Passage I
As an apple ripens, it undergoes changes in its firmness (the maximum force that can be applied to the apple without puncturing its skin) and in its production of volatile (readily vaporized) compounds. A study examined how the storage time at 1 °C affected the firmness and the volatile abundance (the concentration of volatile compounds produced) of 4 different varieties of apples. Table 1 shows how the average firmness of each variety changed over time at 1 °C. Table 2 shows how the average volatile abundance of each variety changed over time .at 1 °C. (Note: All the apples were of identical maturity at 0 days.)

4. Based on Table 2, which of the following graphs best shows the average volatile abundances of the 4 varieties of apples at a storage time of 60 days?
Your Answer is
Correct Answer is G
Explanation
Looking at the 60 days column in table 2, it is found that the average volatile abundance of the four kinds of apples is 6.1, 9.8, 1.2, and 9.1 respectively, so the G option is consistent
