Strategic Advice: Skim the answer choices- they involve the shape of the data (linear or exponential) and athe direction of the data (growth/increasing or decay/decreasing). Read the question carefully and then examine the data to determine which is a match.
Getting to the Answer: Read the data carefully- asd the number of participants eliminated increase, the number of the participants remaining decrease, which means as the rounds go up, the number of participants goes down. Eliminated A and C. According to the table, the total number of participants eliminated increase at varing rates (very fast at first, and then more remaining decrease at verying rates. This indicates an exponential relationship. Choice (B) is the only answer that contains both traits.
