Problem: Please answer a question about the following article about Buckingham Palace:
During World War II, the palace was bombed nine times, the most serious and publicised of which resulted in the destruction of the palace chapel in 1940. Coverage of this event was played in cinemas all over the UK to show the common suffering of rich and poor. One bomb fell in the palace quadrangle while King George VI and Queen Elizabeth were in residence, and many windows were blown in and the chapel destroyed. War-time coverage of such incidents was severely restricted, however. The King and Queen were filmed inspecting their bombed home, the smiling Queen, as always, immaculately dressed in a hat and matching coat seemingly unbothered by the damage around her. It was at this time the Queen famously declared: "I'm glad we have been bombed. Now I can look the East End in the face". The royal family were seen as sharing their subjects' hardship, as The Sunday Graphic reported:
Which monarchs were in residence at Buckingham Palace during WWII?

The world's largest deposit of natural bitumen, known as the Athabasca oil sands is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies attribute the oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands, to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta bitumen deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage.

How old are the Athabasca deposits?
Answer: 110 million years

Problem: President Benito Juarez was re-elected in the general election of 1867 in which he received strong liberal support, especially in Chihuahua. Luis Terrazas was confirmed by the people of Chihuahua to be governor of the state. But soon after the election, President Juarez had another crisis on his hands; the Juarez administration was suspected to be involved in the assassination of the military chief Jose Maria Patoni executed by General Canto in August 1868. General Canto turned himself over to Donato Guerra. Canto was sentenced to death, but later his sentence changed to 10 years imprisonment. The sense of injustice gave rise to a new rebellion in 1869 that threatened the federal government. In response, the Juarez administration took drastic measures by temporarily suspending constitutional rights, but the governor of Chihuahua did not support this action. Hostilities continued to increase especially after the election of 1871 which was perceived to be fraudulent. A new popular leader arose among the rebels, Porfirio Diaz. The federal government was successful in quelling rebellions in Durango an Chihuahua. On July 18, 1872, President Juarez died from a heart attack; soon after, many of his supporters ceased the fighting. Peace returned to Chihuahua and the new government was led by Governor Antonio Ochoa (formerly a co-owner of the Batopilas silver mines) in 1873 after Luis Terrazas finished his term in 1872.
Benito Juarez was reelected in which year?
The answer is the following: 1867

The note met with the approval of Nicholas I; however, Abdulmecid I rejected the proposal, feeling that the document's poor phrasing left it open to many different interpretations. The United Kingdom, France, and Austria united in proposing amendments to mollify the Sultan, but the court of St. Petersburg ignored their suggestions.:143 The UK and France then set aside the idea of continuing negotiations, but Austria and Prussia did not believe that the rejection of the proposed amendments justified the abandonment of the diplomatic process.

Problem: Please answer a question about the following article about Digestion:
The abomasum is the fourth and final stomach compartment in ruminants. It is a close equivalent of a monogastric stomach (e.g., those in humans or pigs), and digesta is processed here in much the same way. It serves primarily as a site for acid hydrolysis of microbial and dietary protein, preparing these protein sources for further digestion and absorption in the small intestine. Digesta is finally moved into the small intestine, where the digestion and absorption of nutrients occurs. Microbes produced in the reticulo-rumen are also digested in the small intestine.
What is the fourth and final stomach compartment in ruminants?
A:
The abomasum
