I would say knowing how to operate the controls, and knowing how to work a computer will result in success in online learning.
Answer:
I was at school. I hadn't seen my colleagues in a long time and I was very excited. I wanted to share all the madness, the fun done on vacation. I had missed my best friend because he went to his grandparents and I didn't see him. I packed my things and put them in my closet. I arranged all the books and notebooks. Suddenly, I noticed a red plaque to the left of my closet. In fact, it was a red note on the door of my friend's closet. I was really wondering what he could write there. I couldn't resist and read. It was a message to me. "I'm sorry I can't be with you on the first day of school. I'm sick and I had to stay home. See you next week anyway. Signed, your friend." I was very happy when I read the message. I thought he was with his grandparents. I can't wait to see you.

La idea central es lo que intenta transmitir el autor sobre el texto, con ayuda de la idea principal y los detalles
Explanation:
Television was never one person's vision -- as early as the 1820s, the idea began to germinate. Certainly by 1880, when a speculative article appeared in The Scientific American magazine, the concept of a working television system began to spread on an international scale.
At the dawn of the twentieth century, there were a few American laboratories leading the way: Bell, RCA, and GE. It wasn't until 1927, when 21-year-old Philo T. Farnsworth, beat everyone to the punch by producing the first electronic television picture. This historic breakthrough catapulted him into a decades-long patent battle against major corporations, including RCA and CBS. The battle took its toll on everyone and RCA’s David Sarnoff brilliantly marketed this invention to the public and became known as the father of television -- while Philo T. Farnsworth died in relative obscurity.
Experimental broadcast television began in the early 1930s, transmitting fuzzy images of wrestling, music and dance to a handful of screen. It wasn't until the 1939 World's Fair in New York, where RCA unveiled their new NBC TV studios in Rockefeller Plaza, that network television was introduced. A few months later, William Paley’s CBS began broadcasting from its new TV studios in Grand Central Station.
Now that television worked, how could these networks profit on their investment? Who would create the programming that would sell their TV sets? How would they dominate this new commercial medium, without destroying their hugely profitable radio divisions?
