Answer 2

Answer with Explanation:

Elliptical galaxy = Forms a perfect sphere or an ellipse and is flattened to some degree.

• The context clue here is the word "ellipse." The elliptical galaxy follows the elliptical shape. It is considered as the most abundant type of galaxy.

Galaxy = Is a collection of several billion stars and interstellar matter isolated in space.

• A galaxy is made up of billions of stars, and these stars are drawn together by gravitational force.

Lens galaxy = Has a large flattened core.

• A lens galaxy has a large flattened core, similar to the shape of a lens.

Spiral galaxy = Has a central core from which curved arms spiral outward.

• The context clue here is the word "spiral outward." The swirling arms is a common characteristic of spiral galaxies.
