IPS - always add inflation?? Schweser ex. 2 vol.2 Q1a

CFA Level III
#1

Question 1a in Schweser volume 2 mock 2 adds the inflation to the return requirement. It did not specifically mention that they would like to grow assets with inflation. Is it assumed that the individual is always interested in maintaining purchasing power of their portfolio?? If the question does not specifically state this should we still add inflation if given an inflation rate?

Thanks!

they asked for a nomial rate, so inflation has to be added.
