Right, for this little exercise one needs observant ears. Yes, ears. You see, whoever—or whatever—narrates this small video has a very strange way of doing it. His/its diction is oddly mechanical, to say the least and some of the words are barely comprehensible. Yet it is English, I’m sure of that!
Apart from the above, the whole thing is very boring. And I say that as one very interested in John Holand, 1st Duke of Exeter . If you listen to the end, you’ll deserve a medal.
