Which passage is the best example of deductive reasoning

D is using deductive reasoning,

Explanation: deductive reasoning is when you figure something out using logic and using the information you already have, without asking someone.

The answer is letter D

Explanation:

   Deductive reasoning means having  true statements (also called premises) and reaching to a logical conclusions based on them. There is always a logical thought process, where you move from general ideas to more specific ones.

   Let's have a look at this example of deductive reasoning:

All apples are fruits. Pink Lady is a type of apple. Therefore, the Pink Lady is a fruit.

The first two sentences are the premises. From those two true statements, the logical conclusion that the Pink Lady apple is a fruit is reached.

   In the question, sentence D is an example of deductive reasoning. The first two statements are the true facts that we have (Everyone got an A in Mr. Kims's class and Casey is in that class). Therefore,  Casey is getting an A. There's no room for another conclusion.  You have reached a conclusion based on true statements.

in this passage from chapter 6 of "animal farm", by george orwell, what the author is ridiculing in this passage is the frivolity of some rules.

clover, the mare, believes she remembers that the fourth commandment forbade sleeping in beds because it was something that humans did. snowball, napoleon, and the pigs are brain-workers who look after the welfare of the farm. they are the obvious leaders because they are smart, and so they are entitled to eat the best food and sleep in beds. it is squealer, who says these lines making the difference between sleeping with sheets, what humans do, and sleeping in beds, what pigs do. the unwillingness to question authority makes the oppressed to obey without thinking.
