SAT Grammar Practice Quiz: Modifier Placement

Welcome to Quiz Your English! Today we are focusing on one of the most frequently tested concepts on the Digital SAT: Modifier Placement.

What is a Modifier?

A modifier is a word, phrase, or clause that describes or gives more information about another word in the sentence. On the SAT, you will frequently encounter "dangling modifiers." This happens when an introductory descriptive phrase is placed next to the wrong noun.

The Golden Rule for SAT Modifiers: The exact noun being described MUST appear immediately after the comma following an introductory modifier.

Detailed Explanations

Why A is correct

• The opening modifier "Composed of clay and silicate rocks" must describe the noun immediately after the comma.
• Choice A places "C-type asteroids" directly after the modifier, which is exactly what is composed of those materials.
• The main clause is complete: "C-type asteroids ... are typically dark in appearance."

Why the others are incorrect

• B. asteroids, such as the C-type asteroids... → The generic noun "asteroids" is too broad; the modifier is specifically describing C-type asteroids, not asteroids in general.
• C. the C-type classification applies to... → The modifier would describe "the C-type classification," but a classification cannot be composed of clay and silicate rocks.
• D. 93 Minerva and 45 Eugenia are classified... → The inserted clause disrupts the sentence and makes the introductory modifier attach incorrectly.

Takeaway After an introductory modifier, the exact noun being described should appear immediately after the comma.
