**Question:**
Students measure changes in the temperature of lake water with a temperature probe. The probe is connected to a computer inside the classroom. Which of these best describes an advantage of having the temperature probe connected to a computer?

**Choices:**
- The computer can automatically display the temperature data in a graph.
- The computer can choose the best location to place the probe.
- The computer can randomly correct errors in the data collected by the probe.
- The computer can determine the cause of a temperature change.

**Explanation of Choices:**

1. **The computer can automatically display the temperature data in a graph.**
   This choice highlights a significant advantage of having the temperature probe connected to a computer. Computers can log temperature readings in real-time and display this data graphically, allowing for easy analysis of trends and patterns over time.

2. **The computer can choose the best location to place the probe.**
   This choice is incorrect as determining the best location to place the probe typically requires human judgment and consideration of the environment, not something a computer can decide autonomously with current technology.

3. **The computer can randomly correct errors in the data collected by the probe.**
   This choice is misleading. While computers can perform data validation and filtering, they do not randomly correct errors, as this would introduce more inaccuracies. Error correction typically requires a systematic approach based on predefined criteria.

4. **The computer can determine the cause of a temperature change.**
   This choice is also incorrect. While computers can help analyze data and identify correlations, determining the cause of a temperature change often requires additional information and understanding of environmental factors, which may involve human expertise.
