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?
- Wallets with a key are more likely to be returned because people do not care about money
- Wallets with a key are more likely to be returned because people relate to suffering of others
- Wallets used in experiments are more likely to be returned than wallets that are really lost
- Money is always more important than keys
