Critical Reasoning: Dialog Format

Juan: Gas stoves are cheaper to run than electric stoves since propane, the flammable gas they burn, is inexpensive and readily available in cylinders. We should buy a gas stove for our new home.

Jeanette: Electric stoves are safer especially because the climate where we live contributes to the development of corrosion which can lead to small cracks in the pipes and to subsequent leakage of the gas. I'd prefer it if we bought an electric stove.

Which of the following, if true, most strengthens Jeanette's objection to Juan's proposition?

Incorrect.

[[snippet]]

This answer choice neither strengthens nor weakens Jeanette's objection. The dilemma presented in the argument is between gas and electric stoves. This statement, however, compares online vendors to brick-and-mortar stores. This comparison is irrelevant.

Look for an answer choice which relates directly to the reasons presented by either Juan or Jeanette.

Incorrect.

[[snippet]]

This answer choice neither strengthens nor weakens Jeanette's objection. Because this statement provides information that applies to both gas and electric stoves, it cannot help us show that Jeanette's preference for electric stoves is valid.

Incorrect.

[[snippet]]

This answer choice weakens Jeanette's objection. By stating that electric stoves are more expensive than gas stoves, we are directly supporting Juan's position while we are supposed to be weakening it (or supporting Jeanette's).

Incorrect.

[[snippet]]

This answer choice weakens Jeanette's objection.The fact that electric stoves do not offer dynamic control while gas stoves do lowers our appreciation of electric stoves and heightens that of gas stoves. However, to support Jeanette's position, we should be looking for a statement that is in favor of electric stoves.

You've got it!

[[snippet]]

This statement provides us with two reasons for why propane is dangerous: it is poisonous and highly flammable. Therefore, it directly strengthens Jeanette's objection to buy a gas stove.

Hydrocarbons, the chemical group in which propane is a member, are considered dangerous since they are both poisonous and highly flammable.
Electric stoves are, on average, more expensive to buy than gas stoves since they are installed with more sophisticated electronic circuitry.
Gas and electric stoves are usually fitted with surfaces that have been coated with a thick layer of enamel to allow them to be easily cleaned.
Electric stoves do not offer dynamic control of the heat source in the same way that gas stoves do.
Recent statistics show that online vendors sell a higher number of electric stoves than brick-and-mortar stores.
