Orthodox medicine is ineffective at both ends of the spectrum of ailments. At the more trivial end, orthodox medicine is largely ineffective in treating aches, pains, and allergies, and, at the other extreme, it has yet to produce a cure for serious, life-threatening diseases such as advanced cancer and lupus. People turn to alternative medicine when orthodox medicine fails to help them and when it produces side effects that are unacceptable to them. One of the reasons alternative medicine is free of such side effects is that it does not have any effects at all. If the statements above are true, which one of the following can be properly inferred from them? ['Orthodox medicine will eventually produce a solution for the diseases that are currently incurable.', 'There are some medical conditions for which no orthodox or alternative treatment is effective.', 'There are some trivial illnesses that can be treated effectively by the methods of alternative medicine.', 'Practitioners of alternative medicine are acting in bad faith.']
