Why is Option B not possible in this case Carcass? Here the act of "Many other venues, including shopping malls, are considering adopting holographic displays" does seriously weaken the point made by the Consumer Advocates right?

Explanation

The consumer advocates are urging stores not to use the displays because they claim the technology is:

Intrusive to patrons.
May increase minor accidents involving shopping carts.


To weaken the advocates' position, we need to undermine either claim or show that the risk/annoyance is less serious than they suggest.

Choice (E) directly weakens the first claim. If patrons quickly become accustomed to the holographic displays, then the displays are not persistently intrusive-the initial distraction or annoyance fades with familiarity. This removes or significantly reduces the advocates' main objection, making it less reasonable to ban the technology.

Why the Others Are Incorrect

(A) The holographic displays are expensive to install and maintain. - This weakens Displayco's marketing pitch (since stores might not want to pay for them), but it actually supports the advocates' position by giving stores a financial reason to avoid the technology, not weakening it.
(B) Many other venues are considering adopting holographic displays. - Irrelevant. Popularity elsewhere does not affect whether the displays are intrusive or unsafe in supermarkets.
(C) Accidents in supermarkets that are serious enough to cause injury are rare. - The advocates specifically warn about minor accidents. The rarity of serious injuries does not address the risk of increased minor collisions or near-misses that could still be a nuisance or liability.
(D) Supermarkets tend to be low-margin businesses. - This strengthens Displayco's profit argument (stores need higher profits), but it does not weaken the advocates' claims about patron intrusion or safety. The advocates are concerned about customer well-being, not store profitability.
