Reading for main ideas, and not details, a. decreases your reading speed c. both of these b. increases your reading speed d. none of these

b. Increases your reading speed.

Explanation:

When you read a text, and you only focus on the main ideas, you are able to increase your reading speed. This is because as you read, you are able to ignore those elements that are not important enough and instead focus on important ones that really affect the plot. Many details are overlooked, helping you finish a page faster. This is a good strategy to use when you have little time and a lot of information to read.

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.

the first, third, and last sentences are correct for plato.
