Problem: Muammar Gaddafi:

In mid-1969, Idris travelled abroad to spend the summer in Turkey and Greece. Gaddafi's Free Officers recognized this as their chance to overthrow the monarchy, initiating "Operation Jerusalem". On 1 September, they occupied airports, police depots, radio stations and government offices in Tripoli and Benghazi. Gaddafi took control of the Berka barracks in Benghazi, while Omar Meheisha occupied Tripoli barracks and Jalloud seized the city's anti-aircraft batteries. Khweldi Hameidi was sent to arrest crown prince Sayyid Hasan ar-Rida al-Mahdi as-Sanussi, and force him to relinquish his claim to the throne. They met no serious resistance, and wielded little violence against the monarchists.

What did Hameidi do during the coup?

A: Hameidi was sent to arrest crown prince Sayyid Hasan ar-Rida al-Mahdi as-Sanussi, and force him to relinquish his claim to the throne.

Problem: Great Plains:

With the arrival of Francisco Vazquez de Coronado, a Spanish conquistador, the first recorded history of encounter between Europeans and Native Americans in the Great Plains occurred in Texas, Kansas and Nebraska from 1540-1542. In that same time period, Hernando de Soto crossed a west-northwest direction in what is now Oklahoma and Texas. Today this is known as the De Soto Trail. The Spanish thought the Great Plains were the location of the mythological Quivira and Cibola, a place said to be rich in gold.

In what state did Francisco Vazquez de Coronado first encounter Native Americans?

A: unanswerable

Problem: Race (human categorization):

Patterns such as those seen in human physical and genetic variation as described above, have led to the consequence that the number and geographic location of any described races is highly dependent on the importance attributed to, and quantity of, the traits considered. Scientists discovered a skin-lighting mutation that partially accounts for the appearance of Light skin in humans (people who migrated out of Africa northward into what is now Europe) which they estimate occurred 20,000 to 50,000 years ago. The East Asians owe their relatively light skin to different mutations. On the other hand, the greater the number of traits (or alleles) considered, the more subdivisions of humanity are detected, since traits and gene frequencies do not always correspond to the same geographical location. Or as Ossorio & Duster (2005) put it:

What is the consequence of the number and geographic location ascribed to a race highly dependent on?
---
A: the importance attributed to, and quantity of, the traits considered.

Problem: A cappella:

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.

Whose teachings are in line with today's opposition to instruments?

A:
unanswerable
