Episode 4: Don't introduce `sort -r` when teaching piping #1027

In Episode 4, Pipes and Filters, we introduce students to sort and sort -n.

My issue is with the exercise titled "Pipe Reading Comprehension". In it, we not only show students the longest command-chain they've seen, but we also ask them to interpret sort -r without any introduction or previous exercise related to it.

In my opinion, the cognitive load is high enough reading four commands piped together. Adding a new sort option to figure out is unhelpful to students' understanding of this part of the lesson.
