Set 14: Form, Structure & Sense
Explanation
PASSAGE
Recent studies show that 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
[Variation 1] 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.').
