Problem: States of Germany:

In 1952, following a referendum, Baden, Wurttemberg-Baden, and Wurttemberg-Hohenzollern merged into Baden-Wurttemberg. In 1957, the Saar Protectorate rejoined the Federal Republic as the Saarland. German reunification in 1990, in which the German Democratic Republic (East Germany) ascended into the Federal Republic, resulted in the addition of the re-established eastern states of Brandenburg, Mecklenburg-West Pomerania (in German Mecklenburg-Vorpommern), Saxony (Sachsen), Saxony-Anhalt (Sachsen-Anhalt), and Thuringia (Thuringen), as well as the reunification of West and East Berlin into Berlin and its establishment as a full and equal state. A regional referendum in 1996 to merge Berlin with surrounding Brandenburg as "Berlin-Brandenburg" failed to reach the necessary majority vote in Brandenburg, while a majority of Berliners voted in favour of the merger.

Problem: War on Terror:

In a major split in the ranks of Al Qaeda's organization, the Iraqi franchise, known as Al Qaeda in Iraq covertly invaded Syria and the Levant and began participating in the ongoing Syrian Civil War, gaining enough support and strength to re-invade Iraq's western provinces under the name of the Islamic State of Iraq and the Levant (ISIS/ISIL), taking over much of the country in a blitzkrieg-like action and combining the Iraq insurgency and Syrian Civil War into a single conflict. Due to their extreme brutality and a complete change in their overall ideology, Al Qaeda's core organization in Central Asia eventually denounced ISIS and directed their affiliates to cut off all ties with this organization. Many analysts[who?] believe that because of this schism, Al Qaeda and ISIL are now in a competition to retain the title of the world's most powerful terrorist organization.

Which civil war did the Iraq branch of Al Qaeda begin fighting in?
---
A: Syrian

Problem: Digestion:

After some time (typically 12 hours in humans, 46 hours in dogs, 34 hours in house cats),[citation needed] the resulting thick liquid is called chyme. When the pyloric sphincter valve opens, chyme enters the duodenum where it mixes with digestive enzymes from the pancreas and bile juice from the liver and then passes through the small intestine, in which digestion continues. When the chyme is fully digested, it is absorbed into the blood. 95% of absorption of nutrients occurs in the small intestine. Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic about 5.6 ~ 6.9. Some vitamins, such as biotin and vitamin K (K2MK7) produced by bacteria in the colon are also absorbed into the blood in the colon. Waste material is eliminated from the rectum during defecation.

What does chyme mix with in the duodenum?
---
A: digestive enzymes from the pancreas and bile juice from the liver
