Task: Question Answering
Input (English): While wind surfing near the seaside community of Port Harbor, a young man is killed by a giant Great White Shark. Author Peter Benton and professional shark hunter Ron Hammer realize the truth, but ambitious governor William Wells refuses to accept that a shark threatens their community. Fearing that a canceled wind-surfing regatta would derail his gubernatorial campaign, Wells has shark nets installed. But the sounds of teenagers splashing in the surf leads the shark to rip through the nets. The next day, the shark plows through the wind surfers, knocking them off their boards. But rather than eat the scattered teenagers, the shark targets the governor's aide and eats him.The governor can no longer hide the truth. Benton and Hammer head out on the sea, planning to feed the shark dynamite and cause it to explode. But the shark traps them in a cave, and the men have to use their dynamite just to escape. Meanwhile, Benton's daughter Jenny and some of her friends head out on a yacht, armed with some steak and a shotgun, intending to shoot the shark. Instead, its powerful bites on the bait knocks Jenny into the water. Her friends pull her aboard, but not until the shark bites off one of her legs. Governor Wells's son was one of the friends she went out with, and Benton blames him for her injury. Determined to do something right, Wells sets out in a helicopter armed with a steak, apparently intending to hoist the shark into the air and suffocate it.
