BOY BREAKS INTO М15 COMPUTER SYSTEM
Max White is only ten years old, but he has the honour of being the youngest person 1_   [A, B, C, D, E, F, G]_______________ .
Max, who is eleven next month, created havoc with M15's computer system and nearly caused a national emergency. Max just thought he was having fun. Max was just six years old when his father bought him his first computer, which he used to play children's games on, but he quickly moved on to more exciting activities. Max, 2   [A, B, C, D, E, F, G] ______, had soon infiltrated all his father's confidential files. Max was too young to understand the seriousness of what he was doing. Early in the morning he would creep into his father's office, closing the door gently behind him, and turn on the computer. He realized that different codes gave him access to certain files, and he soon discovered files 3   [A, B, C, D, E, F, G]__________ . Keith Hamilton, 4   [A, B, C, D, E, F, G]____________, monitored the progress of this unknown spy. He wondered what sort of super intelligence could break the
codes 5   [A, B, C, D, E, F, G]___________ . But what he couldn't understand was why the spy made no attempts to close all the files behind him, thus making it obvious espionage was taking place. The reason became apparent when they discover their so-called secret agent. Max didn't know how to close down the files, only how to
open them. This incident has been an expensive lesson for M15, 6   [A, B, C, D, E, F, G]_____________. Max doesn't really understand why everyone is making such a fuss, but he has promised to stick to Super Mario and Nintendo from now on.

In two weeks, the small group of Odeo tried to think of a new idea for a business. Biz Stone and Jack Dorsey came up with an idea for a microblogging service. They thought it would be fun to have an online service that let you see status updates of what your friends were doing. They built a prototype and presented it to the Odeo team. They began to work together on building Twitter.
