However, to get accurate and useful results, users need to write clear and effective prompts. At the same time, they must be aware of ethical issues such as bias, privacy violations, and the misuse of AI-generated content. i. Explain the importance of prompt engineering in obtaining effective results from AI tools. ii. How can users reduce ethical risks when using AI tools? | 2+2 | CO2
