The answer to this is B. anthracite coal. Organic matter gradually turns into coal over many years of high pressure and temperature under the earth. The lowest form of coal is peat (where it is still recognizably plant matter), followed by lignite, then sub-bituminous coal, then bituminous coal, then anthracite. These are also ordered from lowest to highest composition of carbon.

if you practice a musical instrument each day for 2/3 of an hour how many hours of practice would you get in each week?
RideAnS [48]
In order to find the answer of the given problem above, we need to make the solution below:
Given: 2/3 of an hour = practice each day
           2/3 of an hour is equivalent to 40 minutes
And per week, there are 7 days. So we will multiply 40 minutes by 7, and the result is 280 minutes. Since there are 60 minutes in an hour, we divide 280 by 60 and we get 4.67 hours. Therefore, each week, you would get 4.67 hours of practice on playing a  musical instrument.
