【答案解析】[听力原文]
M: Claire, this is a prescription for Wintressol, for your heartburn. I want you to take one pill three times a day. Don"t take the medicine on an empty stomach.
W: Dr. Roberts, Wintressol is a brand-name medicine, tight? My insurance only allows me to buy genetic medicine.
M: In that case, I"ll make a note for the pharmacist. Now, the generic medicine is less powerful, so take two pills at a time instead of one.
