Set 14: Form, Structure & Sense
Explanation
PASSAGE
Honeybees communicate the location of food sources through a series of movements known as the 'waggle dance.' _______ allows other bees in the hive to find nectar efficiently.
Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
This question tests your understanding of sentence function and text organization. 'This' is a demonstrative pronoun that refers back to the entire concept of the waggle dance. It correctly begins a new sentence that explains why the dance is important. 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:
• "the 'waggle dance'"
• "allows other bees"
Why others are wrong: B ('It' is less clear as a reference; 'This' better refers to the concept just described.), D ('They' is plural and creates unclear reference to either bees or movements.), C ('These' is plural and doesn't match the singular 'dance.').
