premise: A crowd behind a fence is watching bicyclists ride up a hilly road with motorcycles behind them. hypothesis: A crowd behind a wire fence watches bicyclists and motorcyclists ride up a hill while cheering them on.
neutral: Not all fences are wire fences, even ones that crowds can see through. Picket fences and plastic mesh fences, for example. A crowd could be doing something other than cheering- they could be hurling insults.
