In this task, you are given a paragraph (from a research paper) and your task is to classify each sentence of the paragraph (assume n sentence) into the following categories: Background, Purpose, Method, Finding/Contribution, or Other. Return the output in this format: 1 - category of sentence 1, 2 - category of sentence 2, ..., n - category of sentence n; where each number indicates the order of the sentence. The categories can be identified using the following questions: 
 Background: - Why is this problem important? - What relevant works have been done before? - What did the previous works miss? - What are the high-level research questions? - How might this help other researchers?
 Purpose: - What specific things do the researchers want to do? - What specific knowledge do the researchers want to know? - What specific hypothesis do the researchers want to test?
 Method: - How did the researchers do it or find it out? - What are the procedures and steps of this research?
 Finding/Contribution: - What did the researchers find out? Did the proposed methods work? - Did things behave as the researchers expected?
Other: put every text fragment that does not fit into any of the categories above here. Put a sentence here if its not in English, is not part of the article, contains numbers and dates, is a caption of a figure or a table, is a formatting error, or you are not sure about it.

Input: Consider Input: Conclusion: Italy is experiencing one of the highest CFR from the COVID-19 pandemic in the world. Time delay adjusted CFR in all the regions in Italy except the Island region were higher than that estimated for Wuhan, China. The CFR in Northwest Italy is 2.5-fold higher than that in Wuhan. Our finding reflects the need of urgent medical support in the Northwest region and the appropriate planning and supplies procurement in other regions of Italy with . CC-BY-NC-ND 4.0 International license It is made available under a author/funder, who has granted medRxiv a license to display the preprint in perpetuity.

Output: 1 - finding, 2 - finding, 3 - finding, 4 - finding, 5 - finding, 6 - finding


Input: Consider Input: This is the eighth article in our series on the history of pediatric specialties. Dr. Shulman describes the history of infectious diseases over the centuries. Many of these major killers of children were conquered by research that led to understanding the causes of these diseases and eventually to establishing means of prevention and treatment. Dr. Shulman also describes the organizations and publications that have furthered the development of treatment, research and education in this specialty. The future of this field includes the challenges of understanding and treating infectious diseases in immunocompromised children and in developing countries where infectious disease is still a major killer.

Output: 1 - background, 2 - purpose, 3 - background, 4 - purpose, 5 - purpose, 6 - finding


Input: Consider Input: Results: Plasmids differed in core-expression capacity: mouse fibroblasts transfected with pCMVcore, pCMVcoreIRES and pCMVcoreKozak expressed 0.22 ± 0.18, 0.83 ± 0.5, and 13 ± 5 ng core per cell, respectively. Single immunization with highly expressing pCMVcoreKozak induced specific IFN- and IL-2, and weak antibody response. Single immunization with plasmids directing low levels of core expression induced similar levels of cytokines, strong T-cell proliferation


Output: 1 - finding, 2 - finding, 3 - finding, 4 - finding, 5 - finding
