Answer C: B-C-D-A
Completed textA plumber found a cracked washer in the tap. Before fitting the new washer, she turned off the water. With the supply off, she replaced the cracked washer. As a result of this replacement, the leak stopped.
- Not correct. The new washer in C assumes the replacement context that B has not introduced in this text.
- Not correct. C says the water was turned off before fitting, but this order places that step after replacement.
- Correct. B identifies the faulty washer; C turns off the water; D replaces it with the supply off; A gives the result.
- Not correct. A describes the result of this replacement before D performs it.
