Although its name sounds like a possessive, the Ralphs chain of supermarkets does not include an apostrophe and is in fact named for its founder George Ralphs. Therefore, it is unlikely that the chain was given its name in an effort to invoke the feel of a local, owner-operated store.
Which of the following, if true, would most strengthen the argument above?
(A) None of the other supermarket chains owned by the Yucaipa Companies, which purchased the Ralphs chain in 1994, has a person's name as the store's brand.
(B) Supermarkets and other retailers often go by a founder's name as a way to create a locally-owned, community feel.
(C) The Ralphs name has remained unchanged since the store was founded in 1873, even though ownership of the chain has changed several times.
(D) When George Ralphs filed his initial permit for a business license for his first store, he omitted a company name and the licensing bureau simply used his surname to finish the paperwork.
(E) In many communities it is common for regular patrons of retailers to colloquially add a possessive apostrophe-S to store names, such as Kroger's or Ford's, that do not actually involve possessives in the official names.
As with any Strengthen question, here you should seek out the conclusion and be sure to notice its specific scope: here it is that it's unlikely that the Ralphs supermarket chain was given its name to convey the feel of a local, owner-operated store. Note that the question is specific to the one chain, Ralphs, and to the original reason it got the Ralphs name. This can help you eliminate choice A, which talks Ralphs' new ownership - not the group that gave the original name.
Choice B is also incorrect: remember, your job is to show that it is UNLIKELY that Ralphs was given its name to convey this idea of a locally-owned store, so it is not helpful to your conclusion that some supermarket chains DO give names for that reason.
Choice C simply gives more context about the name Ralphs - how long it has been around - but does not allow you to determine why the supermarket chain received its name.
Choice D is correct, as it proves that Ralphs did not receive its name intentionally at all: if the name were given because the founder did not provide a name on the registration form, then it could not have had the intent to create that feel of a local store.
And choice E is incorrect as it misses the scope entirely - this argument is about how Ralphs received its official name, not about what people tend to call stores colloquially.
