Example Input: Question: The pentose phosphate pathway produces: 
 Options:  <0> NADH and acetyl-CoA. <1> NADPH and ribose-5-phosphate. <2> NADH and ribose-5-phosphate. <3> Urea. <4> Ribulose-1,5-bisphosphate.
Example Output: biology

Example Input: Question: Plasma ICP is more suitable for rapid multielemental analysis than flame atomic absorption methods because: 
 Options:  <0> The linearity interval is not wide, which allows for very sensitive analyzes. <1> The ICP has several possibilities to introduce the sample using different types of nebulizers. <2> They use two photomultiplier tubes, one for the ultraviolet region and the other for the visible one. <3> It has load-coupled silicon solid-state detectors that allow simultaneous monitoring of a large number of lines, reducing analysis time, sample volume and improving detection limits. <4> It is not correct, because with the ICP plasma, multielemental analysis can not be done.
Example Output: chemistry

Example Input: Question: Which of the following drugs would be the most indicated initially in a patient with an obsessive-compulsive disorder?
