Among the more effective kinds of publicity that publishers can get for a new book is to have excerpts of it published in a high-circulation magazine soon before the book is published. The benefits of such excerption include not only a sure increase in sales but also a fee paid by the magazine to the book's publisher.
Which of the following conclusions is best supported by the information above?

The Florida panther, known for its distinctive characteristics, including a kinked tail and cowlicks, is nearing extinction with the help of scientists and government officials. Though once abundant in Florida, by the end of the twentieth century, only approximately 30 Florida panthers remained. Efforts to preserve the panthers had focused on shielding them from human encroachment with the hope that they could develop sustainable numbers to survive as a species. However, pressure from development caused officials to grow impatient and shift their strategy and goals.
In 1995, new breeds of female panthers were brought to Florida from Texas to bolster the population. The change has been dramatic. In 1990, 88% of the panthers in Florida had the distinct kinked tail. By 2000, five years after the introduction of the Texas panthers, not a single kitten born to the Texas females had a kinked tail. The breed known as the Florida panther is now on an expedited, ineluctable road to extinction
- with the assistance of wildlife protection agencies.
If the goal was to have any kind of panther in Florida, it has been realized. Since the introduction of the Texas panthers, the panther population in Florida has risen to approximately 80 mixed-breed panthers.
However, this "success" could portend a tragic trend in wildlife management in the United States. We cannot and should not create genetically mixed species as a means of achieving a compromise between the needs of development and a species' survival. This type of species tampering is a perversion of the ideal of wildlife management and will irrevocably transform our national landscape.

In the first half of this year, from January to June, about three million videocassette recorders were sold.
This number is only 35 percent of the total number of videocassette recorders sold last year. Therefore, total sales of videocassette recorders will almost certainly be lower for this year than they were for last year.
Which of the following, if true, most seriously weakens the conclusion above?

Nearly a decade ago, researchers at Brandeis University conducted an interesting experiment with small robots. The robots were programmed to get as many individual points as possible by finding small metal pucks and taking them to a nest in a corner of the lab. Robots were rewarded with points whenever they found a puck. But their excessive self-interest led to poor performance as robots repeatedly interfered with one another and battled over pucks. Researchers then reprogrammed the robots to share information:
Robots would announce when they found a puck and listen to what other robots had to say. The robots were able to gather twice as many pucks as they had before they were reprogrammed.
Which of the following conclusions can be drawn from the experiment described in this passage?

The table provides data about 12 different Persian rugs currently available for sale by a rug dealer. For each rug, the data includes the number of knots per square inch (KPSI) in the yarn, which is consistent throughout the rug.
