Mrs. Smith, a teacher, gave five students a make-up science test.  There were 
five questions on the test.  However, after grading the tests, she lost the 
answer sheet and her grade book.  She does know that someone got all five 
correct, someone got only four correct, someone got only three correct, 
somebody else got only two correct, and one person got only one answer 
right.  She doesn't know which student received which score.  Here are the 
test papers:
    Todd:     (1) eggs (2) evaporation    (3) alligator (4) potato   (5) teeth
    Sean:     (1) milk (2) transportation (3) alligator (4) kangaroo (5) teeth
    Samantha: (1) eggs (2) transportation (3) crocodile (4) kangaroo (5) ears
    Ryan:     (1) eggs (2) evaporation    (3) alligator (4) kangaroo (5) teeth
    Allison:  (1) milk (2) transportation (3) crocodile (4) kangaroo (5) ears
