Problem: Please answer a question about the following article about Asphalt:
About 40,000,000 tons were produced in 1984[needs update]. It is obtained as the "heavy" (i.e., difficult to distill) fraction. Material with a boiling point greater than around 500 C is considered asphalt. Vacuum distillation separates it from the other components in crude oil (such as naphtha, gasoline and diesel). The resulting material is typically further treated to extract small but valuable amounts of lubricants and to adjust the properties of the material to suit applications. In a de-asphalting unit, the crude asphalt is treated with either propane or butane in a supercritical phase to extract the lighter molecules, which are then separated. Further processing is possible by "blowing" the product: namely reacting it with oxygen. This step makes the product harder and more viscous.
In processing asphalt, what is the unit used to separate it?
A: de-asphalting

In politics, corruption undermines democracy and good governance by flouting or even subverting formal processes. Corruption in elections and in the legislature reduces accountability and distorts representation in policymaking; corruption in the judiciary compromises the rule of law; and corruption in public administration results in the inefficient provision of services. It violates a basic principle of republicanism regarding the centrality of civic virtue.

Political corruption in legislature reduces what, overall?
Answer: accountability

Problem: In several countries, fire safety officials encourage citizens to use the two annual clock shifts as reminders to replace batteries in smoke and carbon monoxide detectors, particularly in autumn, just before the heating and candle season causes an increase in home fires. Similar twice-yearly tasks include reviewing and practicing fire escape and family disaster plans, inspecting vehicle lights, checking storage areas for hazardous materials, reprogramming thermostats, and seasonal vaccinations. Locations without DST can instead use the first days of spring and autumn as reminders.
What should you check storage spaces in your home for twice-yearly?
The answer is the following: hazardous materials

By 1940 the Third Reich had occupied many of the Alpine countries. Austria underwent a political coup that made it part of the Third Reich; France had been invaded and Italy was a fascist regime. Switzerland was the only country to luckily avoid invasion. The Swiss Confederate mobilized its troopsthe country follows the doctrine of "armed neutrality" with all males required to have military traininga number that General Eisenhower estimated to be about 850,000. The Swiss commanders wired the infrastructure leading into the country, and threatening to destroy bridges, railway tunnels and passes in the event of a Nazi invasion, and then they retreated to the heart of the mountain peaks where conditions were harsher and a military invasion would involve difficult and protracted battles.
Who wired the infrastructure leading into Switzerland?
The Swiss commanders
