I dont really want to fail this test again. Please give it your best try

Renita analyzed two dot plots showing the snowfall during the winter months for City A and for City B. She found that the median snowfall is 5 inches less in City A than in City B and the mean snowfall is about 2 inches less in City A than in City B.

Which explains why there is a difference in the measures of center for the sets of data?
A. One set of data has more variation than the other.
B. There are no outliers in either set.
C. In each set, the distribution is clustered around one value.
D. The modes must be the same for each set.

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
