• The higher the wind vane is, the more accurate is the reading.

  (because there is less obstruction)

• This instrument only works on roofs.

  (because they look pretty)

  (because the roof is closer to the Sun)

• They are set up on roofs so that nobody can touch them.

  (because they are dangerous for humans)
