A large apartment building in a city was assessed by a city environmental bureau for the comparatively high consumption of electricity in the building, and the landlord was threatened with a possible fine if the consumption did not drop significantly in a specified period. While all built-in appliances and lighting in common areas are energy efficient, the landlord found, upon doing an inspection, many residents were using older portable heaters that are not very energy efficient. The landlord decided to send each resident a detailed letter about the electric energy consumption of these older portable heaters, recommending newer more energy efficient models that could be purchased at local stores. He hopes the letter will motivate enough residents to buy more energy efficient heaters.
Which of the following, if true, would provide most support for the prediction that the landlord's letter will have its intended effect?

Art historian: Successful forgeries tend to be those most recently painted. While such a phenomenon may sound counterintuitive, a forger is able to exploit current modes of aesthetics to create paintings that appeal to the eye of his or her contemporaries. This very quality, however, is what makes those paintings seem amateurish to subsequent generations. As a result, a majority of forgeries are identified as such roughly twenty-five years after their creation. Which of the following is an assumption upon which the argument rests?

Forty miles to the west of Tucson, a developer attempted to develop an "oasis" glade in the Sonoran Desert. He created a glade that, the developer claims, is as lush and plant-filled as the ambient 35° C temperatures allow. In particular, the developer planted several native fruit-bearing plants, such as prickly-pear cactus. Once the glade was established, a number of desert birds and mammals would regularly inhabit the glade, often eating most of the fruit that falls from the plants. The considerations given best serve as part of an argument that:
