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, the correct sentence that have this type of structure is the second option. In this sentence, the sentence not only talks of the problem of the "fire", but also the solution for this fire which is found in the "water... found blocks away in a hydrant".

can you give us the passage> ?

explanation:

given the fact that the question is about the detail that best support the idea that oppressive leaders use   propaganda to achieve thir goals,   the first option does not refer to any kind of propaganda, since it only tells about that the milk and the windfall apple should be reserved for the pigs. in the second option, that is, "snowball and napoleon sent out flights of pigeons whose instructions were to mingle with the animals on the neighbouring farms, tell them the story of the rebellion, and teach them the tune of "beasts of england". it can be identified that the oppressors make use of the propaganda, which is represented by the pigeons, and the information they have to tell other animals about what was happening in the farm in order to get their objectives. for that reason, the right answer is the second option, taking into account that the third option do not refer to propaganda since it only talks about that they did not want jones back. and, finally, the last option refers to the result of the given news, but it does not mean about the propaganda they used to achieve their goals.
