In a presentation, background information is typically provided in the opening part. Here's why:
1. **Opening**: This is where you set the stage for your presentation. It's important to establish context by providing background information to help the audience understand the topic you will be discussing. This could include why the topic is important, relevant, or timely.
2. **Example**: If you are giving a presentation on climate change, in the opening part you might provide background information about the causes and effects of climate change, statistics to highlight its impact, and the urgency of taking action.
3. **Thoughtful question or interesting fact**: While background information is crucial in the opening, you can also incorporate a thoughtful question or an interesting fact to engage your audience right from the start. This can help create interest and grab attention.
Therefore, the correct answer is: **Opening**. This is where you should provide background information, ask a thoughtful question, or share an interesting fact to captivate your audience and set the tone for the rest of your presentation.
