Read the following excerpt from a speech given by a national leader: The price of our current war is high; it costs money and it
costs lives.
But it does not cost our pride. It does not cost the guilt that
would arise from knowing that we did nothing to intervene
while our neighboring nations fell to despotic leaders.
It does not cost the terror of knowing that our allies are
unstable. It does not cost the fear that we, too, will be next
to fall.
Which sentence most accurately explains why the speaker's use of parallel
structure is effective in this passage?

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
