Context: This weekend I was a model patient for a intern / registrar exam on early trauma management in rural settings . I got to play a 19-year old who went through the windscreen with bilateral mandibular fracture , rib fractures , collapsed lung , fractured pelvis + dislocated hip ... to name but a few of the major injuries - basically , a complete mess . I got paid $ 75 for the mornings ( plus food ) and I essentially just had to lie there with a bunch of fake blood all over me !

Question: Why might I have been paid for pretending to be a patient ?
Options:
0. Because without the payment , people might not want to pretend to be uninjured because of the idea of getting hurt .
