Do critical analysis of a research paper

Hi, I have four research papers. You need to select one paper and critically evaluate the selected paper in 2000 words. To clarify it more, you need to find flaw in the research paper and build an argument to support your point of view. Your deliverable would be 2000 words report on flaws of selected research paper. I hope you understand it. If you still have a doubt, please ask in your proposal. Also please mention in your proposal which research paper you have selected. Without this, your bid will not be considered. No plaigiarism. Deadline: 12 hours from the time of awarding the project. Budget = 20$ (Non-negotiable) You need to update me after writing every 500 words.
