Question

Which of the following farming techniques is essentially a version of terraced farming?

Answer 1

C because graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice. ( It basically means that terraced farming is farming over steps and using rain to wash away old soil so that's where the wet part comes in)
