Which of the following, if true, would most weaken the objection? ['More and more sockets of other brands have begun to add lightning protection components.', 'Survey shows that most consumers are not concerned about lightning strikes on their circuits.', 'In the known cases of home appliances that have been struck by lightning, none of the home appliances that use the new socket have been damaged.', 'In the forthcoming national standard, all socket products are required to contain lightning protection components.']
