Now that you have the heights of all eight blades of grass, calculate the average height of the grass.
Record the average height of the grass in Table A of
your Student Guide.
What is the average height?
cm

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.

Where's the statements?
