Any practices should best be based on a research - this is the correct answer. (a. child development and research) Research is the best source of actual knowledge, rather than people's best guesses (people's best guesses might lead government regulations, but it would be better if they also followed research results.).
The ant is 0.125 inches long. (1/8= 0.125)
The ant is 0.3175 centimeters long (there are 2.54 centimeters in an inch so 2.54x0.125= 0.3175)
