1 - sentence
2 - copy and paste
3 - make spelling error
Explanation : In order to write a research paper, the objectives of writing it should be very clear. We should not write irrelevant sentences that don not relate with the aim of the paper. While writing the paper in our own words, we should ensure not to copy and paste from other journals and keep the grammar right. The sentences should be well phrased and we should get our paper checked by someone for the purpose of proofreading.
