Which choice completes the text so that it conforms to the conventions of Standard English?

A. day:
B. day,✓ Correct
C. day;
D. day

Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. A comma is needed before the participial phrase 'pumping blood.' This phrase adds information about how the heart functions. Each sentence in a well-constructed text serves a specific purpose. Consider what role this sentence plays in the argument: does it introduce, support, contrast, or conclude an idea? Understanding why an author includes specific sentences helps you grasp the overall argument. Each sentence should serve a clear purpose: introducing ideas, providing evidence, acknowledging counterarguments, or drawing conclusions. Identify the role to understand the structure.

Key Evidence:

• "100,000 times per _______"

• "pumping blood throughout the body"

Why others are wrong: C (A semicolon separates independent clauses; 'pumping blood...' is a phrase.), A (A colon introduces lists or explanations, not participial phrases.), D (Without punctuation, the sentence runs together incorrectly.).
