This sentence has a comma splice. This is when two independent clauses (clauses which can stand on their own as complete sentences) are separated only by a comma. A semicolon works well here. The corrected sentence reads, "The museum is hosting a Georgia O'Keefe exhibit until January; we should go this weekend."

This sentence is not coordinated correctly. The first clause explains why something is happening, so it shouldn’t be connected to the main clause with an “and.” The corrected sentence reads, "Due to global temperature increases, the polar ice cap is melting at an alarming rate."

This sentence is a fragment because it does not have a subject. Instead of starting out with the gerund ("-ing" verb used as a noun) “enjoying,” we need a subject and a verb that agrees with it. One example of how to correct this sentence would be, "I enjoy the sensation of standing in the warm rain and listening to it hit the pavement."

This sentence is a fragment; read it out loud and you will hear that it sounds incomplete. This happened because the "that" turned the main part of the sentence into a modifying phrase. Take this out to fix the fragment: "The cafeteria was serving "seafood surprise" for lunch and subsequently not attracting many customers."

In this sentence, the independent clauses "Virtue is, in many ways, a foreign idea to him" and "every kind gesture he thinks he knows is proven false" are linked with a comma. This is called a comma splice and should be avoided. Replacing the comma with a semicolon fixes the error.

"Even if he were to unknowingly live out the prophecy," is a dependent clause. It could be combined with the sentence before it, if a comma were placed after "wealthy," the period after "wealthy" is incorrect.

This sentence has some unnecessary words thrown in it. “It having been” is clunky and not needed. The corrected sentence reads: The old, faded rug ran the course of the entire empty room, left untouched for fifty years.

The error in this sentence is a split infinitive. Conventional grammar rules tell us that an infinitive verb, such as “to forget,” should not be interrupted by an adverb, like “silently.” It would be more correct to say "tried silently to forget.”

The error in the sentence is "I bought." The fact that I go to the store "every Wednesday" indicates that my actions, from going to the store to buying milk, are recurring actions. Using "I bought" makes the action a past action, when it should be "I buy." 

This sentence has a double negative, which is redundant. The corrected sentence reads: "Statistical evidence supports the claim that a majority of middle-aged men do not use deodorant."
