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

A

, from New York to Los Angeles,

B

from New York to Los Angeles

C

—from New York to Los Angeles,

D

—from New York to Los Angeles—

Correct Answer: D

Choice D is the best answer. This question tests dash usage for emphatic parenthetical information.

  1. Context clues: The phrase adds emphasis to show the geographic range.
  2. Meaning: Dashes must be used in pairs when setting off emphatic interruptions.
  3. Verify: "Every major city in the country—from New York to Los Angeles—experienced..." adds emphasis correctly.

💡 Strategy: Use matching dashes to set off parenthetical information you want to emphasize.

Choice A is incorrect because commas don't provide the same emphasis. Choice B is incorrect because some punctuation is needed. Choice C is incorrect because dashes must be paired.
