Which choice provides information that best supports the claim made by this sentence [4]?
Here, option A is the correct answer because by mentioning the “specialized” methods used in repair shops, it suggests that repairing goods is seen as a specialty rather than as a common activity. This connects logically with the “rare” repair shops introduced just before the underlined portion. B, C, and D are incorrect because none provides information that supports the claim made in the sentence.
