$19.$ Which of the following factors is responsible for enabling the advance of Moore$$s Law?

a$.$ The distance between pathways inside silicon chips gets smaller with each successive generation.

b$.$ Silicon is commonly available in the form of sand or silicon dioxide, which helps keep the costs of chip production low.

c$.$ Constant interaction among three forces$$size$,$ heat, and power$$makes Moore$$s Law practical and ensures that it will endure for decades to come.

d$.$ The availability of better cooling technologies ensures chips can continue growing smaller and more power efficient.

e$.$ With the exponential growth in information technology$-$enabled businesses, the demand for computers makes Moore$$s Law possible.
