Nathan thinks of a five-letter secret word. Mina tries to find out what the word is by saying five-letter words. After each guess, Nathan writes down five symbols that correspond to the letters of the guess.

• θ means the letter is in the secret word, in the same place.
• # means the letter is in the secret word, but in a different place.
• - means the letter is not in the secret word.

Mina’s guesses and Nathan’s replies to these guesses are shown in the table below.
