```Answers to the quiz, from two perspectives:
A is  http://www.coginst.uwf.edu/users/phayes/simpledatatype.html
B is  http://www.coginst.uwf.edu/users/phayes/simpledatatype1.html

1.
xxx ppp "zzz" .

A. "zzz" denotes 'zzz'; ppp value of xxx is 'zzz'
B. value is undetermined.

2.
ppp rdfs:drange ddd .
xxx ppp "zzz" .

A. same as above; the drange is irrelevant.
B. value is ddd("zzz")

3.
ppp rdfs:drange ddd .
xxx ppp _:1 .

A,B: ppp value of xxx is undetermined

4.
ppp rdfs:range ddd .
xxx ppp _:1 .
_:1 rdfs:dlex "zzz" .

A, B: value is undetermined

(Unless, that is, we also know that rdfs:range rdfs:subPropertyOf rdfs:drange.)

5.
ppp rdfs:drange ddd .
xxx ppp _:1 .
_:1 rdfs:dlex "zzz" .

A,B: value is ddd("zzz"), ie the datatype value

6.
xxx ppp _:1 .
_:1 ddd "zzz" .

A, B: same as above

7.
xxx ppp _:1 .
_:1 ddd "zzz" .
ppp rdfs:drange eee .

A, B: same as above. Notice this is not a datatype clash because dlex
is not used.

8.
xxx ppp _:1 .
_:1 rdfs:dlex "zzz" .
ppp rdfs:drange eee .

A, B: value is eee("zzz"), ie the range datatype is used to fix the
dlex interpretation.
