In rheumatoid arthritis, the body' s immune system misfunctions by attacking healthy cells in the joints causing the release of a hormone that in turn causes pain and swelling. This hormone is normally activated only in reaction to injury or infection. A new arthritis medication will contain a protein that inhibits the functioning of the hormone that causes pain and swelling in the joints. The statements above, if true, most strongly support which one of the following conclusions? ['Unlike aspirin and other medications that reduce pain and swelling and that are currently available, the new medication would repair existing cell damage that had been caused by rheumatoid arthritis.', 'A patient treated with the new medication for rheumatoid arthritis could sustain a joint injury without becoming aware of it.', 'Joint diseases other than rheumatoid arthritis would not be affected by the new medication.', "The benefits to rheumatoid arthritis sufferers of the new medication would outweigh the medication's possible harmful side effects."]
