The task states:
In order to alleviate congestion configure R1 so that it does not send more
than 128Kbps of ICMP traffic out this interface.  Allow for a burst of 1/4th
of this rate.

The answer uses NBAR to match ICMP and uses policy-map to police cir 128000
bc 4000.

Why bc is 4000?  I thought 1/4th of this rate is 32000?
