On each page, the single KEYWORD is
blanked out. Read the whole text and
see if you can deduce it. (One or two pages
only have MORE than one word blanked. )

GO BACK and redo those you didn't get
first time, then repeat the exercise:

- tomorrow
- in two days' time
- in four days' time
- in eight days' time

... or until you can do them all perfectly and instantly ...
