Answers will vary. Here are some examples of what may not have been clear from the given descriptions. In Description 1, it is not clear what is meant by "looks like a bird." Also, the description doesn't tell you how to place each shape in relation to the others. In Description 2, the hexagon could be oriented in different ways (top and bottom sides horizontal or left and right sides horizontal). It is also not clear how to attach the triangles and squares to the hexagon or the two triangles to the square. Description 3 removes these ambiguities.
