In this task, you are given a sentence from the research paper and the category to which it belongs. Your task is to classify whether the given category is correct or not by providing "True" and "False", respectively. Here are the definitions for the 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?). ",

[EX Q]: Sentence: but clinical signs alone do not allow for viral identification. 
 Section: background
[EX A]: True

[EX Q]: Sentence: The presence of Ile allows for separation between 0-frame MQANFLGKI and -1-frame MQANFLR peptides. 
 Section: finding
[EX A]: True

[EX Q]: Sentence: Moreover , S118 of wild-type protein formed H-bonds with T134 and G135 but these interactions were lost in PRRSVAV ( S118A ) and PRRSVES ( S117A ) indicating that the substitution of important H-bond interaction in PRRSVAS ( S118A ) and PRRSVES ( S117A ) affected the flexibility around the catalytic triad , conformation and proteolytic activity. 
 Section: purpose
[EX A]:
False
