Gabi and Luke want to use a code to send secret messages to each other. In the code, each letter of the alphabet is represented by a one-digit number, as follows: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 For example, the word BELL would be written in the code as 2-5-2-2. To test the system, Gabi writes four words in the code and sends them to Luke. Luke tries to decode them, and gets the following answers: TOOK DONE HIGH SORT Luke is confident that he has three of these words correct, but he is unsure about the other one. Which word is Luke unsure about? A TOOK B DONE C HIGH D SORT |
