TOW (& Answer)...

The question was what does the aum measure?  The aum is a measure of liquid.  One aum equals 120 quarts or 60 magnums.  As the later number suggests, the aum is used in the measure of wine.

The question (& answer) were found on p. 118 of For Good Measure by William D. Johnstone.  The book was published by Holt, Rinehart and Winston in 1975…. Old but still interesting.
