premise: How to refrigerate foods safely<br>Avoid packing your refrigerator tightly. Packing loosely allows the cold air to circulate. Use an appliance thermometer to monitor the real temperature inside your refrigerator and your freezer.
hypothesis: The article advises not to place too many food items in the refrigerator.
reason: It's definitely correct because it says to avoid packing the refrigerator tightly, which means to leave space between the food, hence you must not put too much food in the refrigerator. It's difficult because this is not stated explicitly and requires a high level understanding of the text.
