The oil extracted through these methods is referred to as "green crude" and it's not ready to be used as fuel until it undergoes another process called transesterification. This step adds more substances to the mix, including alcohol and a chemical catalyst that causes the alcohol to react with the oil. This reaction creates a mix of biodiesel and glycerol. The final step in processing separates the glycerol from the mixture and leaves a biodiesel that's ready to be used as fuel. Maybe one day it really will be easy being green.

When there is either a partial or complete tearing on ligaments that are responsible for supporting the joint of the ankle then it causes an ankle sprain.
Based on the exam findings as well as the loss in functionality of the ankle, an ankle sprain can be categorized as grade I, II or III.
In the given situation the 14-year-old girl has a grade II ankle sprain which is characterized by an incomplete tear of the ligaments along with moderate pain (as she rates it 5/10), moderate tenderness, loss of range of some functions, and swelling.
All of the characteristics of the sprain resemble those of the grade II ankle sprain tear and hence, it is characterized as a grade II ankle sprain.
