The 5th and 6th scenario go together and the intention is to illustrate the difference in finding issues in the 2 scenarios. The first scenario is a replica of the chaos first experienced by player with 2 Alphabets removed. The player needs to find the missing Alphabets as quick as possible. Here there is a shift countdown and the timeout set, so that the player does not go on forever.
In the 6th scenario the payer sees the Set, Standardised and Sequential with the same two Alphabets removed. This time it should be an extremely quick exercise to spot the missing Alphabets.
