We repeat the four properties stated in the Comment on Activity 3:
The graph of `F` must be tangent to the `t`-axis on the left.
The graph of `F` must increase steadily.
The slope of the graph of `F` is steepest where `ftext[(]t text[)]` is largest, i.e., at the mean.
The graph of `F` must be tangent to the line `y = 1` on the right.
Which of these four properties of the graph of the normal distribution `F` are shared by the graph of the Cauchy distribution function
