Q: 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".
Paragraph: The analysis presented in the paper, relies on an underlying epidemic model to obtain the infection probability r(f). This appendix presents two variants of the textbook SIR epidemic model, one with vital dynamics and one without. We derive a closed form solution for infection probability of an SIR model with vital dynamics which gives rise to the formulas used in the paper. Unfortunately, for an SIR model without vital dynamics, there is no closed-form solution. However, we show that, for diseases of interest and for realistic values of infection model parameters, the same formula can be used as an effective approximation for the true probability function. Using the notation in the paper, a vaccine's effectiveness is denoted by a parameter , where 0 < 1.
