For the next four numbers, you will
see fictitious constellations of
stars. Some stars are light; others
are dark. All stars are the same
size.

So, when some stars appear to be
large, they are in the foreground
of the constellation; when others
appear to be small, they are in
the background.

Note that further stars might be

hidden behind those that you see.

Look at the example below.

eo LEFT = ee
o

® FRONT

The perspective from which you see
the constellation on the left is
assumed to be the view from the
FRONT. If the constellation
would rotate in space or if you
were in a spaceship orbiting it,
you could see it from other
perspectives, relative to the front
view. For instance, you might see
it from the LEFT or from the

only has one of each type so you ask the children their preferences. You decide to give
each child one of their preferred toys.Which animal will you give Jezebel?

TOY PREFERENCES:

The trick here is to realize that you can ignore the children with
more than four choices.

Josh, Jamelia and Jasbeet all have only two or three choices
and all want a panda, donkey or dog, so they must each get
‘one of these.

Jezebel also wants a panda, donkey or dog, but she would
also accept a kitten, so she must be given this, if each child is
