499 When a person is choking, but still conscious and standing, the person helping should form a fist with both hands and place the thumb side of the fist under the patient's belly button to apply Heimlich Maneuver.(A)O(B)X

500 About 8% of a normal adult's weight comes from the blood, but the number is higher for male than for female. A person will go into shock quickly after losing 1,500CC of blood. After losing a huge amount of blood from the aorta, the person might die in 1 minute.(A)O(B)X

651 Before straight-line braking, both the front and back brakes of a motorcycle should be used simultaneously to prevent drifting off track and shorten the braking distance.(A)O(B)X

652 When using the front brake of the motorcycle, do not brake suddenly and completely to avoid too much pressure on the front shock absorbers. The rear wheel will spin off the ground and cause a crash.(A)O(B)X

654 A motorcycle should decelerate to a safe speed before going around a curve. Hold the throttle to maintain a constant speed while entering the curve to produce thrust from the rear wheel and pass through the curve steadily.(A)O(B)X

655 When riding on the mountain road, a motorcycle should decelerate to a safe speed before going around a curve. Determine the correct entry point, lean forward in the same direction as the motorcycle, and hold the throttle steady to maintain the backward thrust during cornering.(A)O(B)X

656 The essential body movements for going around the curve include shifting the hips before entering the curve, leaning forward in the same direction as the motorcycle, relaxing the left shoulder, left elbow and left wrist when turning toward the left and relaxing the right shoulder, right elbow, and right wrist while using the right hand as the main control when turning to the right. Keep the throttle steady to maintain the backward thrust during cornering.(A)O(B)X

657 When the centrifugal force creates inertia during a curve on mountain roads, latch onto the throttle and lean forward in the same direction as the motorcycle. Do not release the throttle and do not brake.(A)O(B)X

658When the centrifugal force creates inertia that pulls you away during a curve on mountain roads, release the throttle and brake immediately.(A)O(B)X

659 Releasing the throttle completely while going around a curve would result in the loss of thrust in the rear wheel and creating centrifugal force that causes inertia.(A)O(B)X
