Critical Reasoning: Dialog Format

Mr. Q: More and more people are drinking mineral water. Having a mineral water dispenser in one's home, and having water delivered, will soon become popular since it makes more sense than constantly buying bottles.

Mr. S: I don't think that will happen since having water delivered is far more expensive than buying bottles of water.

Which of the following, if true, most strengthens Mr. Q's claim?

Incorrect.

[[snippet]]

This answer choice weakens Mr. Q's prediction since it provides a reason why consumers may want to stick to buying bottles - they are friendlier to the environment. However, we are looking for a statement that can support Mr. Q's claim that the delivery of mineral water (using dispensers and containers) will become more popular.

Incorrect.

[[snippet]]

This statement neither weakens nor strengthens Mr. Q's claim. The definition of the phrase hard water is irrelevant to the topic at hand. The argument is about whether the delivery of mineral water to homes will increase in popularity. Your task is to look for an answer choice that supports Mr. Q's claim that it will become more popular.

Incorrect.

This answer choice weakens Mr. Q's prediction since it provides a reason why consumers may not want to sign up for the delivery of mineral water. Remember, we are looking for a statement that can support Mr. Q's claim that the delivery of mineral water will become more popular.

Incorrect.

[[snippet]]

This answer choice weakens Mr. Q's prediction. The fact that the cost may be 20% higher for delivered water only provides a reason why consumers may not want to sign up for it. However, we are looking for a statement that can support Mr. Q's claim that the delivery of mineral water will become more popular.

Good stuff!

[[snippet]]

This answer choice provides an excellent reason why consumers would be happy to sign up for delivered water despite the fact that it may cost more than if they were to buy bottled water. In this way, it strengthens Mr. Q's claim that the delivery of mineral water will become more popular.

Water that contains a high amount of minerals per volume is known as hard water.

Signing up to a water delivery service requires that the consumer buy a fairly expensive dispenser from the supplier.
Bottles are easier to recycle than containers for mineral water dispensers.
Having water delivered usually results in the monthly cost of drinking water to be about 20% more expensive than water from other sources.
Many consumers are willing to pay extra in order to avoid the hassle of having to purchase, carry, store, and recycle mineral water bottles.
