The correct answer is C. A book published in 1970 by a soldier trained to protect elephants

Explanation:

In the case of historical sources or sources that describe events in the past, a source is considered as credible usually when it is a primary source which means the source was written by someone that experienced or witness the event studied. Additionally, the author of the source needs to be an expert on the area or someone related to the event and the source should provide information about the event studied. This implies in the case of looking for information about early efforts to stop elephant poaching a historical source or a source written in the past would provide this information, but this also needs to be written by someone that is an expert or is related to the event and therefore, the source with credible information is "A book published in 1970 by a soldier trained to protect elephants" because this address the topic that is being studied but also is credible because it was written by someone that directly participated in the efforts to stop poaching.

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.
