@Kevin_Lin Thank you!

@Kevin_Lin In your opinion, would it be faster and more efficient to highlight sufficient and necessary clauses rather than writing them down?

@LaneyWilliams Yea but the word "cannot" is included in group 4, if you look in the beginning of the page. Cannot and Can't are the same. I was confused as well. Thank you for asking the question @AliMerhi

Please help @Kevin_Lin
