I should warn people that for some of Puzzles 150-153, the answer is "there are no such adjoints". But don't be scared: this answer will arise as you use the definition of adjoint to figure out what the desired adjoint is like!

You can almost always work out the adjoints of a functor, or the lack of adjoints, by patiently using the definition of adjoint functors.
