YOU SAID:
When the oats have found a home, they shall move
INTO JAPANESE
オート麦が家を見つけたら、彼らは移動しなければならない
BACK INTO ENGLISH
If oats find a house, they have to move
INTO JAPANESE
オート麦が家を見つけたら、彼らは移動しなければなりません
BACK INTO ENGLISH
Once the oats find a house, they have to move
INTO JAPANESE
オート麦が家を見つけたら、彼らは移動しなければなりません
BACK INTO ENGLISH
Once the oats find a house, they have to move
That didn't even make that much sense in English.
