IV. Fill in each numbered blank with ONE suitable word
How long would it take you to multiply 24,683,579 by 97,538,624? Probably several minutes at least. An electronic computer could do this (26) _______ in a tiny fraction of a second. In five minutes a fast electronic computer can do (27) _______ calculating than a person could do with a pencil and paper in all his life. Calculating machines have been used for a long time.

Of course, electronic computers are complicated. Early ones had vacuum tubes and were huge. Then transistors took the (33) _______ of vacuum tubes, and the computers could be smaller. Now miniaturized parts make (34) _______ possible for them to be still smaller. Computers are sometimes called electronic brains. Writers often joke about a time in the future when computers will do all our thinking for us. The idea is foolish. Computers cannot plan and build themselves. They cannot gather facts and figures. These must be fed into them. They can do (35) _______ with the facts and figures they are not built to do. But these machines are wonderful proof of how clever people are at working out ways of helping themselves.
