#25 - Salesperson: If your vacuuming needs are limited to

[csafe]

Hello. I am a bit confused with this one and think I have the correct thinking pattern after reviewing the previous responses in this thread. I am going to explain how I think about the correct answer choice in my head and please let me know if this way of thinking is correct.

Because the salesperson jumps from 'uncarpeted' to 'wood and tile' they assume that the only flooring that uncarpeted is wood and tile. the answer choice also included carpet, which confused me. But, I believe what the author is saying that if the floor is not uncarpeted, then it has to be carpeted? thus, the only flooring options is wood, tile, and carpet? Is this correct?

Looks to me like you got it, csafe! Well done!

Salesperson: If it's not carpeted, this will work, because it's good for wood and tile

Strengthen: There's nothing other than those options.

I am a bit confused as to why A is correct. I get that it closes a logical gap however, I don't feel like the argument even goes that far. It's not like the conclusion is saying "a handheld vacuum cleans nearly all surfaces", it just says that it is good for wood and tile . So what if there are only three types of floors?

Actually, lounalola, the conclusion is the entire first sentence:

If your vacuuming needs are limited to cleaning small areas of uncarpeted floors, an inexpensive handheld vacuum cleaner is likely to be sufficient.

If all you care about is uncarpeted floor, and if the only options are tile and wood, and if this type of vacuum is good on tile and wood, then it stands to reason that this type of vacuum is likely to be sufficient. If A is true - wood and tile are the only things other than carpet that you need to clean, then the conclusion is much stronger. It sure would hurt if people need to clean brick, or concrete, or laminate, or marble floors, right?
