LR Question 25 Explanation

QUESTION TEXT: Salesperson: If your vacuuming needs are limited to cleaning…

QUESTION TYPE: Strengthen

CONCLUSION: An inexpensive handheld vacuum is likely sufficient if you are only cleaning small areas of uncarpeted floors.

REASONING: Inexpensive handheld vacuums are easy to use and good for wood and tile floors.

ANALYSIS: The salesperson says that as long as you don’t have carpet and you’re cleaning small areas, the inexpensive handheld vacuum should be good. We also know that these vacuums are good for wood and tile floors.

But what about other kinds of floors? We only know that the vacuum is good for wood and tile. This isn’t the same as “uncarpeted”.

Note that “easy to use” here is a red herring. You should be zeroing in on the flaw above.

___________

1. CORRECT. If these are the only floors most people will need to vacuum, then any “uncarpeted floor” is probably wood or tile. This would mean that the vacuum is likely sufficient for the customer’s needs.
2. The salesperson isn’t trying to convince you that the vacuum is good for carpet. This doesn’t support the conclusion.
3. The argument isn’t concluding that some vacuums will be inexpensive. The conclusion is instead that inexpensive handheld vacuums will be sufficient for the job.
4. The conclusion isn’t that you need a vacuum cleaner. It’s that a specific vacuum type will meet your needs.
5. The salesperson isn’t arguing that some vacuums are more expensive. This doesn’t support the conclusion.
