Critical Reasoning: Dialog Format

Jennifer: Despite the promotional campaigns, it seems that not many people are actually recycling waste materials.

Marco: I disagree. The recycling station near my home is always very busy with people bringing in various objects for recycling.

Which of the following, if true, most strengthens Marco's objection to Jennifer's claim?

Incorrect.

[[snippet]]

This answer choice weakens Marco's claim. If each station covers a large area with many people, then even if a small percentage of people recycle, the station will seem busy.

Incorrect.

[[snippet]]

This answer choice strengthens Jennifer's claim and, therefore, weakens Marco's. If promotional campaigns for recycling have low success rates, then Jennifer's observation that people are still not recycling despite the campaign seems more likely. We should be looking for a statement that shows that Jennifer's claim is not true.

Incorrect.

[[snippet]]

This answer choice neither strengthens nor weakens Marco's objection. The argument between Marco and Jennifer has nothing to do with the merits of recycling, but instead is about whether people are actively recycling. Therefore. this statement is irrelevant to the topic.

Incorrect.

[[snippet]]

This answer choice strengthens Jennifer's claim and, therefore, weakens Marco's. If promotional campaigns for recycling are often ineffective, then we are led to believe that the campaign may not have caused more people to recycle, and that Marco is wrong. However, we should be looking for a statement that supports Marco's viewpoint.

Nice work!

[[snippet]]

This answer choice gives support to Marco's claim. If factories are receiving more recycled materials, then more people must be actively recycling.

Each recycling station is responsible for collecting the waste materials of a very large area inhabited by many citizens.
In some countries, recycling managed to significantly reduce pollution in a period of only several years.
A recent survey shows that promotional campaigns for recycling have the lowest success rate of any advertising campaign.
Factories that use recyclable substances have reported significant rises in profits due to an increase in the supply of recycled materials.
It has been noted that many promotional campaigns for recycling are ineffective as people report that they feel that they are being preached to.
