Answer:
"The fire in the Mission District was subdued with water found blocks away in a hydrant."
Explanation:
Any sentence that have a problem-solution structure will be a technique in which both the problem/ issue of the situation and the solution for that very same issue will be given in the same line/ sentence. In such type of sentences, there are two sides of the issue juxtaposed with each other. One side will have an issue that may pose a threat or be a problem while the other will have the remedy for the problem.
In such cases, the availability of the solution is a must to give it a full 'problem-solution' sentence. Thus, from the given sentences, <u>the correct sentence that have this type of structure is the second option</u>. In this sentence, the sentence not only talks of the problem of the "<em>fire</em>", but also the solution for this fire which is found in the "<em>water... found blocks away in a hydrant</em>".
