TASK DEFINITION: In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".
PROBLEM: Paragraph: Background: The goal of this study was to evaluate whether a live attenuated poliovirus vaccine (OPV) has clinically relevant interfering effect with non-polio infections causing otitis media in young children. Methods: Open trial in which the intervention group (64 children) received OPV at the age of 2, 3, 6 and 12 months. The control group (250 children) received IPV (inactivated polio vaccine) at the age of 6 and 12 months. Clinical symptoms were recorded by a questionnaire at the age of 3, 6, 12, 18 and 24 months. Results: Otitis media episodes were less frequent in the OPV than in the control group. A significant difference was seen at the age of 6-18 months (IRR = 0.76 [95% CI 0.59-0.94], P = 0.011) and was particularly clear among children, who attended daycare (IRR 0.37 [95% CI 0.19-0.71], P = 0.003). Conclusions: OPV provides some protection against otitis media. This effect may be mediated by viral interference with non-polio viruses. 
 Title: Viral interference induced by live attenuated virus vaccine (OPV) can prevent otitis media

SOLUTION: False

PROBLEM: Paragraph: The envelope spike (S) proteins of MERS-CoV and SARS-CoV determine the virus host tropism and entry into host cells, and constitute a promising target for the development of prophylactics and therapeutics. Here, we present high-resolution structures of the trimeric MERS-CoV and SARS-CoV S proteins in its pre-fusion conformation by single particle cryo-electron microscopy. The overall structures resemble that from other coronaviruses including HKU1, MHV and NL63 reported recently, with the exception of the receptor binding domain (RBD). We captured two states of the RBD with receptor binding region either buried (lying state) or exposed (standing state), demonstrating an inherently flexible RBD readily recognized by the receptor. Further sequence conservation analysis of six human-infecting coronaviruses revealed that the fusion peptide, HR1 region and the central helix are potential targets for eliciting broadly neutralizing antibodies.

SOLUTION: False

PROBLEM: Paragraph: Acute pharyngitis is a common illness in both children and adults, caused by a wide variety of microbial agents. In children, approximately 20% of pharyngitis is caused by group A beta-hemolytic streptococci (GABHS); in adults, 5% of pharyngitis is due to GABHS. The signs and symptoms of infection are variable, ranging from mild sore throat with minimal physical findings to high fever and severe pain. The differential diagnosis of GABHS pharyngitis is extensive. Most cases of acute pharyngitis in both children and adults are caused by viruses. The gold standard diagnostic test for GABHS remains the throat culture. It is important to select appropriate candidates for culture to maintain the sensitivity of the test. Penicillin is still recommended as first-line treatment for documented GABHS infections. Prompt treatment is important to prevent serious sequelae of infection.
