Question

Study the sentences below. The information looks like a paragraph, but it’s not. Can you figure out why?

An Italian named Marconi invented the radio. The first radio was called a wireless. During World War II, most people got their news from listening to a radio. Today, people often listen to radio programs in their cars. Cell phones have changed the way people live. Everywhere you go these days, you see people talking on cell phones. Some people think cell phones make life more dangerous. They can cause accidents. People shouldn’t talk on their cell phones while driving a car. Watching television can be a waste of time. Many people spend many hours every day watching television. It would be better if people would talk to each other. That would be a good idea. Some of us might discover that our neighbor is more interesting than our favorite television series.

Answer 1

A real paragraph has only one main topic. The topic sentence, which contains the main idea of a paragraph, should help tie all of the other sentences together with the topic.

Answer 2

Here's why. List the topics. It starts with who invented the radio. It goes on to tell what the use of the radio was during WWII. Then it switches to automobile radios and from there to cell phones (a life altering invention) and their dangers while driving.

I don't see the connection, but we are now watching television which jumps to talking to each other and then back to TV and the series you can find on TV.

There is about 10 subject switches in that one paragraph. Normally that would not even be passible writing, let along good writing.
