## Best answers for each gap:
1. **b) fitted** - "Suited" suggests a general sense of appropriateness, while "fitted" implies the technology is integrated into the home itself.
2. **d) digital** - "Sensitive" doesn't quite fit the context of apps and devices, while "digital" accurately describes their nature.
3. **c) cosy** - "Convenient" describes the practicality, but "cosy" emphasizes the feeling of comfort and ease a smart home provides.
4. **b) residents** - "Homeowners" makes the most sense given the context of the text. While "scientists" is incorrect, "locals" or "citizens" wouldn't fit either.
5. **b) lighting** - "Internet" is too broad for this specific instance, while "lighting" is a key example of a system controlled by smart home technology.
6. **d) unlock** - "Close" suggests the opposite action, making "unlock" the correct choice.
7. **c) programmes** - "Meditation" doesn't match the context of appliances, while "programmes" refers to scheduling functions for devices.
8. **b) appliances** - "Mediation" isn't relevant, while "appliances" specifically refers to the devices being controlled.
9. **c) rely on** - "Seen" doesn't convey the correct meaning, while "rely on" indicates dependence on the smart refrigerator's features.
10. **c) security** - "Efficiency" suggests a different aspect of smart home systems, while "security" accurately reflects their protective function.
