Which of these sentence segments does not contain a capitalization error? on july 20, 1969, neil armstrong landed the lunar spacecraft, the eagle, on the moon.

The sentence should read as follows;

On July 20, 1969, Neil Armstrong landed the lunar spacecraft, The Eagle, on the moon.

So it wouldn't be the first one because July should be capitalized, proper because it's naming a particular month.

It wouldn't be the second because Neil Armstrong should be capitalized, proper because it's naming a particular man.

It wouldn't be the third because The Eagle should be capitalized, proper because it's naming the spacecraft.

So the answer is the fourth option

on the moon

Hope this helps. :)

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

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.
