In a certain code, 'ja ko ri' means 'open the window', 'ri mu te' means 'close the door' and 'te ja ri' means 'open the door'. What is the code for 'window'?

Explanation

1. 01

   'the' is in all three sentences; 'ri' is the only code in all three, so 'the' is 'ri'.

2. 02

   'open' is in the first and third sentences; apart from 'ri' they share 'ja', so 'open' is 'ja'.

3. 03

   The first sentence 'ja ko ri' then leaves 'ko' for 'window'.
