## Answer

Wind is air moving around. Some winds can move **as** fast as a racing car, over 100 miles an **hour** . Winds can travel around the world. Wind can make you feel cold because you lose heat from your body **faster** when it is windy. Weather forecasters need to **know** the speed and direction of the wind. The strength of wind is measured using the Beaufort scale from wind force when there is no wind, to wind force 12 which can damage houses and buildings and is called hurricane force.

## Explanation

The article "an" before blank 2 is your clue. Only "hour" starts with a vowel sound, because its h is silent. "Minute" and "second" would need "a." Blank 1 completes the comparison "as fast as," so the first word must also be "as," not "to" or "for."

## Hints

- Look at the words immediately before and after the blank to determine if you need a preposition, a unit of time, or a comparative adverb.
- Consider the scientific context; for example, how do we measure the duration of speed, and what verb fits the requirement for weather experts?
