Answer and Explanation:
To determine the percentage of twelfth-graders who report using an illicit drug at least once each week and the percentage who report using an illicit drug daily, we need specific data or statistics related to the drug usage among twelfth-graders. Without this information, it is not possible to provide an accurate answer.
The percentage of twelfth-graders using drugs can vary widely based on factors such as location, time period, and survey methodology. It is essential to refer to reliable and up-to-date sources such as government surveys or reputable research studies to obtain accurate information on drug usage among twelfth-graders.
