In the dense graph limit theory, the topology of the set of graphs is defined by the
distribution of the subgraphs spanned by finite number of random vertices. Vera T.
Sos proposed a question that if we consider only the number of edges in the spanned
subgraphs, then whether it provides an equivalent definition. We show that the answer
is positive on quasirandom graphs, and we prove a generalization of the statement.
