Premise: For example, if we compare the annual growth rates of mail volume for period 1993-97 shown in Column (11) of Tables 1 and 4 we can see  (a) the 2.0 percent annual decrease of total HH-to-HH volume in Table 1 has been augmented to a 3.3 percent annual decrease of per-household volume in Table 4; (b) the 6.8 percent annual decrease of total HH-to-NHH volume in Table 1 has been augmented to a 8.0 percent annual decrease of per-household volume in Table 4; (c) the 0.2 percent annual increase of total NHH-to-HH volume in Table 1 has shrunk to a 1.2 percent annual decrease of per-household volume in Table 4; and (d) the 7.1 percent annual increase of total NHH-to-NHH volume in Table 1 has shrunk to a 5.7 percent annual increase of per-household volume in Table 4.

Hypothesis: Annual growth rates are shown in column 121 of tables 1 and 4.
Relation: contradiction
