Question

The task presents a short-answer prompt with an encrypted quote and asks who said it. There are no answer options to evaluate, so we cannot perform option-by-option analysis as we would for a multiple-choice question.

Step 1: Identify the structure of the prompt. It asks to guess who said the encrypted message: "Ovd fvb kv hufaopun pz ovd fvb kv lclyfaopun". The after-the-dash note, "Thyaoh Iljr", likely a signature or a corrupted author name, but without clarification it’s also part of the puzzle.

Step 2: Outline a decryption approach. In many cases, quoted encrypted messages use simple ciphers (for example a Caesar shift) or a substitution cipher. A solid first step is to try common single-shift Caesar decryptions by shifting each letter backward by 1, 2, 3, and so on through 25, watching for recognizable English words or phrases. If none of the shifts yield a meaningful phrase, one should test other standard cipher types (e.g., Vigenère with a short key, or a rearrangement/cipher typical in puzzles), or look for a known plaintext pattern.

Step 3: Consider whether the provided answer makes sense. The suggested answer (If you do nothing is if you do everything - Malala Yousafzai) appears to be a quotation attributed to Malala Yousafzai, but the exact phrasing may be misquoted or altered. Since the encrypted text could decode to something else, one cannot confirm the attribution without successfully decrypting the message and matching it to a known quote by a specific person.

Step 4: Explain why the lack of options matters. Because there are no listed answer choices, there is no straightforward way to confirm correctness by comparing each option. Verification must come from successfully decrypting the message (to reveal the actual quote) and then matching it to its author.

Step 5: Provide practical next steps for the student. Try the following sequence:
- Attempt Caesar shifts for the encrypted string: substitute each letter with the one a fixed number of positions earlier in the alphabet, wrapping around as needed, and see if any shift yields an intelligible English sentence.
- If a shift yields a plausible plaintext, identify the quote and its attributed author, then check if that attribution aligns with known quotations from Malala Yousafzai or another figure.
- If no Caesar shift works, consider alternative classical ciphers (e.g., substitution, Vigenère) or look for a clue in the extra text "Thyaoh Iljr" which might be another ciphered signature or a hint about the method used.

Step 6: Concluding observation. Without decrypting the message to a clear English sentence, we cannot reliably determine the author. The proposed answer—attributing the quote to Malala Yousafzai—remains unverified until the encryption is cracked and the plaintext matches a known quotation from that person (or another individual).
