which piece of text uses this meaning of rare?
rare adjective uncommon
percy prefers to eat well - done beef and lamb, but myra prefers hers rare.
in the antique shop, mr. jones found a rare hardcover edition of mark twains life on the mississippi, published by james r. osgood & company in 1883.

Explanation:

We need to find the text where "rare" means "uncommon". In the first sentence, "rare" describes the doneness of meat (cooked lightly), not "uncommon". In the second sentence, a "rare hardcover edition" means the edition is uncommon (not easily found), so this uses "rare" as "uncommon".

Answer:

In the antique shop, Mr. Jones found a rare hardcover edition of Mark Twain's Life on the Mississippi, published by James R. Osgood & Company in 1883.
