Explanation:
This is because electrons requires energy to get excited. The energy required is very high. Thus insulators do not conduct electricity or insulators are insulators because of very large energy band gap between the valence band and conduction band.
According to Eysenck, extraverts have a reticular activating system that is <u>tight</u>, and introverts have an <u>open</u> reticular activating system.
Explanation:
Hans Jurgen Eysenck, a German-born British psychologist, is well-known for his developments in the field of personality and intelligence within the domain of psychology.
As a part of his biological trait theory, he spoke about extraversion and introversion - the former referring to individuals who are extremely expressive and outgoing, while the latter referring to those who are relatively more shy, quiet or reserved in nature.
According to him, the reticular activating system is responsible for controlling the quantities of sensory inputs in the brain. In introverts, this system is wide open (hence introverts tend to avoid any extra stimulation). However, in extraverts, this system can be seen to be somewhat tighter, making them insensitive (and hence craving extra stimulation).
The correct answer is; Plank.
Further Explanation:
North Carolina started building plank roads in the late 1840's. These roads were easier to maintain and easier to drive on. Before the plank roads were built, the roads had long muddy roads and large holes and ruts that drivers had to navigate through.
The crews could only lay an estimated 40 miles of plank roads per year and this did cause issues. North Carolina had the largest plank road with a total of 500 miles built. The rods failed after a few years because it took so long to build.
Citizens were then using the railroad system since it was faster than traveling by horse and buggy. The people also did not like having to stop at the toll booth that had been set up on the road. The money collected at the toll booth was used to pay for maintenance of the plank road.
