📝 Answered - Short simple statement about their everyday life. Data downloaded on 2/19/2020 from hitps://ourworldindata.org/grapher/iteracy-rate-adults?tab=chart&time=1973..2016. | Year | 1976 | 2001 | 2012 | | ---- | --------- | --------- | --------- | | Literacy Rate | $63.2 \%$ | $86.7 \%$ | $94.5 \%$ | When answering the questions below, round to four decimal places in your intermediate computations. Use interpolation or extrapolation (whichever is appropriate) to predict the literacy rate in Bolivia in 1992. Round your answer to one decimal place. Use interpolation or extrapolation (whichever is appropriate) to predict the literacy rate in Bolivia in 2050. Round your answer to one decimal place. Is your 2050 prediction realistic? You must select all correct responses at the same time to receive credit for this problem. A. Yes, the 2050 prediction is realistic because it was made using a mathematical formula. B. Yes, the 2050 prediction is realistic because it is possible for a literacy rate to exceed $100 \%$. C. No, the 2050 prediction is not realistic because the literacy rate cannot exceed $100 \%$. D. No, the 2050 prediction is not realistic because the literacy rate will not grow at the exact same rate for more than 40 years.
