Consider the string abbccddeee. Each letter in the string must be assigned a binary code satisfying the following properties: 1. For any two letters, the code assigned to one letter must not be a prefix of the code assigned to the other letter. 2. For any two letters of the same frequency, the letter which occurs earlier in the dictionary order is assigned a code whose length is at most the length of the code assigned to the other letter. Among the set of all binary code assignments which satisfy the above two properties, what is the minimum length of the encoded string?

Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it. Awareness means the capacity to see a coffee pot and hear the birds sing in one's own way, and not the way one was taught.

Maybe he will be an ornithologist when he grows up.
The passage implies that when the boy starts his 'education' he will _____ .
