Example Input: Question: How is the correction of an erroneous amino acid incorporated in the process of translation in the ribosome carried out? 
 Options:  <0> There is no possibility of elimination of an amino acid in the synthesis of proteins. <1> Through the aminoacyl peptidase activity of the ribosome. <2> A dipeptidase removes the wrong amino acid, before proceeding with the synthesis. <3> Thanks to the fact that amino acids are energy-rich molecules. <4> There is a post-translational sequence review system.
Example Output: pharmacology

Example Input: Question: What simple reinforcement programs produce a more stable response pattern ?: 
 Options:  <0> Those of fixed ratio. <1> Those of variable reason. <2> Those of fixed interval. <3> Those of variable interval. <4> All reinforcement programs produce similar response rates.
Example Output: psychology
