To answer your questions accurately, I need to rely on general knowledge of the "Boom and Bust" population cycles of rabbits and Myxomatosis effects, as I can't see the graph mentioned. Here’s how to approach the questions you provided:
Question 1: In which of the following years was the rabbit population in South Australia most dense? You should look for a peak in the population curve on the graph. Since I don't have access to the graph, I can’t definitively say which year had the highest density, but typically, rabbit populations peaked in the mid-20th century. If there’s a noticeable peak in the listed years (1936, 1952, 1975, 2000), that would be the answer. Based on historical data, the population was often at very high levels around the early 1950s, so if that's reflected in your graph, 1952 would likely be your answer.
Question 2: Based on the graph, what can you infer about the rabbit population after the fleas were introduced? European Rabbit Fleas were introduced to help control rabbit populations by spreading Myxomatosis. Typically, after the introduction of such measures, one would expect an increased death rate due to disease spreading more effectively. Therefore, I would infer that after the fleas were introduced, "the rabbit death rate increased" would be the most likely response, as the intent was to control the population through disease.
If you have specific data or points from the graph, that could help refine these answers more accurately!
