Input: Consider Input: Question: The gas used to generate the ICP plasma (coupled induction plasma) is:
Options: <0> Hydrogen for being diatomic, chemically inert and with a low ionization energy. <1> Oxygen because it is diatomic, highly reactive and with a high ionization energy. <2> Argon, being monatomic, chemically inert and with a high ionization energy. <3> Xenon, being monatomic, highly reactive and with a low ionization energy. <4> None of the above is correct, because the gas used is helium.

Output: chemistry

Input: Consider Input: Question: In relation to the treatment of a non-smoking woman with non-small cell lung carcinoma, stage IV adenocarcinoma, which of the following statements is correct?
Options: <0> The determination of the epidermal growth factor receptor (EGFR) mutation is required. <1> Entry Gefitinib is the standard treatment without EGFR determination. <2> It has a standard treatment based on camptothecins. <3> Any type of standard chemotherapy is valid. <4> There is no predictive factor for this disease.

Output: medicine

Input: Consider Input: Question: In the human eye:
Options: <0> Photoreceptors contact the vitreous humor. <1> The accommodation is due to the increase in the curvature of the cornea. <2> The pigmentary epithelium participates in the regeneration of rhodopsin. <3> The cones and rods are distributed homogeneously throughout the retina. <4> The greatest refractive power is in the lens.
