The young orchestral conductor Sabado Domingo is a true prodigy, able to recognize when any single instrument in his orchestra is even a bit out of tune. In a recent test, an orchestra played a hundred selections from different well-known classical pieces; in approximately half of the selections, exactly one instrument would be played slightly out of tune. In every instance in which an instrument was played out of tune, Domingo pointed out that the orchestra was out of tune, and correctly identified the instrument at fault. Which of the following, if true, most strongly supports the conclusion of the argument above?

Cool Games Corporation derives all of its revenues through the sales of video games. Last year, it fell just short of making a profit although it had strong revenues of $200 million worldwide, half from children and half from adults. This year, the company's sales to children rose 20% to $120 million, but its sales to adults dropped 40% to a disappointing $60 million. One of the most renowned Wall Street analysts had forecasted that Cool Games Corporation would need to at least match its revenues of last year in order to have a chance to make a profit on video games this year. Upon hearing the news of the Cool Games Corporation's revenue, the analyst concluded that it was not possible for the company to have made a profit this year.The analyst's conclusion is based on which of the following assumptions?

The cost of manufacturing automobiles is considerably greater in Esteria than in Burdistan. In order to stimulate Esterian consumers' purchases of domestically manufactured automobiles, the Esterian government has historically charged taxes on automobiles manufactured in Burdistan. Five years ago, however, the Esterian government dropped those taxes; in those five years, the number of workers employed in Esterian automobile factories has decreased by 30%. Therefore, the number of vehicles manufactured and sold in Esteria must have decreased in the last five years.

The single-celled parasite known as Toxoplasma gondii infects more than half of the world's human population without creating any noticeable symptoms. Once inside the human body, Toxoplasma rapidly spreads to the heart and other organs. It can even penetrate the tight barrier that normally protects the brain from most pathogens. Yet, the blood of infected persons carries very few free-floating Toxoplasma cells. Scientists have long been puzzled by this ability of Toxoplasma to parasitize the human body without triggering an immune response and without an appreciable presence in the bloodstream. Recent research, however, has shed light on the ways in which Toxoplasma achieves its remarkable infiltration of the human body.Though there are few individual Toxoplasma cells coursing freely in the blood of an infected person, scientists have discovered that the parasite is quite common in certain cells, known as dendritic cells, involved in the human immune system. Dendritic cells are found in the digestive tract and frequently come into contact with the various pathogens that enter the human body through food and water. When the dendritic cells encounter pathogens, they travel to lymph nodes and relay this information to other immune cells that then take action against the reported pathogen. Scientists have found, however, that Toxoplasma is capable of hijacking dendritic cells, forcing them from their usual activity and using them as a form of transportation to infect the human body quickly. Without this transport mechanism, Toxoplasma could not reach the better-protected areas of the body.Toxoplasma invades the human body through consumption of the undercooked meat of infected animals, primarily pigs and chickens. Other animals, such as cats, can become infected as well. In fact, cats are a necessary component in the reproductive cycle of Toxoplasma, since the animal's intestines are the parasite's sole breeding ground. Toxoplasma creates egg-like cysts, known as oocysts, in the cats' intestines. These oocysts are shed in the cats' droppings and contaminate ground water and soil, eventually finding their way into the food chain. Because Toxoplasma must somehow find its way into a new host cat in order to reproduce, it cannot kill its current host. Instead, it waits for the host, usually a small rodent, to be eaten by a cat, thus providing Toxoplasma the opportunity to reproduce.
