How do you start a thesis sentence with the subject on computers? Is this sentence a thesis?

Computers are becoming more useful.

Good start, but not quite a thesis statement.

A thesis statement tells what your paper is about.

Include your reasons that computers are becoming more useful...(usually three reasons which will become your body of your essay)

Example:
Due to advances in technology computers are becoming more useful because they are very reliable, easily store data....

To start a thesis sentence with the subject on computers, you can consider the following approach:

1. Decide on the specific aspect or idea related to computers that you want to explore in your thesis.
2. Craft a sentence that clearly presents your main argument or claim about that aspect. This sentence will serve as your thesis statement.

For example, if you want to discuss the impact of computers on modern society, your thesis sentence might look like this:

"Computers have revolutionized modern society, transforming various industries and reshaping the way people communicate, work, and access information."

Addressing your second question, the sentence "Computers are becoming more useful" is not a thesis statement. While it does touch upon the subject of computers, it does not present a specific argument or claim that you will explore and support throughout your thesis. A thesis statement should be specific and concise, providing a clear focus for your research or essay.
