INSTRUCTIONS: The following problems relate to identifying and evaluating inductive and deductive arguments. Select the best answer for each.After smoking only a few cigarettes per day, Krista became addicted within two months. The same thing happened to Dave, Jean, and Marty.

INSTRUCTIONS: A) Fill out a truth table for the following statement, and then B) state whether the statement is tautologous, self-contradictory, or contingent. Be sure to identify the main operator and show all of your work. (P  ⊃  ∼ B)  ∨  (B  ⊃  ∼ L) You may copy the first row of a table from here: (P ⊃ ~ B) ∨ (B ⊃ ~ L)

​ ​ INSTRUCTIONS: The following selections relate to distinguishing arguments from nonarguments and identifying conclusions. Select the best answer for each. The world-wide disappearance of frogs may be the result of agricultural runoff. Scientists have shown that runoff rich in fertilizer causes a pronounced increase in the algae of lakes and ponds. Snails then gorge themselves on the algae, causing parasites living inside them to produce huge quantities of eggs. When the eggs hatch, the parasites infect young frogs, causing severe deformation of their limbs.

INSTRUCTIONS: The following problems relate to identifying and evaluating inductive and deductive arguments. Select the best answer for each.As climate change continues, the temperature of the world’s oceans will rise. As ocean temperatures rise, hurricanes will become more intense. Therefore, hurricanes in the Caribbean will intensify in the years ahead.

INSTRUCTIONS: The following problems relate to identifying and evaluating inductive and deductive arguments. Select the best answer for each.As the universe expands, it gets colder and colder. Furthermore, this expansion will continue for ever and ever. Therefore, at some point in the future the universe will become too cold to support human life, and all humans will perish.

INSTRUCTIONS: The following problems relate to identifying and evaluating inductive and deductive arguments.

​ ​ INSTRUCTIONS: The following selections relate to distinguishing arguments from nonarguments and identifying conclusions. Select the best answer for each.While there is no technology to reduce CO2 from a car’s exhaust, we can make cars pollute less by making them more fuel efficient. By using today’s best technology, car makers could dramatically increase the fuel economy of their cars and trucks. In fact, off-the-shelf technology can change the nation’s best selling SUV, the Ford Explorer, from a 19 mpg gas guzzler to an efficient 34 mpg vehicle. If we are to make any progress in slowing global warming, we must make our cars go farther on a gallon of gas. Sierra Club, “Global Warming Solutions”
