## Assembly

*In this test you are to figure out how something would look if it were put together properly. The parts to be put together are shown at the beginning of each problem and are followed by five pictures showing five different ways the parts could be put together. Only one of them is correct.
Each part is marked with one or more letters, each of which stands for a place on the part. Letters referring to places that do not show are placed outside the part, with a dotted line pointing to the underneath side, or the place that you can't see.
*

*In deciding how the parts should be put together, do not think about what the completed thing is or does. Just follow the letters on the parts that show you how they are to be put together.*
