Set 9: Form, Structure & Sense (Intermediate)
Explanation
PASSAGE
The planet Mars, often called the 'Red Planet,' _______ two small moons named Phobos and Deimos.
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. 'The planet Mars' is singular (the phrase 'often called the Red Planet' is parenthetical). The singular subject requires 'has' in present tense for a current fact. 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 planet Mars"
• "two small moons"
Why others are wrong: A ('Had' implies Mars no longer has these moons; this is a current fact.), D ('Have' is plural; 'Mars' is singular.), B ('Having' is a participle; the sentence needs a main verb.).
