Answer: A possible correction that should be made to this sentence is to replace the comma with a semicolon.
Explanation: A comma is a punctuation mark that is used to separate words, phrases or clauses in a sentence. A comma can indicate a pause, a list, a conjunction, an appositive or a nonrestrictive modifier. However, a comma should not be used to join two independent clauses without a coordinating conjunction. An independent clause is a group of words that can stand alone as a complete sentence. A coordinating conjunction is a word that connects two independent clauses and shows their relationship. The most common coordinating conjunctions are for, and, nor, but, or, yet and so (FANBOYS).
In this sentence, there are two independent clauses: “Unless you are luckier than most” and “hundreds of other people will also have discovered your natural paradise”. These clauses are joined by a comma without a coordinating conjunction, which creates a comma splice. A comma splice is a grammatical error that occurs when two independent clauses are incorrectly joined by a comma.
A possible way to correct a comma splice is to replace the comma with a semicolon. A semicolon is a punctuation mark that is used to separate two independent clauses that are closely related in meaning but not joined by a coordinating conjunction. A semicolon can indicate a contrast, a transition or a balance between two clauses.
In this sentence, replacing the comma with a semicolon would create a correct sentence that shows the contrast between the condition of being lucky and the reality of finding other people in your natural paradise. The sentence would read: “Unless you are luckier than most; hundreds of other people will also have discovered your natural paradise.”
Hope this helps, and have a great day! =)
