As Mary wasn't at school today, her teacher decided to send her the homework by text message using his old mobile phone. Unfortunately the teacher did not know how to use the predictive text facility so the wrong words were sent. Can you figure out the correct answers? Predictive Text entry, allows you to enter text by pressing only one key per letter. As you enter a word, the phone will automatically compare all of the possible letter combinations against a built in dictionary of words, and determine which word you intended to type. When it guesses incorrectly, you will get the type of result seen here. Other words have been substituted for the ones we want.
