Select topic sentence of below paragraph.
Because electronic computers are now used for data processing, the general public believes it is a mysterious, complicated science and that computers are giant brains. Both of these assumptions are incorrect. A computer is essentially a high-speed adding machine that performs the functions that are programmed into it. If the input data is even slightly changed, the computer will not be able to function until it is programmed to accept the changes. The business operations it performs are impressive only because of the extremely fast manipulation speed, but the majority of these operations have been used for decades. In contrast to humans, computers can perform repetitive calculations without becoming tired or bored.
- A computer is essentially a high-speed adding machine.
- A computer is mysterious.
- A computer is impressive because of its extreme speed.
- A computer is superior to man in lots of ways.
Hint:
The title summarizes the main idea or ideas of your study. A good title contains the fewest possible words needed to adequately describe the content.
The correct answer is: A computer is essentially a high-speed adding machine.
Answer - A computer is essentially a high-speed adding machine.

Social networking sites such as MySpace, Facebook, and Twitter have grown in popularity among people of all ages in recent years. Despite some people's fears that young people are becoming crouching androids glued to their computers, research shows that the vast majority of friendships are still maintained offline. Offline friendships have more interdependence, depth, understanding, and commitment, but online friendships can develop some of these characteristics over time. The majority of online friends are wary of disclosing personal information. This does not seem to apply to people who have a negative view of themselves and others; instead, they appear to share more information, possibly in an attempt to become more self-confident in their interactions. Surprisingly, even in online friendships, people appear to gain more satisfaction when they befriend people their own age and location.

Poverty is a result of Africa's problems, not a cause of them. What African countries require; the West cannot supply. They require individual liberty. This entails a political system that ensures private property rights, free markets, honest government, and the rule of law. The majority of Africa's poverty is self-inflicted. Some may disagree because their college professors taught them that colonialism's legacy explains third world poverty. That is absurd. Canada used to be a colony. Australia, New Zealand, and Hong Kong were also present. In fact, the United States, the world's richest country, was once a colony. Third-world countries such as Ethiopia, Liberia, Nepal, and Bhutan, on the other hand, were never colonies and are home to some of the world's poorest people.

Some people learn to play a musical instrument simply for the sake of having fun. They'd like to play it with their friends or in a band. Others learn to play an instrument as a part of their culture. Certain instruments, such as the guitar in Spain or the oud1 in the Middle East, are popular in certain cultures. People will sometimes learn to play an instrument because they believe it will make them smarter. They want to keep their minds occupied, and music is unlike the work they think about all day. To summarize, there is clearly more than one reason why people choose to play a musical instrument.

Select the topic sentence of the below paragraph.
Most metals rust when they come into contact with oxygen. Aluminium is a unique metal because it does not rust. Instead, it has a different reaction with oxygen. It creates a tough surface film that prevents rust. Things that spend a lot of time outside are frequently made of aluminium. This is why aluminium is used in the manufacture of automobiles and aeroplanes. It can also be used as a construction material. However, aluminium lacks the strength of steel. When it comes to strength, even rusted steel outperforms aluminium.
