James says that the economic gap between rich and poor will widen. Why? Because there's an increasing division between computer literate and computer illiterate people, and the importance of computer literacy is only growing.

Ariel says that the increasing importance of computer literacy will not cause the economic gap between rich and poor to widen. Why not? Because companies will have to train nearly all workers in computer skills due to their increasing need for computer-literate employees. This will decrease the gap between the computer literate and computer illiterate.

We need a statement that James and Ariel disagree on. They disagree whether the need for computer literacy will cause the gap between rich and poor to widen. James thinks the need for computer literacy will widen the gap. Ariel thinks another factor, if anything, will widen the gap.
