Explanation:

For Question 9:

A semicolon correctly joins two independent, related clauses.

• Option A: Uses a semicolon before a coordinating conjunction "and", which is incorrect (a comma should be used here instead).
• Option B: The semicolon separates a verb phrase from its adverbial modifier, which is incorrect.
• Option C: The semicolon is used before a subordinating conjunction "because", which is incorrect (no punctuation is needed here, or a comma in the reverse clause order).
• Option D: Joins two complete, related independent clauses ("The data was collected" and "the team analyzed it carefully") with a semicolon, which follows proper usage rules.

For Question 10:

A comma correctly follows an introductory prepositional phrase when it is long enough to create a natural pause.

• Option A: Places a comma after the introductory prepositional phrase "During the discussion", which is correct for readability.
• Option B: Omits the comma after the introductory phrase, creating a choppy flow.
• Option C: Misplaces the comma in the middle of the introductory phrase, breaking its meaning.
• Option D: Misplaces the comma between the subject "students" and verb "shared", which is grammatically incorrect.

Answer:

Question 9: D. The data was collected; the team analyzed it carefully.
Question 10: A. During the discussion, students shared different perspectives.
