Passage
Scientists have observed rapid eutrophication of a local lake, at a rate much higher than that of other lakes in the area.
Eutrophication is the aging of a lake, resulting in increased levels of plant life and accumulated sediments, brought on by a build-up of nutrients such as nitrates and phosphates.
Rapid eutrophication is harmful, as it leads to the dying off of cold water fish such as trout. Researchers performed the following experiments to determine the possible source of the increased nitrates and phosphates.
Experiment 1
Scientists suspected that one source of nutrients was a feeder stream which intercepts run-off from farmland where pesticides and animal waste are found. Water samples were obtained over several days from that stream (Feeder A) as well as another feeder stream (Feeder B) not near the farm. Results are displayed in Table 1.
Experiment 2
The scientists also surmised that another possible source of harmful nutrients entering the lake was run-off from a golf course adjacent to the lake where fertilizers were applied.
Water samples were obtained from the lake at various distances (0 meters, 100 meters and 200 meters) from the golf course on four successive days, and the levels of chlorophyll, phosphates, and nitrates were measured. The results are depicted in Table 2.
Q. If scientists sampled lake water from a third location 300 meters from the golf course, which of the following would most likely represent the average phosphate level found there?
  • a)
    35.3 mg/L
  • b)
    30.6 mg/L
  • c)
    26.2 mg/L
  • d)
    20.1 mg/L
Correct answer is option 'D'. Can you explain this answer?

The best answer is d. Table 2 shows the concentration of phosphate from different days at 0 meters, 100 meters, and 200 meters away from the golf course. To answer this question, you must find the average phosphate concentrations from each distance, as follows:

As the distance away from the golf course increases, the phosphate concentration decreases.
The only answer choice with a concentration less than 24.9 mg/L is answer choice d.
