Input: Consider Input: 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.

Output: Ancient civilizations often alloyed metals for what reason?


Input: Consider Input: The City of Tucson, Pima County, the State of Arizona, and the private sector have all made commitments to create a growing, healthy economy[citation needed] with advanced technology industry sectors as its foundation. Raytheon Missile Systems (formerly Hughes Aircraft Co.), Texas Instruments, IBM, Intuit Inc., Universal Avionics, Honeywell Aerospace, Sunquest Information Systems, Sanofi-Aventis, Ventana Medical Systems, Inc., and Bombardier Aerospace all have a significant presence in Tucson. Roughly 150 Tucson companies are involved in the design and manufacture of optics and optoelectronics systems, earning Tucson the nickname "Optics Valley".

Output: What was Raytheon previously called?


Input: Consider Input: Those who subscribe to this interpretation believe that since the Christian scriptures never counter instrumental language with any negative judgment on instruments, opposition to instruments instead comes from an interpretation of history. There is no written opposition to musical instruments in any setting in the first century and a half of Christian churches (33 AD to 180AD). The use of instruments for Christian worship during this period is also undocumented. Toward the end of the 2nd century, Christians began condemning the instruments themselves. Those who oppose instruments today believe these Church Fathers had a better understanding of God's desire for the church,[citation needed] but there are significant differences between the teachings of these Church Fathers and Christian opposition to instruments today.
Output: What does the rejection of instruments in Christian music likely stem from?
