Difficulty: EasyDrawing Logical Conclusions

Read the following technical safety procedure. Based on the cause-and-effect relationships described, what word correctly completes the logical conclusion?

Answer:Aircraft maintenance hangars utilize static grounding cables attached to the fuselage during refueling operations. These cables discharge static electricity buildup safely into the hangar floor, preventing flammable aviation fuel vapors from igniting. Therefore, if ground crew members conduct refueling while the grounding cable is disconnected, the likelihood of a fuel fire will 【increase】.

Answer

increase (or rise / be higher)
The passage explicitly states that grounding cables prevent fuel vapors from igniting by safely discharging static electricity. When refueling takes place without the grounding cable attached, static charges can accumulate near flammable vapors, causing the likelihood or risk of a fire to increase.

Step-by-Step Solution

1
Identify the safety function of the grounding cables from the passage.
Grounding cables discharge static electricity into the floor to prevent flammable fuel vapors from igniting.
Understanding the protective role of the equipment is necessary to evaluate what occurs when it is not used.
2
Deduce the logical outcome when refueling occurs with the cable disconnected.
Without the grounding cable to dissipate static charges, spark risks remain present, which directly raises the probability of a fuel fire.
Connecting the absent safeguard to the resulting hazard completes the logical deduction.
