2.SAFETY PRECAUTIONS( )
A:预防措施 B:警告 C:安全预防措施 D:安全警告
答案:AI参考:正确选项是【C:安全预防措施】。\n\n根据问题中的描述,选项中只有C“安全预防措施”符合语境,因为它包含了“安全”和“预防措施”两个关键词。而其他选项的含义与问题描述不符。A选项“预防措施”虽然包含了“预防”的含义,但不够具体;B选项“警告”与问题描述无关;D选项“安全警告”虽然包含了“安全”和“警告”两个关键词,但“安全警告”通常用于提醒人们注意潜在的危险或风险,而不是用于描述某种措施。因此,C选项是正确答案。'

A:Master dim and test B:Instrument lights C:Indicators D:Lighted push-button switches
答案:AI参考:正确答案是C:Indicators。\n\n选项A是主控开关的调节和测试按钮;选项B是仪表灯;选项D是发光型按键开关,这三者都可以在题目描述中找到相对应的位置,但是它们并不属于题中描述的“不是仪表板灯”的那一类,所以无法构成符合逻辑的正确答案。选项C中的“indicators”(指示灯)能够正确解释题目中需要表达的含义,并且它的范围更加广泛,包括各种仪表盘上的指示灯等。因此,选项C是正确答案。'
6. What light supply light to help maintenance personnel and ground crews. ( )
A:Passenger compartment lights B:Exterior lights C:Cargo and Service compartment lights D:Flight compartment lights
答案:AI参考:正确答案是B:Exterior lights。\n\n根据题干中的描述,需要一种帮助维护人员和地面工作人员进行维护工作的照明设备,而选项B中的“Exterior lights”即外部照明灯,可以提供足够的照明,帮助维护人员和地面工作人员进行工作。因此,选项B是正确答案。选项A的“Passenger compartment lights”是客舱照明灯,选项C的“Cargo and Service compartment lights”是货舱和服务舱照明灯,选项D的“Flight compartment lights”是飞行舱照明灯,都不符合题干描述。'
7.Which system supplies pressure to the landing gear extension and retraction? ( )
A:wheels B:hydraulic system C:brakes D:energy absorbers

8. 选装( )?
A:IDG B:OPTION C:APU D:HP
答案:AI参考:正确选项是【B:OPTION】。\n\n根据问题描述,这里需要选装的是某个选项,而B选项"OPTION"是汽车、电子产品等中常见的一个选项名称,表示可选的配置或者功能。A选项"IDG"、C选项"APU"、D选项"HP"都不是表示选装的选项。因此,B选项是正确答案。'
9.Visually check areas below with no damage, scratch, dent, deformation, lightning strike, fluid Leakiness, missing or loose parts and fastener, obstruction of inlets/outlets.( )
