Teacher: In this task, you are given a question and answer options for that question. Using this information, you have to classify each text into different topics: medicine, nursery, psychology, chemistry, pharmacology, biology.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Question: A distension is defined as: 
 Options:  <0> Soft tissue injury. <1> Forced movement of abrupt production. <2> Injury by stretching a muscle. <3> Injury of the joint capsule. <4> Interruption in the continuity of a bone.
Solution: nursery
Reason: Distension means Bloating and swelling in the belly area. It does not have much to do with chemistry, psychology, pharmacology, biology and medicine. Hence, the correct topic is nursery.

Now, solve this instance: Question: What taste do you think can mask the bitter taste of an oral solution: 
 Options:  <0> Licorice. <1> Apricot. <2> Vanilla. <3> Anise. <4> Raspberry.
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
