (Structural Detail): This follows the introduction by explaining the structural reason (nanoscale diameter) behind the properties mentioned in the first sentence.
-
Sentence 4 (The Process): After establishing what they are and how they are structured, this sentence describes how they are created (synthesized using chemical vapor deposition).
-
Sentence 3 (The Application): This serves as the conclusion, moving from the specific material and its production to its broad usage in various fields like electronics and medicine.
Final Logical Passage: Carbon nanotubes exhibit exceptional strength and conductivity. Their nanoscale diameter allows structural flexibility. They're synthesized using chemical vapor deposition. Applications span electronics, medicine, and materials.
Hence, the sequence 1-2-4-3 is correct.
