Problem: The Old Swiss Confederacy had acquired a reputation of invincibility during these earlier wars, but expansion of the federation suffered a setback in 1515 with the Swiss defeat in the Battle of Marignano. This ended the so-called "heroic" epoch of Swiss history. The success of Zwingli's Reformation in some cantons led to inter-cantonal religious conflicts in 1529 and 1531 (Wars of Kappel). It was not until more than one hundred years after these internal wars that, in 1648, under the Peace of Westphalia, European countries recognized Switzerland's independence from the Holy Roman Empire and its neutrality.
In what two years were the Wars of Kappel?
The answer is the following: 1529 and 1531

Problem: In addition to the use of sound for communication, a wide range of insects have evolved chemical means for communication. These chemicals, termed semiochemicals, are often derived from plant metabolites include those meant to attract, repel and provide other kinds of information. Pheromones, a type of semiochemical, are used for attracting mates of the opposite sex, for aggregating conspecific individuals of both sexes, for deterring other individuals from approaching, to mark a trail, and to trigger aggression in nearby individuals. Allomonea benefit their producer by the effect they have upon the receiver. Kairomones benefit their receiver instead of their producer. Synomones benefit the producer and the receiver. While some chemicals are targeted at individuals of the same species, others are used for communication across species. The use of scents is especially well known to have developed in social insects.:96–105
What insect chemical benefits both the receiver and the producer?
The answer is the following: Synomones

Problem: The constitution of the Fifth Republic states that French alone is the official language of the Republic. However, Alsatian, along with other regional languages, are recognized by the French government in the official list of languages of France. A 1999 INSEE survey counted 548,000 adult speakers of Alsatian in France, making it the second most-spoken regional language in the country (after Occitan). Like all regional languages in France, however, the transmission of Alsatian is on the decline. While 39% of the adult population of Alsace speaks Alsatian, only one in four children speaks it, and only one in ten children uses it regularly.
How many adult speakers speak Alsatian according the 1999 INSEE survey?
The answer is the following: 548,000

Problem: Some skyscraper buildings and other types of installation feature a destination operating panel where a passenger registers their floor calls before entering the car. The system lets them know which car to wait for, instead of everyone boarding the next car. In this way, travel time is reduced as the elevator makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Although travel time is reduced, passenger waiting times may be longer as they will not necessarily be allocated the next car to depart. During the down peak period the benefit of destination control will be limited as passengers have a common destination.
What is one benefit of a "destination operating panel"
The answer is the following:
travel time is reduced as the elevator makes fewer stops for individual passengers
