This includes replacing broken windows, repairing disconnected electrical fixtures, emergency plumbing repairs, etc.
- AOnly (i)
- BOnly (ii)
- CBoth (i) and (ii)
- DNeither (i) nor (ii)Correct
Solution
Concept
Preventive and corrective building maintenance definitions
Formula
NONE
Step-by-step solution
1. Preventive maintenance aims to prevent damage, while corrective maintenance restores functionality. 2. Since both statements are correct definitions, neither statement is false. Answer: D
Explanation
Preventive maintenance involves proactive tasks like clearing gutters and inspecting components to prevent structural damage. Corrective maintenance includes reactive repairs like replacing broken windows or fixing electrical faults after damage has occurred. Because both statements accurately define these maintenance types, neither statement is false, making option D correct.
Why the other options are wrong
A) Statement (i) accurately describes preventive maintenance and is therefore true. B) Statement (ii) accurately describes corrective maintenance and is therefore true. C) Both statements are true, so neither statement is false.
Shortcut
Preventive avoids future damage; Corrective fixes existing failures (both statements are TRUE).
Common mistake
Misinterpreting the negative prompt ("is/are false") and selecting option C under the assumption that both provided definitions are incorrect.
Correct answer: D) Neither (i) nor (ii)
