Problem: Nintendo Entertainment System:

Nintendo was accused of antitrust behavior because of the strict licensing requirements. The United States Department of Justice and several states began probing Nintendo's business practices, leading to the involvement of Congress and the Federal Trade Commission (FTC). The FTC conducted an extensive investigation which included interviewing hundreds of retailers. During the FTC probe, Nintendo changed the terms of its publisher licensing agreements to eliminate the two-year rule and other restrictive terms. Nintendo and the FTC settled the case in April 1991, with Nintendo required to send vouchers giving a $5 discount off to a new game, to every person that had purchased a NES title between June 1988 and December 1990. GameSpy remarked that Nintendo's punishment was particularly weak giving the case's findings, although it has been speculated that the FTC did not want to damage the video game industry in the United States.

Problem: Glass:

Glass was used extensively during the Middle Ages. Anglo-Saxon glass has been found across England during archaeological excavations of both settlement and cemetery sites. Glass in the Anglo-Saxon period was used in the manufacture of a range of objects including vessels, beads, windows and was also used in jewelry. From the 10th-century onwards, glass was employed in stained glass windows of churches and cathedrals, with famous examples at Chartres Cathedral and the Basilica of Saint Denis. By the 14th-century, architects were designing buildings with walls of stained glass such as Sainte-Chapelle, Paris, (1203–1248) and the East end of Gloucester Cathedral. Stained glass had a major revival with Gothic Revival architecture in the 19th-century. With the Renaissance, and a change in architectural style, the use of large stained glass windows became less prevalent. The use of domestic stained glass increased until most substantial houses had glass windows. These were initially small panes leaded together, but with the changes in technology, glass could be manufactured relatively cheaply in increasingly larger sheets. This led to larger window panes, and, in the 20th-century, to much larger windows in ordinary domestic and commercial buildings.

What did technological changes allow regular homes to have?
---
A: larger windows

What is the French name of the Canadian Armed Forces?

Problem: Predation:

Mimicry is a related phenomenon where an organism has a similar appearance to another species. One such example is the drone fly, which looks a lot like a bee, yet is completely harmless as it cannot sting at all. Another example of batesian mimicry is the io moth, (Automeris io), which has markings on its wings that resemble an owl's eyes. When an insectivorous predator disturbs the moth, it reveals its hind wings, temporarily startling the predator and giving it time to escape. Predators may also use mimicry to lure their prey, however. Female fireflies of the genus Photuris, for example, copy the light signals of other species, thereby attracting male fireflies, which are then captured and eaten (see aggressive mimicry).

What happens when drone flies attract male fireflies?
