Here are the suggested options for the blanks in the passage:

17. **A. destroying** - "a destruction" doesn’t fit the context and “destroyer” is incorrect. "Destructive" also doesn’t fit here.

18. **B. staying** - “remaining” is the most appropriate choice.

19. **A. Unless** - This fits the sentence structure that suggests the condition under which something happens.

20. **C. agriculture** - This is the best fit for the context of using land.

21. **C. under** - It suggests that the forest must be rich in nutrients.

22. **C. unfortunate** - This implies that it’s unfortunate that people believe that land is rich when it’s not.

Now for the TRUE or FALSE statements:

23. **TRUE** - The passage is about a kind of energy.
24. **TRUE** - Electricity has many uses.
25. **FALSE** - The passage implies that life would be affected without electricity.
26. **TRUE** - The list of appliances dependent on electricity is endless.
