Who writes these things???

Just sitting down at work, to run through an online training module, and the first screen mandates the following:

Navigating through DWiT requires the following skills:

• The ability to use a web link
• The ability to close a browser window
• The ability to use the Back and Forward buttons on a web browser.

What sort of genius writes these training materials, and given it is online, web based training, how the hell did I manage to get to this particular screen if I don't have the above abilities?
