Which of the following statements related to fracking (hydraulic fracturing) is correct?
A.
The fracking process does not increase the efficiency and well productivity.
B.
The fracking process uses very little liquid, and only uses sand.
C.
The most commonly used liquid for fracking is water with a number of chemicals added that are toxic or cancerogenic.
D.
If the fracking liquid is returned to the surface, it is already purified by the soil and does not need further treatment.
E.
Fracking for natural gas is considered a sustainable energy technology due to its high efficiency.

B. Determination of the relative strength of a substance by comparing its effect on a test organism with that of a standard preparation
C. The removal and examination of tissue, cells, or fluids from the living body
D. Having normal biological capability or performance enhanced by or as if by electronic or electromechanical devices

A. adding methanogens to the soil
B. adding nitrifying bacteria to the soil
C. adding denitrifying bacteria to the soil
