Correct Sentence Sequence
Final Sentence:
Individuals with a high BMI and a genetic susceptibility to obesity exhibit a reduced risk of heart disease when contrasted with those whose excess weight stems solely from environmental and lifestyle influences.
Correct Sequence:
(B) → (A) → (D) → (C) – ✔ Option 3
Explanation of Each Segment:
- (B): Establishes the subject group – "People with a high BMI and a genetic predisposition to obesity..."
- (A): Presents the primary finding – "...have a lower risk of heart disease..."
- (D): Introduces a comparative element – "...compared to people whose extra weight..."
- (C): Concludes the comparison – "...is related to environmental and lifestyle factors alone."
Why the Other Options Are Incorrect:
- (A), (B), (C), (D): ✖️ Commences with a verb phrase lacking a clear subject, leading to ambiguity.
- (A), (C), (B), (D): ✖️ Disrupts logical progression, creating incoherence between clause relationships.
- (C), (B), (D), (A): ✖️ Begins with a subordinate clause, lacking initial context and clarity.
Summary:
The sentence follows a logical structure: it begins by identifying the subject group (individuals with genetic predisposition and high BMI), proceeds to the health outcome (reduced risk), and then contrasts them with another group (those affected by environmental/lifestyle factors). This coherent flow is exclusively maintained in Option 3: (B), (A), (D), (C).
