The following appeared as part of an article in a health club trade publication:"After experiencing a decline in usage by its members, Healthy Heart fitness center built an indoor pool. Since usage did not increase significantly, it appears that health club managers should adopt another approach—lowering membership fees rather than installing expensive new features."Discuss how well reasoned you find this argument. In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

As part of a joint planning process, two museums – Museo metropolitan (MM) and the Fundacion arte (FA) – have decided to require that future exhibits at each museum be directly connected to the strengths of their permanent collections. MM's strengths are East Asian printmaking, 19th-sentury European painting, and 18th-century US painting and sculpture; the FA's strengths are 20th-centuru US painting, 20th-century jewelry, and art from 14th-century South America.In addition, MM's next exhibit must be devoted to something other than European or US art and be restricted to the 20th-century. FA's next exhibit must be devoted to art that is abstract, or at least art that is not fully representational (e.g. Semiabstract or semi representational), preferably including at least some art by US women.For each of the two museums, select a work that could be included in that museum's next exhibit without violating any of its requirements for exhibits. Make only two selections, one in each column.
