Problem: Guinea fowl originated in southern Africa, and the species most often kept as poultry is the helmeted guineafowl (Numida meleagris). It is a medium-sized grey or speckled bird with a small naked head with colourful wattles and a knob on top, and was domesticated by the time of the ancient Greeks and Romans. Guinea fowl are hardy, sociable birds that subsist mainly on insects, but also consume grasses and seeds. They will keep a vegetable garden clear of pests and will eat the ticks that carry Lyme disease. They happily roost in trees and give a loud vocal warning of the approach of predators. Their flesh and eggs can be eaten in the same way as chickens, young birds being ready for the table at the age of about four months. 
What continent is the evolution of guinea fowl credited to?
The answer is the following: Africa

Problem: On April 7, 1989, Soviet troops and armored personnel carriers were sent to Tbilisi after more than 100,000 people protested in front of Communist Party headquarters with banners calling for Georgia to secede from the Soviet Union and for Abkhazia to be fully integrated into Georgia. On April 9, 1989, troops attacked the demonstrators; some 20 people were killed and more than 200 wounded. This event radicalized Georgian politics, prompting many to conclude that independence was preferable to continued Soviet rule. On April 14, Gorbachev removed Jumber Patiashvili as First Secretary of the Georgian Communist Party and replaced him with former Georgian KGB chief Givi Gumbaridze.
What did the protesters hope to see become a part of Georgia?
The answer is the following: Abkhazia

Problem: Most Venezuelans have some indigenous heritage, but the indigenous population make up only around 2% of the total population. They speak around 29 different languages and many more dialects, but some of the ethnic groups are very small and their languages are in danger of becoming extinct in the next decades. The most important indigenous groups are the Ye'kuana, the Wayuu, the Pemon and the Warao. The most advanced native people to have lived in present-day Venezuela is thought to have been the Timoto-cuicas, who mainly lived in the Venezuelan Andes. In total it is estimated that there were between 350 thousand and 500 thousand inhabitants, the most densely populated area being the Andean region (Timoto-cuicas), thanks to the advanced agricultural techniques used.
What made the Timoto-cuicas so advanced?
The answer is the following: agricultural techniques used

Problem: Pope Paul VI knew the Roman Curia well, having worked there for a generation from 1922 to 1954. He implemented his reforms in stages, rather than in one fell swoop.

On 28 March, with Pontificalis Domus, and in several additional Apostolic Constitutions in the following years, he revamped the entire Curia, which included reduction of bureaucracy, streamlining of existing congregations and a broader representation of non-Italians in the curial positions.
In what year did Paul VI issue a regulation?
