Mr Christian Okpara. Please learn not to steal other peoples work. This write up was plagiarized from the IAAF website. As a journalist with the Guardian, I would expect original articles from you. Even if you decide to go verbatim, be decent enough to provide proper referencing. People!!!! this is the link to the original article https://www.iaaf.org/news/news/shanghai-2015-diamond-league-women-100m. What a shame Sir!!!.
