I don’t understand the reference ‘TPO 10’

I have found that test here:

I’m sorry to have to tell you that the quality of the test is awful. There are nonsensical phrases and sentences like this all the way through it.
Unless you have a more accurate original, as an example of standard correct English, this is seriously flawed.

Thanks a lot.I guess,too. It happens a lot that the scripts of TPO includes some flows.
