A town is considering building a biodiesel power plant that would burn biomass to generate electricity. Which of the
following correctly lists an advantage and a disadvantage of this project?

a) Advantage: it could help get rid of unwanted waste. Disadvantage: there is no way to use the electricity created.

b) Advantage: it reduces dependence on fossil fuels. Disadvantage: it would emit pollution into the air.

c) Advantage: it is a commonly used energy source. Disadvantage: building the plant would attract new people to
the area.

d) Advantage: it would use energy from the sun and wind. Disadvantage: it is a non-renewable source of energy.

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.
