Directions:Read the passages and choose the best answer to each question.PassageA researcher has conducted two experiments to test the rate of pinecone production in the Pinus palustris Miller (a type of pine tre e).Experiment 1P. palustris Miller seeds were collected from 5 different populations (A1, A2, A3, A4, A5) each of which was from a different site (S1, S2, S3, S4, S5).The seeds were grown under controlled conditions in a greenhouse. 300 of these seedlings from each population were chosen at random. Each set of seedlings was divided into 30 groups with 10 seedlings in each group.The seedlings were planted in marked cylindrical containers which were then placed at each of the 5 sites. Figure 1 shows the procedure for A1.Table 1 shows the number of pinecones that were produced on each tree.The researchers also collected data on the root structure of the trees. From the information they collected they came up with the following formula relating the root structure in inches to the number of pinecones produced: number of pinecones = 0.037 + 0.147 (root thickness) Statistical analysis indicated that this equation was accurate.Experiment 2P. palustris Miller seeds were collected and grown in the same manner as in Experiment 1. When the seeds had grown into seedlings, 150 containers were prepared with 5 A1 seedlings and 5 seedlings from either A2, A3, A4 or A5. Seven containers for each of the 4 combinations were planted at each site.Table 2 shows how many pinecones were produced on each A1 plant.Q.A student wanted to produce the greatest number of pinecones from 6 A1 trees, using the procedures from Experiment 2. Which plants and site should the A1 trees be combined with to achieve the desired results?
