Answer:
Ok and...? How's that a question pls what am I doing here I'm just trying to help some kids and this is what I get why.
Answer:
The answer is B: Scientists are confused by the different ways the rocks move, and the theories involving wind, ice, and mud have not been proven.
Explanation:
In the second paragraph, it is said that scientists have been baffled by the variety of rock movement. Then, there was a description of their movement and some possible reasons for why it happens. Some of the reasons(wind, ice and mud) were suggested by scientists. The paragraph then ends by saying that none of the theories have been confirmed by research.
This is conveyed very well by option B therefore it the correct option as the main idea of the paragraph.
If the food is a plant then it could be immature. This means that it hasn't yet ripened to its prime, and it's not very tasty when eaten.
Inedible is another possible word. Inedible things can be non-food items such as a bed (you can not eat a bed therefore it is "inedible") or food items that aren't cooked or prepared where it is safe to eat, such as raw meat.
Hope this helped!
