Hi @mdshahin786. This article is quite similar to another article which has been posted yesterday. You can check it out here. If the similarity was intended, then this is an act of plagiarism. You need to know that, plagiarism is unacceptable especially if it is a STEM-related article. If you want to post an article which is related to a particular source, please ensure that:

• You write it by using your own words.
• Cite the article's content references.
• Cite the image's source

I would advise you to refrain from committing plagiarism in the future. If you have any problem regarding STEM-related articles, you can join steemSTEM Discord Channel, and we will be glad to assist you.
