Correct sentence:

Road rollers squash the bumps, so the road becomes flat and smooth.

Why this is better (easy steps):

  1. Subject and verb: "Road rollers" means more than one machine, and "squash" matches (plural + verb) — that part was correct.
  2. Comma before "so": We put a comma before "so" because it shows the result of what happened (they squash the bumps, and as a result the road is flat).
  3. Use a word that shows change: Saying "becomes" or "make" shows the road changes to flat and smooth. You can also say: Road rollers squash bumps so the road is flat and smooth.

Other short options you can use:

  • Road rollers squash bumps so the road is flat and smooth.
  • Road rollers squash the bumps and make the road flat and smooth.

Try saying the corrected sentence out loud a few times — that helps you remember it!
