Answer choices

  1. Unsupported Trigger2% picked this

    If a fabric is not a heavy tapestry fabric, then it is not appropriate for

    The first sentence gives us a conditional that says, If a fabric is a heavy tapestry, then only appropriate for stuff that's infrequently laundered. We weren't given any rule for what's true if a fabric is not a heavy tapestry, so there's no way we can derive an outcome about that.

  2. Bad Trigger Match3% picked this

    Heavy tapestry fabrics should not be used unless swags or balloon valances

    We have a rule that says, needs to be heavy tapestry laundered frequently → fabrics should not be used This answer is saying it's not swags and heavy tapestry not balloon valances → fabrics should not be used Can we say that, "If it's not a swag or a balloon valance, then it needs to be laundered frequently"? No, we can't say that. There might be other things besides swags and balloon valances that don't need to be laundered frequently. To put this another way, the paragraph has communicated to us that it's conceivably appropriate to use heavy tapestry fabrics if you're making swags or balloon valances. But they never told us that those are the only two cases in which heavy tapestry fabrics would be okay, and the answer is saying these are the only two cases.

  3. Unsupported Outcome5% picked this

    If heavy tapestry fabrics are appropriate for a particular application, then that application must be

    The first sentence gives us a conditional that says, If a heavy tapestry fabric is appropriate, then doesn't need to be frequently laundered. In order for this answer to be derivable, we'd need to think that, "If it doesn't need to be frequently laundered, then it must be a window treatment". Is that something we know? No, just like (B) this is too strong. We were told that window treatments don't need to be frequently laundered, but this answer is acting like window treatments are the only thing that doesn't need to be frequently laundered.

    Why this is right

    This is what we were predicting, although it's certainly worded in the weirdest way they could think of. We wanted "heavy tapestry is not appropriate for clothing (such as skirts or jackets). By contrapositive, this is saying Fabric is heavy → not appropriate for tapestry skirt or jacket We know from the first sentence that Fabric is heavy → not appropriate for tapestry stuff that needs to be laundered frequently Can we say that skirts and jackets need to be laundered frequently? Yes, we were told that no type of clothing belongs to the category of "doesn't need to be laundered frequently", which means that all types of clothing belong to the category of "does need to be laundered frequently". Again, we were able to build this chain: Clothing does need heavy (such as skirt → frequent → tapestry not or jacket) laundering appropriate By contrapositive, heavy does not not clothing tapestry is → need freq. → (such as skirt appropriate laundering or jacket)

    Skill tested: Most Supported · how this choice captures the argument's function is the move to repeat next time.

  5. Contradicted3% picked this

    Heavy tapestry fabrics are sometimes appropriate for use in types of clothing other than

    Since all clothing needs to be laundered frequently, heavy tapestry fabrics would be inappropriate for all clothing.
