Explanation:

To solve this matching problem, we analyze each characteristic and its corresponding effect:

1. Match "The land close to the Yellow River was fertile, which means that it could produce many crops. But land farther away from the Yellow River was not." with its effect

• Reason: The fertility of the land near the river explains why people lived close to grow crops (since fertile land supports agriculture).
• Match: "People lived close to the Yellow River so they could grow crops."

2. Match "The Yellow River flooded violently and unpredictably." with its effect

• Reason: Violent, unpredictable flooding would make living near the river dangerous (as floods destroy farms/villages).
• Match: "Living near the Yellow River could be dangerous, because farms and villages could be suddenly destroyed by floods."

3. Match "The Yellow River is filled with fertile yellow soil called loess." with its effect

• Reason: The presence of yellow loess soil in the river explains the river’s yellowish - orange water color.
• Match: "The water in the Yellow River is a yellowish - orange color."

Final Matches:

• Characteristic: "The land close to the Yellow River was fertile, which means that it could produce many crops. But land farther away from the Yellow River was not." → Effect: "People lived close to the Yellow River so they could grow crops."
• Characteristic: "The Yellow River flooded violently and unpredictably." → Effect: "Living near the Yellow River could be dangerous, because farms and villages could be suddenly destroyed by floods."
• Characteristic: "The Yellow River is filled with fertile yellow soil called loess." → Effect: "The water in the Yellow River is a yellowish - orange color."
