The answer that will not result in a congruent figure is the statement about moving the points so they are 2/3 as far from the y-axis.
If you take the 2 top points on the trapezoid and test this, you will see they will not end up the same distance apart. Currently, they are 3 units apart.
2/3 of 6 = 4 units from the y-axis
2/3 of 3 = 2 units from the y-axis
This new figure would only be 2 units apart on the top.
