Among the conclusions of Chapter Eight's survey of the evidence on international technology transfers is that:

A) developing countries gain more technology from trade links with developed economies than they do from trade links with other developing economies.
B) international flows of technology are far from instantaneous, and in general it takes longer for technology to move across borders than within countries.
C) small developed economies and all developing economies depend on foreign sources for most of their technological progress.
D) developed economies absorb more foreign technology than developing economies.
E) All of the above.
