Main Connectives Again: Choose the main connective for each formula.

Identify the main connective of each formula. Remember, a tilde can be the main connective only when it's the only connective completely outside parentheses. This can only happen when the tilde is the first connective in the string of symbols.This exercise should be relatively easy, but main connectives are extremely important, and you want to get to the point where you can identify them with ease.
