A higher Science skill will reduce the number of words that you have to choose from.
Brackets are {}, [], <>, and (). The bracket pairs can contain any number of characters between them. The easiest way to find a bracket pairs is to slowly move your cursor across every character on the terminal screen. Bracket pairs and all of the characters in between will automatically be highlighted. You may want to save a bracket pair or two in case you need them before your last attempt.
Use any remaining bracket tricks. If you’ve saved any brackets, you can use them now to try to get another try added back to your tally, or to remove enough options so that you know which word to pick. Exit the terminal and start over. When you leave the terminal by clicking the power button, you can reset the process. The words will be shuffled and you’ll be starting from scratch, but you’ll get all of your tries back and won’t get locked out. Blindly try to guess the fourth word. This is rarely recommended, due to the fact that you can easily lock yourself out. Consider exiting and retrying instead.
