Critical Reasoning

Workshop instructor: Sewing leather is, in many respects, simpler than sewing fabric. For instance, pieces of fabric must be sewn together so that the "bias," the direction in which the fabric stretches most, matches throughout the final product; this consideration is irrelevant for leather. Furthermore, if fabric is not pressed before it is sewn, the final product is liable to "pucker" or to lie unevenly; leather, on the other hand, does not need to be pressed. Nevertheless, it is inadvisable for novice sewers to begin sewing leather until they have mastered the basic skills of sewing using fabric.

Which of the following, if true, most strongly supports the instructor's contention?

A) To be used for sewing leather, most sewing machines must be fitted with a new attachment, which is inexpensive but usually must be purchased separately.

B) Many garments that can be sewn with fabric cannot, for either practical or aesthetic reasons, be sewn with leather.

C) Fabric is available in a much larger variety of weights, colors, and textures than is leather.

D) When stitches are removed, as in the case of errors, they leave permanent, visible perforations in leather but not in fabric.

E) While leather can be stitched in any direction, fabric must be stitched in particular directions to prevent undesirable stretching or wrinkling of the final product.
