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: Intriguingly , a minor proportion of the SARS-CoV E protein was found to be modified by N-linked glycosylation on Asn 66 and inserted into the membranes once with the C-terminus exposed to the luminal side.

Output: finding


Input: Consider Input: Analyses performed with geNorm revealed that hypoxanthine phosphoribosyltransferase 1 ( HPRT1 ) and hydroxymethylbilane synthase ( HMBS ) were the two most stable reference genes in response to post-oviposition time alone ( POT ) or with nicarbazin treatment ( POT+N ) of laying hens.

Output: finding


Input: Consider Input: Injection of chicken embryo with the GLTSCR2-specific shRNA-1370 simultaneously or 24 h prior to infection with Newcastle disease virus ( NDV ) substantially reduces viral replication in chicken embryo fibroblasts.


Output: finding
