Explanation:

For Question 5:

• Option A has incorrect comma placement that breaks the sentence incorrectly.
• Option B uses a comma and coordinating conjunction "and" to correctly join two independent clauses, making the sentence clear.
• Option C uses a semicolon to correctly join two closely related independent clauses, which also improves clarity.
• Thus, both B and C are valid revisions.

For Question 6:

• Option A lacks commas between items in the series, creating a run-on list.
• Option B correctly uses commas to separate all items in the series, including the Oxford comma before "and" which follows standard grammatical rules for clear series formatting.
• Option C is missing a comma between the first two items in the series.
• Option D incorrectly places a comma right after the verb "covered", which disrupts the sentence structure.

Answer:

Question 5: D. Both B and C are correct.
Question 6: B. The lesson covered grammar, punctuation, and structure.
