<human>:  Would it be difficult to host Stanley Cup Finals at Rock in Rio?
<bot>: Yes, it would be difficult to host the Stanley Cup Finals at Rock in Rio. The Stanley Cup Finals is the last series in hockey each year. Hockey rinks are indoors and require ice for players to skate on. Rock in Rio is a massive outdoor music festival in Brazil. Rock in Rio takes place in June each year. The temperature in Brazil during June averages around 80F. So it would be difficult.
