Input: Wood
New domestic housing in many parts of the world today is commonly made from timber-framed construction. Engineered wood products are becoming a bigger part of the construction industry. They may be used in both residential and commercial buildings as structural and aesthetic materials.

In addition to residential applications, what type of buildings often have engineered wood components?
Output: commercial

Input: Westminster Abbey
On Saturday September 6, 1997 the formal, though not "state" Funeral of Diana, Princess of Wales, was held. It was a royal ceremonial funeral including royal pageantry and Anglican funeral liturgy. A Second Public service was held on Sunday at the demand of the people. The burial occurred privately later the same day. Diana's former husband, sons, mother, siblings, a close friend, and a clergyman were present. Diana's body was clothed in a black long-sleeved dress designed by Catherine Walker, which she had chosen some weeks before. A set of rosary beads was placed in her hands, a gift she had received from Mother Teresa. Her grave is on the grounds of her family estate, Althorp, on a private island.[citation needed]

Who gave Diana the rosary beads?
Output: Mother Teresa

Input: Middle Ages
Popes called for crusades to take place elsewhere besides the Holy Land: in Spain, southern France, and along the Baltic. The Spanish crusades became fused with the Reconquista of Spain from the Muslims. Although the Templars and Hospitallers took part in the Spanish crusades, similar Spanish military religious orders were founded, most of which had become part of the two main orders of Calatrava and Santiago by the beginning of the 12th century. Northern Europe also remained outside Christian influence until the 11th century or later, and became a crusading venue as part of the Northern Crusades of the 12th to 14th centuries. These crusades also spawned a military order, the Order of the Sword Brothers. Another order, the Teutonic Knights, although originally founded in the crusader states, focused much of its activity in the Baltic after 1225, and in 1309 moved its headquarters to Marienburg in Prussia.

What century saw the end of the Northern Crusades?
Output: 14th

Input: Incandescent light bulb
One of the problems of the standard electric light bulb is filament notching due to evaporation of the filament. Small variations in resistivity along the filament cause "hot spots" to form at points of higher resistivity; a variation of diameter of only 1% will cause a 25% reduction in service life. These hot spots evaporate faster than the rest of the filament, which increases the resistance at that point—this creates a positive feedback that ends in the familiar tiny gap in an otherwise healthy-looking filament. Irving Langmuir found that an inert gas, instead of vacuum, would retard evaporation. General service incandescent light bulbs over about 25 watts in rating are now filled with a mixture of mostly argon and some nitrogen, or sometimes krypton. Lamps operated on direct current develop random stairstep irregularities on the filament surface which may cut lifespan in half compared to AC operation; different alloys of tungsten and rhenium can be used to counteract the effect.

Which type of alloys can decrease "stairstep" irregularities in light bulb filaments?
Output:
alloys of tungsten and rhenium
