Logic Problem Solution:
Empty Nest
By clue 3, Tara isn't the Robbins child who is in graduate school;
nor is Kristin (7) or Ian (10). Either Brad or Jennifer is studying
for a master's degree. Since neither Jennifer (1) nor Brad (5) is
at Ocean City A.& M., in clue 7, Kristin can only be a junior at most.
Similarly, since neither Jennifer (1) nor Brad (5) is majoring in
computer science, in clue 10, Ian also can only be at most a junior.
By clue 3, Tara also can be at most a junior. Therefore, the other
of Jennifer and Brad who isn't in grad school must be a senior. Since
neither Jennifer (1) nor Brad (5) is at Ocean City A. & M., in clue 7,
Kristin must be a sophomore or freshman. By clue 11, she is a college
sophomore. Similarly, since neither Jennifer (1) nor Brad (5) is a
computer science major, Ian is then a freshman (10). By elimination,
Tara is a junior. Since the student at Maryland State isn't a senior
(9), by clue 3, the Maryland State student is in graduate school and
the one studying drama is a senior. By clues 1, 5, and 7, Tara attends
Ocean City A. & M. Neither Jennifer (12) nor Brad (14) is a student at
Winterhaven University, so either Kristin or Ian is. If Kristin were
at Winterhaven, by clue 2, the senior would be at Summerset Tech and
Tara would be a math major. Ian would be starting Emily Dickinson
College and wouldn't be a business major (13), nor is he a physics
major (4). Ian would be studying computer science--no (10). So, Ian
rather than Kristin is starting at Winterhaven University. He isn't
majoring in mathematics (8); so, by clue 2, Tara is the math major
and the drama senior attends Summerset Tech. By elimination, Kristin
is a student at Emily Dickinson College. By clues 1, 5, and 10,
Kristin is taking computer science courses. Ian is a business major
(4), and the grad student is preparing for a master's in physics. The
latter is Brad (6); Jennifer is the drama major. In sum, the Robbins
children have given their parents "empty nest" syndrome as follows:
- Master's - Brad in physics at Maryland State
- Senior - Jennifer in drama at Summerset Tech
- Junior - Tara in mathematics at Ocean City A. & M.
- Sophomore - Kristin in computer science at Emily Dickinson
College
- Freshman - Ian in business at Winterhaven University
