Answer:
Comparing
Explanation:
You see similar means to things are alike
Example: Scrunchies are similar to hair ties because they both hold up your hair
Alike means the same as similar. Alike is a synonym for similar.
Also could mean you are including two alike or similar things.
Example: wearing prescription eye contacts is also like wearing prescription eyeglasses because they both help you to see
( now both eye contacts and glasses are different because one is put directly on your eye but they are similar because they can both help you see)
(I hope this helps answer your question!)
