# 318 logic/attribute.p

All the items in the first list share a particular attribute. The second
list is of some items lacking the attribute.

Set#1
with: battery, key, yeast, bookmark
w/out: stapler, match, Rubik's cube, pill bottle

Set#2
with: Rubik's cube, chess set, electrical wiring, compass needle
w/out: clock, rope, tic-tac-toe, pencil sharpener

Set#3:
with: koosh, small intestine, Yorkshire Terrier, Christmas Tree
w/out: toothbrush, oak chair, soccer ball, icicle

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.

logic/attribute.s

The attribute puzzle format is a traditional format in math education.
It occurs in logic materials developed in the sixties by EDC in Boston,
with visual objects. Example:

these are gloops: A B C D E
these are not gloops: F G J L N
which of these are gloops? O P Q R S
