Which choice would be least likely to be allowed to function as a natural monopoly in a society's economy? a) food distributionb)  watershed managementc)  electricity generationd)  hazardous waste disposal

First of all, it is necessary to understand the concept of monopoly, which is the event of a single person or enterprise controlling the supply of a particular commodity. Following that logic, a natural monopoly can be understood as a given industry wherein high infrastructural costs and other barriers to entry relative to the size of the market give the largest - usually the first supplier - in the market a virtually overwhelming advantage over competitors.

Therefore, it is possible to affirm that the lesta likely choice to be allowed to function as a natural monopoly in a society economy is food distribution, which can be performed by several different enterprises/individuals.

On the other hand, watershed management, electricity generation and hazardous waste disposal, due to their high cost of capital, creating economies of scale that are large in relation to the size of the market.

the answer is true .

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
