Extract the answer to the question from the following context. Question: Which building was completed first, the Palais Rohan or the Hotel de Klinglin? Context: The German Renaissance has bequeathed the city some noteworthy buildings (especially the current Chambre de commerce et d'industrie, former town hall, on Place Gutenberg), as did the French Baroque and Classicism with several hotels particuliers (i.e. palaces), among which the Palais Rohan (1742, now housing three museums) is the most spectacular. Other buildings of its kind are the "Hotel de Hanau" (1736, now the city hall), the Hotel de Klinglin (1736, now residence of the prefet), the Hotel des Deux-Ponts (1755, now residence of the military governor), the Hotel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc. The largest baroque building of Strasbourg though is the 150 m (490 ft) long 1720s main building of the Hopital civil. As for French Neo-classicism, it is the Opera House on Place Broglie that most prestigiously represents this style.

Q: Extract the answer to the question from the following context. Question: How was Henry the Young related to Richard in the family? Context: Henry the Young King fought a short war with his brother Richard in 1183 over the status of England, Normandy and Aquitaine. Henry II moved in support of Richard, and Henry the Young King died from dysentery at the end of the campaign. With his primary heir dead, Henry rearranged the plans for the succession: Richard was to be made King of England, albeit without any actual power until the death of his father; Geoffrey would retain Brittany; and John would now become the Duke of Aquitaine in place of Richard. Richard refused to give up Aquitaine; Henry II was furious and ordered John, with help from Geoffrey, to march south and retake the duchy by force. The two attacked the capital of Poitiers, and Richard responded by attacking Brittany. The war ended in stalemate and a tense family reconciliation in England at the end of 1184.
A: brother

Question: Extract the answer to the question from the following context. Question: What happened on the 29th day of the 11th month of the 52nd year of the 20th century? Context: In 1952, the United States elected a new president, and on 29 November 1952, the president-elect, Dwight D. Eisenhower, went to Korea to learn what might end the Korean War. With the United Nations' acceptance of India's proposed Korean War armistice, the KPA, the PVA, and the UN Command ceased fire with the battle line approximately at the 38th parallel. Upon agreeing to the armistice, the belligerents established the Korean Demilitarized Zone (DMZ), which has since been patrolled by the KPA and ROKA, United States, and Joint UN Commands.
Answer: the president-elect, Dwight D. Eisenhower, went to Korea to learn what might end the Korean War

[Q]: Extract the answer to the question from the following context. Question: What do the concentric rings represent? Context: In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.

[A]: each season of growth

Problem: Given the question: Extract the answer to the question from the following context. Question: What is isolated from the bloodstream by the blood-brain barrier? Context: Another approach to brain function is to examine the consequences of damage to specific brain areas. Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the bloodbrain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage. In humans, the effects of strokes and other types of brain damage have been a key source of information about brain function. Because there is no ability to experimentally control the nature of the damage, however, this information is often difficult to interpret. In animal studies, most commonly involving rats, it is possible to use electrodes or locally injected chemicals to produce precise patterns of damage and then examine the consequences for behavior.
