This sentence misuses a colon. Colons are used to combine two clauses when the second clause explains the whole- or something about the first clause. This sentence is a simple sentence, so there is only one clause present. Colons are never just placed before a preposition, unless that preposition begins a new clause (which is not happening here), and they never come after a preposition, as that would split the prepositional phrase. The correct choice is, "plan for the employees to follow in times of chaos."

Colons are often used to introduce quotations; however colons used in this fashion cannot follow a verb (like "shouted"). In this sentence the colon should be replaced with a comma. Direct quotations (including punctuation) must be enclosed in quotation marks.

This sentence misuses a colon. Colons are used to join two separate clauses, when the second clause explains the whole- or something about the first clause.

The correct choice is, "Damian's shares for 600 million dollars."

This sentence misuses a colon. Colons are used to join two separate clauses, when the second clause explains the whole- or something about the first clause.

This sentence contains a colon where one is not necessary. Colons are used to join two clauses when the second clause explains something about the first clause. Colons are not used with conjunctions like "because," though. Furthermore, the word "because" does not need a comma before it (only coordinating conjunctions need a comma before it when joining an independent clause to another. The correct choice is, "The teacher's rates were high because his students."

This sentence contains an error in the usage of the colon. Colons are used to join two clauses when the second clause explains something in the first clause. The colons in the choices above, however, only split up the existing clauses (Colons never are used in the middle of clauses and absolutely never after a preposition like "of"). The best choice is to omit the colon. The correct answer is, " in order to achieve his goal of becoming a pro skater."

This sentence misuses the colon. Colons are used to join two clauses (the first one has to be independent) when the second clause explains/describes something about the first clause.

This sentence does not contain a colon where necessary. The phrase "The Grapes of Wrath, Animal Farm, and To Kill A Mockingbird" describe exactly what books the subject plans to read. Colons should be used when combining two related clauses when the second clause explains something about the first one; therefore, a colon should appear after the word "vacation." The correct choice is, "books during his vacation: The Grapes of Wrath, Animal Farm, and To Kill A Mockingbird."

This sentence has misplaced the colon. The colon should come after the word "include" since that word marks the end of the first clause. Note that colons combine two clauses when the second one explains or describes something about the first clause. The correct choice is, "market caps on the stock market include: Roundree, Gargle, and Mousecow."

This sentence uses a colon where one is not necessary. Colons are used to join two clauses when the second clause describes something about the first clause.
