“Hey, Kitty, what’s wrong? Why aren’t you talking to ________I__________?”

“You went to the cinema with Lisa Parker yesterday,” Kitty was almost crying.

How do people learn the news? About a century ago people got _________INFORM_________ from newspapers since they were the only mass media that existed in those times.

“If I don’t invent a very good excuse, she ________CALL__________ my parents.” Paul thought.
