Humans are naturally compassionate and honest. In a study using strategically placed wallets that appear “lost”, it was found that wallets with money are more likely to be returned than wallets without money. Similarly, wallets that had a key and money are more likely to be returned than wallets with the same amount of money alone. This suggests that the primary reason for this behavior is compassion and empathy. Which one of the following is the CORRECT logical inference based on the information in the above passage?

The correct option is: Wallets with a key are more likely to be returned because people relate to suffering of others.

Step-by-Step Explanation:

1. Analyze the Premise: The passage starts by asserting that humans are naturally compassionate and honest. It then presents evidence from a study: lost wallets containing money are returned more often than those without money. Furthermore, wallets containing both money and a key are even more likely to be returned than wallets containing only money.

2. Examine the Proposed Cause: The passage states that the primary reason driving this behavior is compassion and empathy. A lost key is of no monetary value to the finder, but losing it causes significant distress, inconvenience, and suffering to the owner.

3. Connect the Key to Compassion: Since wallets with a key (in addition to money) are returned at a higher rate, and the passage attributes this behavior to compassion and empathy, it logically follows that the presence of the key triggers a compassionate response. People return the wallet because they empathize with the owner's situation and relate to the potential suffering or trouble the owner would experience from losing their key.

4. Evaluate the Logical Inference: Therefore, the correct logical inference is that wallets with a key are more likely to be returned because people relate to the suffering of others, which directly supports the passage's conclusion about compassion and empathy being the primary drivers.
