Yes they arent as wild as they are told to be
Shakespeare's chief source for Macbeth was Holinshed's Chronicles (Macbeth), who based his account of Scotland's history, and Macbeth's particular, on the Scotorum Historiae, written in 1527 by Hector Boece. im pretty sure this is right
That would be a practical exercise. Practical means the actual doing or use of something rather than with theory and ideas. So it would apply to real life situations.
Hope this helps!
