In an informational article, the thesis statement must be supported by facts, details and explanations related to the thesis.

All paragraphs of the article should explain and support the thesis since that is what will give the text unity and what will increase the reader's interest and motivate him/her to keep reading. Since facts can be verified, they can help strengthen the thesis statement. Statistics and explanations can also be used in order for the thesis to make sense to the reader.
