Hi,
egmat please could you help me with the follwoing
As a result of record low temperatures, the water pipes on the third floor froze,
which caused the heads of the sprinkler system to burst, which released torrents of water into offices on the second floor.
Meaning: The temperature dropped to a record low and so the water pipes froze. As a result of this freezing the heads of the sprinkler system burst and thus a lot of water was released into the offices
Grammatical error: "which caused" cannot modify the preceding clause. We want to show the effect of the cause "the water pipes froze". So, a "comma + verb-ng" would be a good fit. But definitely "which caused" is incorrect. The same can also be stated for "which released".
Choices:-
(A)
which caused the heads of the sprinkler system to burst, which released torrents of water
Incorrect: As mentioned for the above reasons.
(B)
which caused the heads of the sprinkler system to burst
and which released torrents of water
Incorrect: "which caused" and "which released"
Doubt: The "and" before "which released" conveys that the result of the water pipes freezing is not only the burst of the sprinklers but also the release of water. But, isn't the "release of water" the effect of "the burst of the sprinklers"?
(C)
which caused the heads of the sprinkler system to burst,
torrents of water were then releasedIncorrect: Apart from the error of choice (A) this choice introduces a new error. It presents the later information in a distorted manner. This choice fails to connect the information "torrents of water..." with the rest of the sentence to show the effect of the pipes bursting
(D)
causing heads of sprinkler system to burst, then releasing torrents of water
Doubt: Please could you comment on this choice. Doesn't the "then releasing" convey the sequencing of events? first the pipes burst and then the water was released
(E)
causing heads of the sprinkler system to burst and release torrents of water
Here, "to burst" is parallel to "
(to) release" thus showing that the sprinkler system burst and the sprinkler system released water.
