Answer:
The program in Python is as follows:
firstName = []
lastName = []
while True:
fName = input("First Name: ")
lName = input("Last Name: (Enter to quit): ")
if not lName:
break
firstName.append(fName)
lastName.append(lName)
for i in range(len(firstName)):
print(firstName[i] . lower()+"."+lastName[i] . lower()+" mycollege . edu")

Answer:
a=4 , b=1
Explanation:
I'm not a computer science major at all but I think I can help you with this code.
Our program wants us to add 2 to a get new a value while also subtracting 1 from b value to obtain new b value. We we want to for for as long b is not 0 and a/b is nonnegative.
One round we get:
New a=0+2=2
New b=3-1=2
Let's see if we can go another round:
New a=2+2=4
New b=2-1=1
We can't go another round because b would be negative while a is positive which would make a/b negative. So our loop stops at this 2nd round.
a=4 , b=1
Other notes:
2nd choice makes no sense because a is always going to increase because of the addition on a and b was going to decrease because of the subtraction on it.
Third choice makes no sense because a/b doesn't even exist.
Fourth choice a/b is negative not nonnegative.
