If a wig has any handmade components, it is more expensive than one with none. ██████████ █ ███████████████ ███ ██████ ████ █████████████ ██ ██████████ ████████ ███████████ ███ █████ █████ ██ ████ ████ ██ ███ ███ █████ █████ ████████████ ███ ███ ████ ████████ █████ ████ ██████ ██ ████████████ ██ ███ ███████████████ ████ ██████ ██ ████████████

Summary

The author concludes that all made-to-measure wigs should be dry-cleaned.

This is based on the following:

Made-to-measure wigs range from medium-priced to expensive.

If a wig has a handmade foundation, then it uses human hair. (”Hand made foundations are never found on wigs that don’t use human hair.”)

Wigs that contain human hair should be dry-cleaned.

Missing Connection

The last two premises, together, establish that if a wig has a handmade foundation, then it should be dry-cleaned. So if we want to conclude that made-to-measure wigs should be dry-cleaned, we want to show that made-to-measure wigs have a handmade foundation. How can we do that?

Well, the first premise tells us that made-to-measure wigs range from medium-priced to expensive. If we can show that “medium-priced to expensive” implies “handmade foundation,” that will show that made-to-measure wigs have a handmade foundation, which in turn will show that they should be dry-cleaned.

The conclusion of the argument ███████ █████████ ██ █████ ███ ██ ███ █████████ ██ ████████

Any wig whose █████ █████ ██ ███ █████████████ ██ █████████ █████ ███ █ ████████ ███████████

Since we know made-to-measure wigs are in the medium-priced to expensive range, (A) establishes that these wigs have a handmade foundation. Combine that with the last two premises, and we can conclude that made-to-measure wigs should be dry-cleaned.

If a wig's ██████████ ██ █████████ ████ ██ ██ ████ █████████ ████ ███ █████ ██████████ ██ ███ █████████

(B) doesn’t establish anything about made-to-measure wigs or wigs that are medium-priced to expensive. So we’d still have no way to conclude that made-to-measure wigs should be dry-cleaned.

A wig that ███ ███ ████████ ██████████ ██████ ██ ████████████

(C) doesn’t establish anything about made-to-measure wigs or wigs that are medium-priced to expensive. So we’d still have no way to conclude that made-to-measure wigs should be dry-cleaned.

If a wig's ██████████ ██ █████████ ████ ███ █████ ██ ██ █████ ██ ███ ██████ ██████

(D) doesn’t establish anything about made-to-measure wigs or wigs that are medium-priced to expensive. So we’d still have no way to conclude that made-to-measure wigs should be dry-cleaned. Although (D) shows that wigs with handmade foundations are at least medium-priced, this doesn’t imply that wigs that are medium-priced to expensive must have a handmade foundation.

Any wig that ██████ ██ ███████████ ███ █ ██████████ ████ ██ █████████

We want to conclude that made-to-measure wigs should be dry cleaned. An answer that tells us what is true IF a wig should be dry-cleaned doesn’t establish that certain wigs should be dry-cleaned.
