Which of the following prefixes implies duplication when attached to a root word?

In this sentence, the preposition "at" is followed by its object, which is "the clown." The object of the preposition is the noun or pronoun that follows the preposition and relates to the rest of the sentence.

The conjunction in this sentence is "and," which connects two independent clauses, indicating a relationship between the actions of finishing mowing the lawn and taking a long nap.

This sentence uses correct capitalization by capitalizing the first letter of "The Red Cross" as a proper noun, and the first letter of the sentence. Additionally, it follows proper capitalization rules for the names of organizations and titles.

"Furthermore" is a transitional expression used to add information in a logical sequence. While "nevertheless" indicates contrast, "elsewhere" indicates location, and "similarly" indicates comparison, "furthermore" is the best choice for showing the progression of ideas.

The prefix "inter-" implies the idea of between or among, often indicating a relationship or interaction between two or more things.

This sentence uses commas correctly. The appositive phrase ("a first-generation German-American") is properly set off with commas to provide additional information about Dorothes Lange. Commas are also correctly used in the list of social issues: "poverty, racism, and migration." Proper comma usage improves clarity and readability.

A complex-compound sentence consists of at least two independent clauses and one or more dependent clauses. Sentence A correctly connects an independent clause ("The Honey Island Swamp is beautiful") with a dependent clause ("when you're here, you'll see why we love it") using a semicolon, making it grammatically sound. The other options contain errors in punctuation and sentence structure.

The prefix "post-" indicates something that comes after or is subsequent to a particular event or time. It is often used to denote a sequence of events.

The prefix "mis-" means "incorrectly" or "badly." "Misalign" refers to aligning something incorrectly. Prefixes change the meaning of root words. For example, if car wheels are "misaligned," they are improperly positioned, potentially affecting driving performance. The other options contain prefixes with different meanings, such as "ir-" for "not" and "down-" indicating a reduction.

Receive is the only correctly spelled word.
