In daily life, some people save trouble when taking pills. After putting the pills in their mouths, do not drink water or just take a sip of water, and then swallow hard, even if they have finished taking the medicine. Some people think that this way of taking medicine is not desirable. Which of the following, if true, would best support these people's views? ['Increasing the amount of water you drink will reduce the concentration of the drug.', 'Drink a lot of water while taking the medicine, which can speed up the speed of the medicine through the pharynx and esophagus into the stomach.', 'Some drugs, because of the low solubility of metabolites, are easy to precipitate in the urinary tract and cause other symptoms, so patients need to drink at least 1500 ml of water a day during the medication.', 'When taking the medicine, drinking too little water can cause the pills to stay in the esophagus for a long time and even cause side effects.']
