Part 3: Substitution Cipher In this part, we have yet another intercepted communication. And this time, it is thought that the communication is encrypted using a substitution cipher. What is shown below is the intercepted cipher text. We observe that the characters of the English alphabet are encrypted, and other characters are left alone. What is the plain text corresponding to the FIRST sentence of the cipher text? [4 marks] Rhs bmwrtxqsmrw ests jw xwsvsww jw hbw wi-gjvvsk gtse.
