The correct way to write sentences 21 and 22 is:

**d** if there is a shocking cave like this 980 feet below the surface of mexico, then there could be more discoveries just like it in other parts of the world.

This option uses a comma before "then," which correctly sets off the conditional clause from the main clause. Additionally, "Mexico" should be capitalized. So, a corrected version of option d would be:

**If there is a shocking cave like this 980 feet below the surface of Mexico, then there could be more discoveries just like it in other parts of the world.**
