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

A. allow
B. allowing✓ Correct
C. allows
D. allowed

Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. The original has a comma splice. 'Allowing' as a participle creates a participial phrase that modifies 'revolutionized communication' and avoids the comma splice. 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:

• "revolutionized communication"

• "people to speak in real-time"

Why others are wrong: A ('It allow' is grammatically incorrect and creates a comma splice.), C ('It allows' creates a comma splice and mixes past and present tense.), D ('It allowed' creates a comma splice between two independent clauses.).
