Points to realize:
1.
 There may be exceptions to any item on the list, for instance a particular
 clock may share the properties of the 'with' list of problem two, BUT MOST
 ORDINARY clocks do not.  All the properties apply the vast majority of the
 the items mentioned.  Extraordinary exceptions should be ignored.

2.
 Pay the most attention to the 'with' list.  The 'without' list is only
 present to eliminate various 'stupid' answers.
