Final answer:
For a digital thermometer, insert the bottom section in the middle, but closer to the base, into the center of the food to get an accurate temperature reading. The correct option is D.
Step-by-step explanation:
For a digital thermometer, the bottom d. in the middle, but generally closer to the base of the stem must be inserted into the center of the food. When using a thermometer to ensure that food is cooked to a safe temperature, it is crucial to insert it properly so that an accurate reading can be obtained.
The thermometer should be placed in the thickest part of the food, or if it is a liquid, below the surface, to ensure that it measures the temperature of the food itself, rather than the ambient temperature.
This concept of measurement accuracy is consistent with best practices in other forms of temperature and volume measurement, including reading the meniscus at eye level in a graduated cylinder and using a standard thermometer to ensure standardized temperature readings across different instruments.
