Brent was hired.
Since the person hired needs to have more requirements than the others,
he needs to have 3 or 4 of the 4 requirements. And according to
the 1st fact no one has the same pair of requirements as another so the
one who was hired could not have all four requirements.
Craig has experience and is a veteran. To be hired he needs a 3rd
requirment. If craig also had High School, then he'd have the
same pair of requirements as Brent who has High School and is a
veteran, and that violates 1). If Craig also had references then
he'd have the same as David and that violates 1). Therefore Craig
is not the one who was hired.
With the same type of reasoning, Alden also is not the one who was hired.
David cannot be a vetern but he could have high school which would give
him enough to be hired. But Brent, who cannot have experience
could have references so he too could be the one who was hired.
But if we look back at 1) we need to make sure all six pairs of
requirements are met. With the above solutions for Brent and
David, one pair is not met. The only person who fill in the blank
for us is Alden by having one more requirement. If David is
hired, then the left over pair is veteran and References but Alden
cannot satisfy that unless he gets two more requirements since he only
has High School. But if Brent is hired, then the left over pair
is High School and 2 yrs experience, which Alden can fulfill by also
having experience.
So everyone was the requirements mentioned in the question but Alden
also has experience and Brent also has Satisfactory references and
therefore Brent is the one who gets hired.
