Question 3 Write an expression that is true exactly when a is less than b and c is equal to d. Assume that these four variables already exist (so all you are providing is an expression that I could type at the >>> shell prompt). Question 4 Here is an interaction at the shell: >>> a = False >>>> b = False >>> a and b or True True Explain why the value of the expression at the bottom is True. How would you add parentheses to force the expression to evaluate to False? Question 5 Using a Boolean operator, rewrite this if-statement so that it takes fewer lines of code. if x 5: print("hi")
