In Browning's poem, "My Last Duchess," the Duke was married to his lovely wife, the Duchess, whose painting he has on the wall of his castle and is showing it to a visitor. As we read the poem, we find out that the Duchess liked to flirt a lot with other men which is why the Duke had her killed. I'm not sure who Browning seems to sympathize with - I guess <u>the Duchess</u>, given that she was murdered. The Duke is not the one who should be sympathized with.
People use logical fallacies because they don't know how to effectively prove their point. For example, politicians may try to attack their opponent's reputation instead of mentioning something that is actually relevant to the topic.
I believe that the best answer for this question would be sanguine. People who fall under the category of the sanguine temperament tend to be lively, pleasure-seeking, talkative, and highly social. They can easily fall in love and may be flighty and forgetful. You can also reach this conclusion by ruling out the others; choleric individuals are angry and impulsive, melancholic individuals are introverted and solemn, and phlegmatic individuals are thoughtful and calm. Hope this helps.
What detail? I don’t see one.
