Answer :
Sure, let's work through this step by step to find the upper temperature at which our sensitivity to different tastes is greatest, given that one of the temperature limits is 71 degrees Fahrenheit.
### Steps to determine the upper temperature limit:
1. Understanding Sensitivity to Taste and Temperature:
- Typically, our taste sensitivity is influenced by the temperature of the food. There's a specific range where our taste buds are most active and sensitive.
2. Given Range:
- We know the lower temperature limit is 71 degrees Fahrenheit.
3. Options to Consider:
- The possible upper limits given in the choices are:
- 100 degrees Fahrenheit
- 78 degrees Fahrenheit
- 92 degrees Fahrenheit
- 89 degrees Fahrenheit
4. Determining the Correct Upper Limit:
- Considering the common understanding of how taste sensitivity works, between these options, the temperature that best matches the common taste sensitivity range would be 89 degrees Fahrenheit.
### Conclusion:
- Our sensitivity to different tastes is greatest when the food is between the temperatures of 71 degrees Fahrenheit and 89 degrees Fahrenheit.
So, the correct choice is 89 degrees Fahrenheit.
