71.依據游離輻射防護安全標準,有關緊急曝露人員之劑量規定,下列何者正確? (A)為搶救生命,劑量限値為單一年劑量限度的5倍 (B)為防止嚴重危害,劑量限値為單一年劑量限度之20倍 (C)緊急曝露所接受之劑量,應與職業曝露之劑量合併記錄 (D)為減少大量集體有效劑量,劑量限値為單一劑量限度之2倍

1007.What is this warning light?(A) ABS brake warning light. (B) Brake system warning light. (C) Low fuelwarning light.

1008.What is this warning light?(A) Low engine oil pressure warning light. (B) Low fuel pressure warning light.(C) Low coolant level warning light.

1009.When a warning light on the dashboard illuminates while driving, the driver should identify thecorresponding vehicle system. Which of the following pairings is correct? (A) Charging warning lightcorresponds to the engine combustion system; engine malfunction light corresponds to the batterycharging system; brake warning light corresponds to the braking system. (B) Charging warning lightcorresponds to the alternator and battery charging system; engine malfunction light corresponds toengine operation-related systems; brake warning light corresponds to the braking system. (C) All threewarning lights are uniformly controlled by the onboard computer, indicating only a general vehicleabnormality, and there is no need to distinguish individual systems.
