Magoosh	The Bluetail Moonbeam, endemic to the streams and rivers of Asia, is regularly imported into the United States by companies wishing to breed it for food. An infectious virus has been threatening Bluetail Moonbeam stocks in the United States. Even before a Bluetail Moonbeam develops any symptoms, biologists can establish the presence of the infection by an inexpensive test for antibodies in the fish's blood. Yet, after the instance of infection, antibodies take about four weeks to appear in the fish's blood, and the test will find no results before then. Catching a live Bluetail Moonbeam and shipping it to the United States takes a little more than a week. Once the Bluetail Moonbeam is in captivity, shippers can eliminate all new sources of infection, but unfortunately, some Bluetail Moonbeams might be infected days or even hours before being caught. Thus, even running the antibody test on each Bluetail Moonbeam entering the country would still allow infected fish into the American stocks.Which of the following, if performed by the government, could logically be expected to overcome the problem with the plan to limit the spread of this virus in the Bluetail Moonbeam?

Magoosh	The cafeteria of a certain elementary school provides a free lunch every day to the entire student body — a significant expense in the school's annual budget. A vice principal was exploring cost-reducing measures that would not compromise nourishment. A local Italian restaurant offered the school a large number of pizzas at a vastly reduced bulk rate. The pizzas were served one day, and afterward, the vice principal calculated that the cost of the pizza and delivery was slightly more than the average cost of typical cafeteria lunch day. Therefore, he concluded that the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant. Which of the following would be most useful for evaluating the conclusion drawn by the vice principal?

Magoosh	The blue-tipped puffer is a migratory bird that is found along the coast of this state in summer months. The puffers enjoy the seeds of Thomson's Mulberry trees; because these trees are plentiful in the state's Coastal Park, traditionally many blue-tipped puffers would be found in the park during summer months. Ten years ago, the grey fox, a primary predator of the puffer, was re-introduced into the park, and its numbers have been thriving. Over that time, we have seen many fewer puffers in the park during the summer months. Clearly, the puffers are choosing to spend their summers elsewhere. Which of the following would be the most important to determine in order to evaluate the argument?
