Why do the data support or refute the scientists’ hypothesis that global warming is causing an increase in hurricanes? A.
The data refute the hypothesis because there is not a direct match between temperature change and number of hurricanes.

B.
The data support the hypothesis because when yearly temperature deviations are below normal the yearly number of hurricanes decreases.

C.
The data refute the hypothesis because the yearly change in temperature appears to be random when compared with the number of hurricanes.

D.
The data support the hypothesis because the trend of increasing number of hurricanes matches the trend of increasing global temperature change.

It really doesn't matter for any of the questions that you've listed.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
