Show answer & explanation
Correct answer: A
Explanation
Correct Answer: B – C – A – D
Explanation
• Sentence B is the ideal opening sentence as it introduces the central subject, defining what 'biohacking' is.
• Sentence C naturally follows B because the demonstrative phrase 'This trend' refers back to the biohacking movement introduced in sentence B.
• Sentence A introduces a contrast regarding biohacking practices—mentioning both performance enhancement and safety concerns.
• Sentence D follows A with the conjunction 'However', expanding specifically on the safety concerns by explaining the risks tied to the lack of medical oversight.
Quick Tip: Identify the introductory sentence that defines the topic first, then trace pronoun or demonstrative references (like 'This trend') to find mandatory pairs.
