Question

Which of the roles filled by the president do you think is the most important? Explain your reasoning behind making this decision.

Answer 1

The role of the president "to lead the country" is very important. 
Without a leader, we would be divided, and "united we stand, divided we fall"

its a simple as that, without a leader, we would be a lot more divided than we are now and without the president, well, there might be chaos
