A.I. Explanation:

Correct answer: as

Explanation: The word 'as' is used here to indicate a comparison, showing that some winds can move at a speed comparable to that of a racing car. This fits grammatically as it connects the two clauses effectively, maintaining the sentence's structure and meaning.

Meaning: 'As' in this context means 'in the same way' or 'to the same degree,' indicating that the speed of the wind is similar to that of a racing car.

Wrong options:

• to: The word 'to' indicates direction or destination, which does not fit the comparative context of speed in this sentence.
• for: The word 'for' suggests purpose or reason, which does not align with the comparative nature of the sentence.
• on: The word 'on' typically indicates a position or surface, making it unsuitable for expressing comparison in this context.

Correct answer: hour

Explanation: The word 'hour' is the correct unit of time for measuring speed in this context, as it is commonly used to express distances traveled over time. It fits grammatically and contextually, aligning with the phrase 'over 100 miles an.'

Meaning: 'Hour' refers to a unit of time equal to 60 minutes, commonly used to measure speed in miles per hour.

Wrong options:

• second: The word 'second' is too short a time frame for the context of wind speed, as it would imply an extremely high speed that is not typical for winds.
• minute: The word 'minute' is also a valid time unit, but it is less common than 'hour' for expressing speeds like 'over 100 miles.'
• micro second: The term 'micro second' is impractically small for this context, as it would suggest an unrealistic speed for wind.

Correct answer: faster

Explanation: The word 'faster' is the comparative form of 'fast,' which is appropriate here to indicate that the rate of heat loss increases due to wind. This fits grammatically as it correctly modifies the verb 'feel' in the context of the sentence.

Meaning: 'Faster' means at a greater speed, indicating that the body loses heat more quickly when it is windy.

Wrong options:

• slower: The word 'slower' implies a decrease in speed, which contradicts the context of losing heat more quickly in windy conditions.
• higher: The word 'higher' refers to an increase in elevation or level, which does not relate to the speed of heat loss.
• lower: The word 'lower' suggests a decrease in level or amount, which does not accurately describe the increased rate of heat loss.

Correct answer: know

Explanation: The word 'know' is the correct choice as it indicates the necessity for weather forecasters to have information about the wind's speed and direction. This fits grammatically and contextually, as it conveys the idea of awareness or understanding.

Meaning: 'Know' means to be aware of or have information about something, which is essential for forecasters in predicting weather conditions.

Wrong options:

• overshoot: The word 'overshoot' implies exceeding a target or limit, which does not fit the context of gathering information about wind.
• check: The word 'check' suggests verifying or inspecting, which is not as direct as 'know' in terms of possessing information.
• fix: The word 'fix' implies correcting or repairing, which does not relate to the need for understanding wind conditions.
