In this task, you are given a sentence from the research paper and your task is to classify the given sentence into the following categories: Background (Why is this problem important? What relevant works have been created before? What is still missing in the previous works? What are the high-level research questions? How might this help other research or researchers?), Purpose (What specific things do the researchers want to do? What specific knowledge do the researchers want to gain? What specific hypothesis do the researchers want to test?), Method (How did the researchers do the work or find what they sought? What are the procedures and steps of the research?), or Finding (What did the researchers find out? Did the proposed methods work? Did the thing behave as the researchers expected?). 

Input: Consider Input: Here , we show that p53 represses expression of the rRNA methyl-transferase fibrillarin ( FBL ) by binding directly to FBL.

Output: purpose


Input: Consider Input: We have examined the requirement for ribonucleotides and ribonucleotide triphosphate hydrolysis during early events in the membrane integration of two membrane proteins : the G protein of vesicular stomatitis virus and the hemagglutinin-neuraminidase ( HN ) glycoprotein of Newcastle disease virus.

Output: purpose


Input: Consider Input: but higher procalcitonin strongly correlated with increased probability of bacterial pathogens , particularly typical bacteria.


Output: finding
