The answer would be A, slash and burn.
It sounds like conglomerate rock, which is made of other pieces of rock stuck together.
Answer:
Centre of Gravity
The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.
Centre of Gravity in the Human Body
In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.
The overall goal of IPM is to reduce the environmental and health risks of pesticides within social and economic constraints.
Fix: The scope of IPM implementation will continue to change greatly in the future. What began as limited approaches to promote integration of control methods for key pests and provide guidelines for decisions regarding pesticide applications is evolving to an ecologically-based systems approach.
