Question

1. choose the best answer.

an area of strong gravity from which light cannot escape, formed by a collapsed supernova, is a
\tsupernova
\tred supergiant
\tnebula
\tblack hole

1. choose the best answer.

clouds of dust and gas form a ______.
\tred supergiant
\tsupernova
\tnebula
\tblack hole

Explanation:

Question 11

To solve this, we recall astronomical concepts: A black hole is a region with extremely strong gravity where light can't escape, formed from a collapsed supernova. A supernova is an explosion, a red supergiant is a star stage, and a nebula is a gas/dust cloud (not related to light escape from collapsed supernova).

In astronomy, clouds of dust and gas in space form a nebula. A red supergiant is a star, a supernova is an explosion, and a black hole is a gravity - dominated region (not formed by just dust and gas clouds).

Answer:

black hole (the option corresponding to "black hole" among the choices for question 11)
