"Changes in inventories go a long way, for instance, toward explaining why first

quarter real GNP was ahead of a year earlier by a meagre 1.7 percent." What

must have been happening to inventories during the first quarter?

a) rising because of unexpectedlyhigh output

b) falling because of unexpectedlylow output

c) rising because of unexpectedlylow aggregate demand

d) falling because of unexpectedlyhigh aggregate demand

Should the correct one be a ? It seems to me that first

quarter real GNP is higher than before
