what are the limitations of having nick serve as the narrator of this story? How does chapter 2 make this limitation obvious?

The limitations of having Nick as a narrator is that the readers are not able to know the thoughts of other characters. In First-person narrative, readers get to know only what narrator knows and what he sees and perceives about the event.

The evidence of this limitation in chapter is apparent when Nick gets drunk and he himself claims that his drunkness has a  dim hazy cast over it.

Explanation:

The Great Gatsby is a novel written by F. Scott Fitzgerald. The novel is about Jay Gatsby and is narrated by Nick Carraway.

The story is narrated from First-person point of view. The limitation of having Nick as a narrator is that readers are not able to perceive the thoughts of other characters, especially that of Jay Gatsby. The readers get to know only what limited view of Nick narrated to them. They are able to see only what Nick sees and nothing beyond it or other's viewpoint. It is the viewpoint of Nick that moulds the story of Gatsby.

This limitation is apparent in Chapter 2 of the novel when Nick gets drunk at the party and himself admits that his drunkness has a  dim hazy cast over it. This suggests that Nick was not able to trust his own narration of this particular event after he got intoxicated.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
