Problem: It has been observed that well-fed predator animals in a lax captivity (for instance, pet or farm animals) will usually differentiate between putative prey animals who are familiar co-inhabitants in the same human area from wild ones outside the area. This interaction can range from peaceful coexistence to close companionship; motivation to ignore the predatory instinct may result from mutual advantage or fear of reprisal from human masters who have made clear that harming co-inhabitants will not be tolerated. Pet cats and pet mice, for example, may live together in the same human residence without incident as companions. Pet cats and pet dogs under human mastership often depend on each other for warmth, companionship, and even protection, particularly in rural areas.
Well-fed animals in captivity can become friends with prey animals due to what motivation?
The answer is the following: mutual advantage or fear of reprisal from human masters

Problem: Many ancient civilizations alloyed metals for purely aesthetic purposes. In ancient Egypt and Mycenae, gold was often alloyed with copper to produce red-gold, or iron to produce a bright burgundy-gold. Gold was often found alloyed with silver or other metals to produce various types of colored gold. These metals were also used to strengthen each other, for more practical purposes. Copper was often added to silver to make sterling silver, increasing its strength for use in dishes, silverware, and other practical items. Quite often, precious metals were alloyed with less valuable substances as a means to deceive buyers. Around 250 BC, Archimedes was commissioned by the king to find a way to check the purity of the gold in a crown, leading to the famous bath-house shouting of "Eureka!" upon the discovery of Archimedes' principle.
Red gold is made by combining gold with?
The answer is the following: copper

Problem: Switzerland's most important economic sector is manufacturing. Manufacturing consists largely of the production of specialist chemicals, health and pharmaceutical goods, scientific and precision measuring instruments and musical instruments. The largest exported goods are chemicals (34% of exported goods), machines/electronics (20.9%), and precision instruments/watches (16.9%). Exported services amount to a third of exports. The service sector especially banking and insurance, tourism, and international organisations is another important industry for Switzerland.
What accounts for 34% of Switzerland's exported goods?
The answer is the following: chemicals

Problem: Weeks after ending the Sex Pistols, Lydon formed the experimental group Public Image Ltd and declared the project to be "anti music of any kind". Public Image and other acts such as the Pop Group and the Slits had begun experimenting with dance music, dub production techniques and the avant-garde, while punk-indebted Manchester acts such as Joy Division, The Fall and A Certain Ratio developed unique styles which drew on a similarly disparate range of influences across music and modernist literature. Bands such as Scritti Politti, Gang of Four and This Heat incorporated Leftist political philosophy and their own art school studies in their work.
What group declared itself to be anti-music of any kind?
The answer is the following:
Public Image Ltd
