Passage II
The gypsy moth, which is native to Asia and Europe, was accidentally introduced to the northeastern United States in 1869. Gypsy moth larvae (caterpillars) eat tree leaves and have caused serious damage to forest ecosystems in the United States. Figure 1 shows the times of the year that the different stages of the gypsy moth life cycle occur. Figure 2 shows the percent of 1,000 test plots having light, moderate, or heavy defoliation (leaf loss) due to gypsy moth larvae each year from 1979 to 1983. Table 1 shows the average percent defoliation by gypsy moth larvae for individual tree species in the test plots in 1981.
8. Based on Table 1, in the test plots in 1981 the average percent defoliation of which of the following tree species was 10 times the average percent defoliation of yellow poplar trees?
Your Answer is
Correct Answer is G
Explanation
Look at table 1, the value corresponding to yellow poplar is 5. A tree 10 times more serious than it should correspond to 50, you can find scarlet oak
