I must admit I often find the 'short lessons' on here a little confusing because of the coloured lines. This one is particularly bad. I cannot see if the text with green lines is supposed to relate to the text with orange lines above it or below it. Essentially, why are the coloured lines there? They only confuse. Marking explanations with one colour and examples with another is pointless; we can see what is what. What we cannot see is what pertains to what. It would be fine if you gave some examples with red lines then an explanation also with a red line, so we know it refers to the 'red lined' examples. Then, further examples with a different colour together with an explanation with the same colour. This way we know what refers to what.
