At the end of each day, a retail clothing stores inventory is checked

Question

At the end of each day, a retail clothing store’s inventory is checked by a handheld device that uses radio frequency identification (RFID) to identify each item of clothing. The device automatically records the date and time of each scan. However, the store’s owner has discovered that some items that were sold during the day are still being recorded in the inventory at the end of the day. Clearly, the handheld device is not functioning properly.

Which of the following, if true, most seriously undermines the owner’s conclusion?

A. The store’s sales staff sometimes forgets to remove the RFID tags from items of clothing when they are sold.
B. The store’s inventory includes many items that are very similar to each other.
C. The device is designed to scan every item in the store in less than one minute.
D. The store sells more items of clothing during the holiday season than at other times of the year.
E. The store’s owner relies on the device to check the inventory because the store is too large to check manually.

The owner’s conclusion is that the handheld device is not functioning properly because some items that were sold during the day are still being recorded in the inventory at the end of the day.

However, option A provides  an alternative explanation  for why this might be happening. If the sales staff sometimes forgets to remove the RFID tags from items of clothing when they are sold, then the device will still record these items as being in inventory, even though they have actually been sold. This explanation is consistent with the evidence that the owner has observed, and it therefore undermines the owner’s conclusion that the device is not functioning properly.

The other options are not as relevant to the owner’s conclusion.

Option B simply states that the store’s inventory includes many items that are very similar to each other. This does not explain why some items that were sold during the day are still being recorded in the inventory at the end of the day.

Option C states that the device is designed to scan every item in the store in less than one minute. This is also not relevant to the owner’s conclusion, as the device is still recording items that have been sold.

Option D states that the store sells more items of clothing during the holiday season than at other times of the year. This is also not relevant to the owner’s conclusion, as the device is still recording items that have been sold, regardless of when they were sold.

Option E states that the store’s owner relies on the device to check the inventory because the store is too large to check manually. This is also not relevant to the owner’s conclusion, as the device is still recording items that have been sold, regardless of how the owner checks the inventory.

Therefore,  the answer is (A) .

Hope it helps.

Option A is the best option among the others.
However, there is still a gap that if the inventory is checked using the RFID scanners, then the RFIDs of the items sold will not be scanned at the end of the day since the items and the tags will not be in the store. (the customer would have taken the item with them)
The items will thus not be reflected in the inventory at the end of the day. It would probably show as missing. May actually strengthen the conclusion in a way that the scanner is showing missing item in the inventory as present in the inventory.
Experts, would like to know your POV.

Paras96 · Answer

To undermine the owner's conclusion that the handheld device is not functioning properly, we need to find an alternative explanation for why some sold items are still being recorded in the inventory at the end of the day. Let's analyze each option:

A. The store’s sales staff sometimes forgets to remove the RFID tags from items of clothing when they are sold. 
 - This option provides an alternative explanation for why sold items might still be recorded in the inventory. If staff members forget to remove RFID tags, the device would continue to scan the tagged items, leading to incorrect inventory records. This weakens the conclusion that the device itself is malfunctioning.

B. The store’s inventory includes many items that are very similar to each other.
 - This information about the similarity of items in the inventory does not directly address the issue of items being recorded as unsold. It is not directly relevant to the conclusion.

C. The device is designed to scan every item in the store in less than one minute.
 - This option provides information about the device's scanning speed but does not explain why some sold items are still being recorded in the inventory. It is not directly relevant to the conclusion.

D. The store sells more items of clothing during the holiday season than at other times of the year.
 - This information about seasonal variations in sales does not address the issue of items being recorded as unsold. It is not directly relevant to the conclusion.

E. The store’s owner relies on the device to check the inventory because the store is too large to check manually.
 - This option provides information about the owner's reliance on the device for inventory checks but does not explain why some sold items are still being recorded. It is not directly relevant to the conclusion.

Option (A) is the most appropriate answer because it offers a plausible alternative explanation for the issue at hand. If sales staff forget to remove RFID tags from sold items, it would lead to the incorrect recording of these items in the inventory, which weakens the owner's conclusion that the device is malfunctioning.

This was also my doubt. If the items have been sold, how are they still at the availability of the store's reach to be scanned at all? My inventory's items would be only the ones which are unsold. I wouldn't take off the RFID tag and still keep it in the store only.
