I'm unable to see the text or context needed to answer those questions directly. However, I can help you understand how to approach answering them! Here's a general guideline:

1. **What do Jack and his friends do outside?**
- Look for activities they enjoy, such as playing sports or hanging out.

2. **When do they go to the sports centre?**
- Check for specific times or days mentioned in the text.

3. **Who does he invite in the evenings?**
- See if any friends or family members are mentioned as being invited over.

4. **What kind of films does he like?**
- Look for adjectives or genres (e.g., action, comedy) that describe his film preferences.

5. **What do Jack and his friends do at the weekend?**
- Identify activities they engage in during the weekend, such as going out or having specific events.

Feel free to provide any specific information, and I can assist further!
