[00:-8.00]Howard Aiken.Two years later,
[00:-9.00]a new type of computer was built with electronic parts aclled valves.
[00:10.00]Modern computers use microchips instead of valves.

[00:45.00]Howard Aiken.True.   Question Six.
[00:46.00]Ten years later.a new type of computer was built with wlwctronic parts called valves.
[00:47.00]False.
[00:48.00]Two yeras later.a new type of computer was bilt with wlwctronic parts called valves.
[00:49.00]Question Seven Modern computers use valves instead of imcrochips.
[00:50.00]False.Modern computers use imcrochips instead of valves.
[00:41.82]Question Eight.These microchips are tiny but very efficient.True.
[00:31.87]Now imagine that you're Steven
[00:26.88]and you're writing a letter to a friendtelling him about some recent problems in your life.
