PASSAGE

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

A. to include
B. they included
C. including✓ Correct
D. that included

Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. The sentence needs a participial phrase to modify 'conservation efforts.' 'Including' is a present participle that correctly introduces additional information about the efforts. 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:

• "Conservation efforts _______ the banning"

• "the species' resurgence"

Why others are wrong: B ('They included' creates a comma splice with an independent clause.), D ('That included' would need a relative clause structure; doesn't fit grammatically here.), A ('To include' suggests purpose, which doesn't make sense here.).
