The answer is D: Asking journalistic questions (who, what, where, when, why, how).
Explanation for each option:
A. Discussing your topic with friends - This is not an on-the-page prewriting activity. It involves verbal communication and brainstorming, which can be helpful but does not involve writing on the page.
B. Recording your thoughts on a voice recorder (freetalking) - This is also not an on-the-page prewriting activity. It involves speaking and recording your ideas, which can later be transcribed, but the activity itself is not done on the page.
C. Visiting a writing lab on campus - This is a supportive activity where you might receive feedback or guidance, but it is not an on-the-page prewriting activity. It involves seeking external help rather than engaging in writing directly.
D. Asking journalistic questions (who, what, where, when, why, how) - This is an on-the-page prewriting activity. It involves writing down questions and answers to help structure and develop your ideas, which directly contributes to the writing process.
