The second graph on the top in C, there are more seconds then the graph shows.

The second graph on the middle row of B doesn’t stop twice. It is supposed to be in A, but since it doesn’t stop twice, the people who put it under be thought it was B since  it only stopped once.

The second graph in A is just wrong.

On C, the first graph on the second row goes strait up, even though the problem has different paces.

The graph on the third row of B has two dots on second one, and the second dot starts at ten.

On C, the second graph in the second row starts running witch is correct, but then it slows down and then gets faster, instead of the other way around.
