Answer:
Based on Nick's observations, we can see that Gatsby is different from Buchanas because he is not a superficial person, but sensitive and intense. We can also say that Gatsby differs from Nick, because he is not a rational and obsessive person, but he acts on impulse and in the name of emotions.
Step-by-step explanation:
"The Great Gatsby" is a novel written by F. Scott Fitzgerald, where he shows the madness of the years in relation to the American dream and the greed for money.
The protagonist of these books, Gatsby, is portrayed by Nick, his friend, as someone who had "something gorgeous [...], some heightened sensitivity to the promises of life." with that, Nick showed that Gatsby was intense, emotional, promising and even poetic. This is very different from Nick, who is an observant and rational man, Gatsby, on the other hand, acts out of emotion in the pursuit of his goals, which is his biggest characteristic, the reason for his decadence.
Gatsby is also different from Buchanans who are shallow, listless and without the fire and emotion of Gatsby.
