Consumer: The latest Connorly Report suggests that Ocksenfrey prepackaged meals are virtually devoid of nutritional value. But the Connorly Report is commissioned by Danto Foods, Ocksenfrey’s largest corporate rival, and early drafts of the report are submitted for approval to Danto Foods’ public relations department. Because of the obvious bias of this report, it is clear that Ocksenfrey’s prepackaged meals really are nutritious.
The reasoning in the consumer’s argument is most vulnerable to criticism on the grounds that the argument
- fails to take into account the possibility that Ocksenfrey has just as much motivation to create negative publicity for Danto as Danto has to create negative publicity for Ocksenfrey
- treats evidence that there is an apparent bias as evidence that the Connorly Report’s claims are false
- draws a conclusion based solely on an unrepresentative sample of Ocksenfrey’s products
- presumes, without providing justification, that Danto Foods’ public relations department would not approve a draft of a report that was hostile to Danto Foods’ products
- fails to provide evidence that Danto Foods’ prepackaged meals are not more nutritious than Ocksenfrey’s are

Scientist: Earth’s average annual temperature has increased by about 0.5 degrees Celsius over the last century. This warming is primarily the result of the buildup of minor gases in the atmosphere, blocking the outward flow of heat from the planet.
Which one of the following, if true, would count as evidence against the scientist’s explanation of Earth’s warming?
- Most of the warming occurred before 1940, while most of the buildup of minor gases in the atmosphere occurred after 1940.
- Volcanic dust and other particles in the atmosphere reflect much of the Sun’s radiation back into space before it can reach Earth’s surface
- The accumulation of minor gases in the atmosphere has been greater over the last century than at any other time in Earth’s history.
- Only some of the minor gases whose presence in the atmosphere allegedly resulted in the phenomenon described by the scientist were produced by industrial pollution.
- Over the last century, Earth received slightly more solar radiation in certain years than it did in others.

You are a prisoner sentenced to death. The Emperor offers you a chance to live by playing a simple game. He gives you 50 black marbles, 50 white marbles and 2 empty bowls. He then says, "Divide these 100 marbles into these 2 bowls. You can divide them any way you like as long as you use all the marbles. Then I will blindfold you and mix the bowls around. You then can choose one bowl and remove ONE marble. If the marble is WHITE you will live, but if the marble is BLACK... you will die."
How do you divide the marbles up so that you have the greatest probability of choosing a WHITE marble
