The final sentence after adding a semi-colon and a comma to the given sentence will be written as: "I finally made it to my 8 am class on time; unfortunately, I left my textbook at home."
To correct the sentence, add a semi-colon (;) before the word "unfortunately" to connect the two independent clauses. A semi-colon is used when two closely related independent clauses are joined without a coordinating conjunction. Also add a comma (,) after "unfortunately" to separate the contrasting ideas within the second clause.
This helps improve the clarity of the sentence by indicating the pause between the ideas. The revised sentence now maintains a proper balance between the two clauses, making the connection more seamless and grammatically correct.
Therefore, this is how the final answer will look like: "I finally made it to my 8 am class on time; unfortunately, I left my textbook at home."
