The tension around me every day made things really tough. It was bad enough that my dad was so far away for so long. But while he was off in the jungles of Vietnam fighting for some elusive principles, people at home were angry and unsupportive. I wanted to be proud of my dad, but I couldn't understand what he was fighting for. Or against. If I could just grab ahold of that shadow, maybe could see things from his perspective. But it always slipped away.

right angles are formed by perpendicular lines. if the lines would extend, to make two intersecting lines, they would form four right angles.

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.

i need some details.
