This visualization test consists of a number of
items similar to the following
sample. A three-dimensional object is shown at
the left. This is followed by outlines of
five apertures or openings. First, you are to
imagine how the object looks from all
directions (rather than from a single direction
as shown). Then, pick from the five aper-
tures outlined, the opening through which the
object could pass directly if the proper
side were inserted first.
Here are the rules:
1. Prior to passing through the aperture, the
irregular solid object may be turned in
any direction. It may be started through the
aperture on a side not shown.
2. Once the object is started through the
aperture, it may not be twisted or turned.
It must pass completely through the opening.
The opening is always the exact
shape of the appropriate external outline of
the object.
3. Both objects and apertures are drawn to the
same scale. Thus it is possible for
an opening to be the correct shape but too
small for the object. In all cases,
however, differences are large enough to judge
by eye.
4. There are no irregularities in any hidden
portion of the object. However, if the
figure has symmetric indentations, the hidden
portion is symmetric with the part
shown.
5. For each object there is only one correct
aperture.

A flat pattern will be presented. This pattern
is to be folded into a three-dimen-
sional figure. The correct figure is one of the
four given at the right of the pattern. There
is only one correct figure in each set. The
outside of the pattern is what is seen at the
left.
