Answer 1

Answer:

A. close one eye while looking at the moon

Explanation:

Moon illusion is a term that describes the optical illusion of the observer, in which, the moon appears huge or larger to the observer. In other words, moon illusion makes moon appears bigger from observers view than it actually is, in the sky.

However, to solve the moon illusion, one will have to close one eye while looking at the moon through a narrow pipe.

The other ways to make the moon illusion disappear is to view the moon from a narrow view or pipe such that the foreground terrain disappears. This can be done, by viewing or observing Moon through a narrow pipe or in between two fingers.

Answer 2

Answer:

The answer to the question is option "a" "which is  close one eye while looking at the moon."

Explanation:

Ibn Alhazan proposed this explanation for the moon illusion around 1000 CE. He opined that when one looks at the moon near the horizon through a hole in a piece of paper held some distance in front of the eye, the moon appears smaller. The "horizon effect" largely disappears. Al-Haytham suggested that when the moon is overhead, we perceive it to be closer and therefore smaller. But when the moon is rising over a distant horizon, we perceive it to be farther away and therefore larger. ... The Ebbinghaus illusion is one optical effect that might help explain the moon illusion.

Moreover, the Moon illusion is an optical illusion which causes the Moon to appear larger near the horizon than it does higher up in the sky. It has been known since ancient times and recorded by various cultures. The explanation of this illusion is still debated.
