which revision best corrects the error in this sentence?
several key elements were missing from the movie, i noticed, after i read the book it was based on.
○ i noticed that several key plot elements were missing from the movie after i read the book it was based on.
○ after reading the book that the movie was based on, i noticed that the movie was missing several key plot elemen
○ i noticed, after i read the book it was based on, that several key plot elements were missing from the movie.

Explanation:

A dangling modifier occurs when the modifier (here, "After reading the book it was based on") doesn't clearly modify a subject. The correct revision should make it clear who read the book. Let's analyze each option:

• First option: Word order is confusing and doesn't fix the modifier issue properly.
• Second option: "I noticed that several key plot elements were missing from the movie after I read the book it was based on." Here, "I" is the subject who read the book, and the modifier now clearly relates to "I" (the one who read the book), and the sentence structure is clear.
• Third option: The structure is a bit convoluted and not as clear as the second option.
• Fourth option: The text is cut off and has structural issues.

So the best revision is the second option (the one starting with "I noticed that...").

Answer:

I noticed that several key plot elements were missing from the movie after I read the book it was based on.
