Based on an analysis of word parts, which of the following affixes, if added to the nonsense root word "amell", would make the word have an opposite meaning?

A dangling modifier is a descriptive phrase that doesn't clearly and logically refer to a word in the sentence. In option B, "that needed paint" appears to describe the garage instead of the truck, making it a misplaced or dangling modifier that causes confusion about what needs paint.

Option D uses formal standard English without contractions or slang. The other options contain contractions or informal phrases less suitable for formal writing.

The thesis statement is your original idea or argument and does not require a citation. Summaries, charts, and theories taken from other works must be cited to credit the original sources.

Starting with 3 sets the scene, 4 introduces conflict, 2 shows the dog's reaction, and 1 provides a concluding statement. This order follows a logical chronological progression.

"Dogs" is plural and requires the plural verb "run," not "runs." The other sentences have correct agreement.

Option B correctly uses commas to separate the list and the nonrestrictive clause. The apostrophe in "United States'" indicates possession correctly. Other options misuse colons and semicolons or omit necessary commas.

"Affect" is a verb meaning to influence. "Effect" is usually a noun. Option C uses "affect" correctly as a verb.

The prefix "circum-" means "around," so adding it to "vent" (meaning to come or go) forms a word meaning to go around. Other prefixes don't convey "around."

A complex sentence contains an independent and at least one dependent clause, as in option B.

The introductory phrase "After reading the book" incorrectly modifies "the movie," which cannot read. The correct sentence should clarify who read the book.
