Hopefully this hlps you. it took me a long time to find the correct answer in the text book for my early childhood education class
The "healthy young children: a manual for programs" has a section where i found my answer for this exact test question.
The section is found on page 51 in the bottom left corner under "Safety education and hazard checks"
it reads as follows: " Injuries in the environment are a result of unsafe conditions in the enviroment, a mismatch between a child's abilities and activities, and/or a lack of adult supervision"
