Question 80-70-
- For each data egory, the following bars are shown:
- recycling process 1
- recycling process 2
- All values are approximate.
- The Lithium recovered data for the 2 egories are as follows:
- Type A:
- recycling process 1: 30%
- recycling process 2: about halfway between 50% and 60%
- Type B:
- recycling process 1: about halfway between 30% and 40%
- recycling process 2: about halfway between 70% and 80%
- Type A:
A team of scientists wants to improve the recycling of two of the most common types of lithium-ion batteries used in electronic devices. The team tested two new processes that involve grinding battery materials and aluminum foil together. The highest percentage of lithium recovered in the tests was closest to blank

Answer explanation
Choice A is the best answer because it most effectively uses data from the graph to complete the statement. The graph shows test results for two new battery recycling processes used with two types of lithium-ion batteries, type A and type B. According to the graph, recycling process 2 recovered the highest percentage of lithium in the tests: recovering about 75% from lithium-ion battery type B.
Choice B is incorrect because, according to the graph, the highest percentage of lithium recovered in the tests was 75%, not 10%. In fact, none of the tests recovered exactly 10% of lithium from a recycling process. Choice C is incorrect because, according to the graph, the highest percentage of lithium recovered in the tests was 75%, not 45%. In fact, none of the tests recovered exactly 45% of lithium from a recycling process. Choice D is incorrect because, according to the graph, the highest percentage of lithium recovered in the tests was 75%, not 20%. In fact, none of the tests recovered exactly 20% of lithium from a recycling process.
