Task: Question Answering
Input (English): 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.
Output (English): 1
