(b) 61 // ((-8 + 2) * 4) ** 2
(c) 61 // (-8 + 2 * 4) ** 2
(d) 61 // ((-8 + 2) * 4) * 2

Question 3

What is the value of x after the execution of the code below completes?

(a) 5
(b) 4
(c) 3
(d) 2

x = 0
a = 0
b = -5
if a > 0:
    if b < 0: 
        x = x + 5 
    elif a > 5:
        x = x + 4
    else:
        x = x + 3
else:
    x = x + 2
print(x)

Question 6

What is the value of x after the execution of the code below completes?

(a) 5
(b) 4
(c) 3
(d) 2

x = 0
a = 5
b = 5
if a > 0:
    if b < 0: 
        x = x + 5 
    elif a > 5:
        x = x + 4
    else:
        x = x + 3
else:
    x = x + 2
print(x)
