Explanation:

Identify the question and options

The image shows a multiple-choice question: "Thermometer should be placed".
The visible options are:

1. "Near doors"
2. "Top of shelf"

Analyze thermometer placement principles

In a laboratory, pharmacy, or storage environment, thermometers must be placed to measure the representative temperature of the area or equipment.

• Placing a thermometer near doors is incorrect because drafts and external air exchange when doors open cause highly fluctuating and unrepresentative temperature readings.
• Placing a thermometer on the top of a shelf is also generally avoided because warm air rises, which can lead to higher temperature readings than the average room or storage temperature. However, in standard storage monitoring protocols (such as vaccine or medication storage), thermometers should be placed in the middle of the shelf/compartment, away from the doors, walls, and direct cooling/heating vents to get an accurate, stable reading.
• Between the two visible options, "Near doors" is highly unstable due to constant drafts. "Top of shelf" (or middle of the shelf in standard guidelines) represents a more stable location than near a drafty door. Let's evaluate standard safety/storage guidelines: thermometers monitoring room or refrigerator temperature should never be placed near doors. Thus, "Near doors" is incorrect, making "Top of shelf" the better choice among the two.

Formulate the final selection

We select "Top of shelf" as the correct option because placing a thermometer near doors leads to inaccurate readings due to external drafts.

Answer:

• Near doors
• Top of shelf (Correct answer)
