Question

1. match the statements with the types of stars.

the hot remains of a star that has exhausted its fuel can be similar in size to earth yet 200,000 times more massive.
most of the stars—including the sun—in the milky way are this type of stars which fuse hydrogen into helium.
a star has fused all of its hydrogen into hellum and its brightness increases up to 1,000 times or more.
older stars have expanded to hundreds of times their original size.

supergiants
white dwarfs
red giants
main-sequence

Explanation:

1. For "The hot remains of a star that has exhausted its fuel can be similar in size to Earth yet 200,000 times more massive" → white dwarfs (remnants of stars, Earth - sized but massive).
2. For "Most of the stars—including the sun—in the Milky Way are this type of stars which fuse hydrogen into helium" → main - sequence (main - sequence stars, like the Sun, fuse H to He).
3. For "A star has fused all of its hydrogen into helium and its brightness increases up to 1,000 times or more" → red giants (after H fusion, expand and brighten).
4. For "Older stars have expanded to hundreds of times their original size" → supergiants (very large, older evolved stars).

Answer:

• "The hot remains of a star that has exhausted its fuel can be similar in size to Earth yet 200,000 times more massive" - white dwarfs
• "Most of the stars—including the sun—in the Milky Way are this type of stars which fuse hydrogen into helium" - main - sequence
• "A star has fused all of its hydrogen into helium and its brightness increases up to 1,000 times or more" - red giants
• "Older stars have expanded to hundreds of times their original size" - supergiants
