Answer:
The Interstate Highway System was launched when President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956. Its purpose was to provide high-speed, high-capacity system of highways without stoplights and with exits spaced, whenever possible, at least a mile apart.
The interstate highway system has had a profound effect upon the American economy and contributed significantly to improved economic efficiency and productivity. By increasing speed and expanding access, freight costs have been reduced substantially.
They were intended to serve several purposes: eliminate traffic congestion; replace what one highway advocate called “undesirable slum areas” with pristine ribbons of concrete; make coast-to-coast transportation more efficient; and make it easy to get out of big cities in case of an atomic attack.May 27, 2010

There in an increase in reactivity because the nonmetals want to hold on to their electrons.
<h3>Reactivity</h3>
With less electronegativity, there is also less ionization energy. For metals, it is easier to lose the electrons, hence the metal becomes more reactive because it uses less energy.
For nonmetals, they are gain electrons and not lose them. Thus, an increase in electronegativity and ionization energy means an increase in reactivity because the nonmetals want to hold on to their electrons.
