A teacher gave her students a short quiz, but after grading the test, she lost her grade book and the answer key. Here are five students' exams:

Paul's test:

1. eggs
2. evaporation
3. Alligator
4. a potato
5. teeth

Todd's test:

1. milk
2. transportation
3. Alligator
4. a kangaroo
5. teeth

Jason's test:

1. eggs
2. transportation
3. Crocodile
4. a kangaroo
5. ears

Alicia's test:

1. eggs
2. evaporation
3. Alligator
4. a kangaroo
5. teeth

Bebe's test:

1. milk
2. transportation
3. Crocodile
4. a kangaroo
5. ears

She did remember, however, that someone got all five questions correct, someone got four right, someone got three correct, another person got two questions correct, and one person got only one answer right.

Who got all five questions correct?

Q. Who got all five questions correct?
A. Alicia

Since the only information that we have (other than the answers to the quiz) was the number of questions each person got right, one could solve this by using IF/THEN. We do know that there are 5 students and that someone got all five questions correct, someone got four right, someone got three correct, another person got two questions correct, and one person got only one answer right.

If one person got all 5 questions correct then we can let each person have all of the questions correct until we get the correct combination.

The students and their correct answers are as follows:
Paul-4, Todd-3, Jason-2, Alicia-5, Bebe-1
