Question

I would rather play chess than backgammon because it is more challenging correct or incorrect.

2. I enjoy jogging every day because in this way I get regular exercise Correct or Incorrect.

Answer 1

Both sentences can be deemed as "correct"

Chess is more challenging because it involves absolutely zero luck and is all about skills, while backgammon features far less possible options for a game. The other sentence features jogging everyday as an exercise and it is indeed regular exercise if done every day.
