Read the following passage from a flight operations briefing:
'During pre-flight operations, technicians must immediately deactivate any auxiliary power unit showing signs of overheating. Because high-altitude turbulence is often unpredictable, automated stabilizers assist pilots in maintaining steady control. Ground crews routinely inspect the subterranean storage vaults beneath the runway apron to ensure fuel lines remain intact. When crosswinds arise during landing, automated flight controls counteract the lateral forces to keep the aircraft centered on the runway.'
Based on the prefixes, roots, and suffixes used in the passage, match each bolded word to its correct contextual definition.
- deactivateTo turn off or stop something from operating
- unpredictableNot capable of being foreseen or known in advance
- subterraneanLocated or existing beneath the surface of the earth
- counteractTo exert force against an opposing action to reduce its effect
Cevap
'deactivate' matches with 'To turn off or stop something from operating'; 'unpredictable' matches with 'Not capable of being foreseen or known in advance'; 'subterranean' matches with 'Located or existing beneath the surface of the earth'; 'counteract' matches with 'To exert force against an opposing action to reduce its effect'.
Each word's definition is derived by combining its constituent morphemes with the surrounding context clues: 'de-' indicates reversing or stopping an active machine; 'un-' and 'pre-' indicate conditions that cannot be known in advance; 'sub-' combined with 'terr' describes items located beneath the ground; and 'counter-' combined with 'act' denotes working in direct opposition to incoming forces.
