Answer: overextension of words
Explanation:
When children are still around the age of three they may confuse the meaning of words. As a result they may use one word for different things which are not even related maybe because in their still developing mind they see some minor similarities.
For example a car and a bus both have wheels and travel on the road these similarities may cause a child to refer to them both as cars.
If there are these minor similarities that they observe between things, they are likely to use one word to name those things that show similarities.
This occurs because children haven't really grasped the use of langauge, definition of words and all its collect grammar.
Answer:
insufficient strength of the manipulation
Explanation:
The non-significant results may have occurred because of insufficient strength of the manipulation. Since the variable being tested in this scenario had a very slight difference it caused insignificant results. The variable in the study (light bulb) needs to be drastically different in order for it to have an effect on the subjects and provide results that differ. The 100-watt and 125-light bulb provide almost the same luminosity levels.
The answer is B. Economic interdependence
