A.I. Explanation:

Correct answer: incident

Explanation: The word 'incident' fits grammatically as a noun that refers to an event or occurrence, which aligns with the context of air rage being recorded. It is singular and appropriately matches the article 'an' preceding it, indicating one specific event.

Meaning: An 'incident' is an event or occurrence, often one that is noteworthy or unusual, in this case referring to a specific case of air rage.

Wrong options:

• phenomena: 'Phenomena' is the plural form of 'phenomenon' and does not fit here as it implies multiple occurrences, while the sentence refers to a singular event.
• offense: 'Offense' refers to a violation of a law or rule, which does not accurately describe the event of air rage itself, making it contextually inappropriate here.
• crime: 'Crime' implies a serious violation of law, which is not the case in this context as the passenger was not charged, thus making it an unsuitable choice.

Correct answer: established

Explanation: The word 'established' is the correct choice as it indicates that something has been determined or set as a standard. It fits grammatically in the past tense, aligning with the context of the sentence discussing a conclusion drawn about air rage.

Meaning: 'Established' means to set up or lay down a principle or rule, in this case referring to the determination of jurisdiction for prosecuting air rage incidents.

Wrong options:

• predicted: 'Predicted' implies forecasting something that will happen in the future, which does not fit the context of determining a fact about jurisdiction that has already been established.
• found: 'Found' suggests discovering something that already exists, which does not accurately convey the idea of setting a standard or rule as 'established' does.
• discover: 'Discover' means to find something new or previously unknown, which does not align with the context of confirming existing rules.

Correct answer: increased

Explanation: The word 'increased' is the appropriate choice as it indicates a rise in the frequency or amount of air rage incidents. It fits grammatically in the past tense and aligns with the context of discussing growth over time.

Meaning: 'Increased' means to have become greater in number or amount, indicating that air rage incidents have become more common since the 1990s.

Wrong options:

• decreased: 'Decreased' means to have become less, which contradicts the context of the sentence that states air rage has grown significantly.
• evolved: 'Evolved' implies a gradual development or change, which does not specifically indicate a rise in incidents as 'increased' does.
• rose: 'Rose' is a verb that indicates an upward movement but is less precise in this context compared to 'increased,' which clearly denotes a quantitative change.

Correct answer: predicted

Explanation: The word 'predicted' is suitable as it indicates a forecast or expectation about future events. It fits grammatically in the passive voice and aligns with the context of anticipating future problems related to air rage.

Meaning: 'Predicted' means to say what will happen in the future based on evidence or reasoning, in this case referring to expectations about air rage incidents.

Wrong options:

• hoped: 'Hoped' implies a desire for something to happen, which does not convey the certainty of forecasting that 'predicted' does.
• hardly: 'Hardly' suggests something is unlikely to happen, which is the opposite of what the sentence intends to convey about future problems.
• occurred: 'Occurred' is in the past tense and indicates something that has already happened, which does not fit the context of discussing future expectations.

Correct answer: passengers

Explanation: The word 'passengers' is the correct choice as it refers to individuals traveling on an aircraft. It fits grammatically as a plural noun, matching the context of discussing those affected by air rage incidents.

Meaning: 'Passengers' are individuals who travel in a vehicle, particularly in this context, those on an airplane.

Wrong options:

• flight: 'Flight' refers to the act of flying or a scheduled journey, which does not identify individuals and is therefore contextually inappropriate here.
• attendant: 'Attendant' refers to a person who assists passengers, but does not encompass all individuals involved in air rage incidents, making it too narrow.
• pilot: 'Pilot' refers to the person flying the aircraft, which does not fit the context of discussing those who may exhibit air rage.

Correct answer: assault

Explanation: The word 'assault' is the correct choice as it refers to a physical attack, which fits the context of describing the most common experience related to air rage incidents. It is a noun that aligns with the legal implications of such behavior.

Meaning: 'Assault' means a physical attack or threat of attack, particularly in a legal context, indicating the severity of actions that can occur during air rage incidents.

Wrong options:

• injury: 'Injury' refers to harm or damage to a person, which is a consequence rather than the action itself, making it less precise than 'assault.'
• punch: 'Punch' is a specific type of physical attack, which is too narrow and informal compared to the broader legal term 'assault.'
• slap: 'Slap' is also a specific action and does not encompass the range of aggressive behaviors that can occur, making it less suitable than 'assault.'
