Example Input: Question: Point out the INCORRECT statement about the sexual misconduct that occurs in some victims of child sexual abuse: 
 Options:  <1> It is a common problem in children who have suffered sexual abuse. <2> It is a symptom that constitutes a diagnostic criterion of post-traumatic stress disorder and therefore it is expected to disappear if PTSD is properly treated by techniques such as exposure. <3> You can work with the parents and also directly with the children. <4> Your treatment may include a sexual education component also in prepubertal children. <5> The involvement of parents includes their duty to protect and keep the child safe.

Example Input: Question: The deviation of Beer's law by the use of non-monochromatic radiation can lead to deviations from linearity when representing absorbance versus concentration due to: 
 Options:  <1> Different molar absorptivities of the absorbent species. <2> Very similar molar absorptivities of the radiations of the polychromatic beam. <3> That the radiant power of the incident beam is modified. <4> That the use of a polychromatic beam always implies significant differences with respect to a monochromatic one. <5> That the relation of incident and transmitted powers is different.
