The correct answer is A. Evil
Explanation
In the Don Quixote fragment, he refers to "Friston" a character he blames for having "who carried out my study and books" and "turned these giants into mills" to rob him of the glory of vanquishing them. Later, he expresses that their relationship is one of "enmity" because Frinton has acted against Don Quixote, according to above it can be inferred that the word enmity according to the context described refers to the evil act of Friston against Don Quixote, so the correct respect is A. Evil.
It is false that almost everyone agrees that the first English novel was Don Quixote. Don Quixote is a Spanish novel, written by Miguel de Cervantes, and it is considered to be the first modern novel, but not an English one.
A good way to intensify meaning in the conclusion of a speech is to use an example.
Giving the audience an example helps the audience remember the importance of what you are saying and can help intensify the meaning. While a long story might capture the audience's attention, it would be something that would serve better in another part of the speech. A conclusion should not include any new information and should simply summarize what you have already said. It may also call your audience to action.
