Which of the following is NOT one of the seven tips for maintaining a healthy home?

The choice "keep it misplaced" is the correct answer because it directly contradicts the principles of maintaining a healthy home. The seven tips for maintaining a healthy home typically emphasize organization, cleanliness, and proper management of the living environment. Misplacing items can lead to clutter, increased stress, and potential hazards, which detracts from the overall healthiness of the home.

On the other hand, keeping a home clean, well-ventilated, and pest-free are all fundamental aspects of promoting health and safety in residential environments. Cleanliness reduces the risk of allergens and pathogens, good ventilation enhances air quality and comfort, and maintaining a pest-free environment prevents infestations that could lead to health issues. Thus, emphasizing the importance of a well-organized and adequately maintained space enhances the overall well-being of the occupants.
