Problem: Please answer a question about the following article about Wood:
Certain types of musical instruments, such as those of the violin family, the guitar, the clarinet and recorder, the xylophone, and the marimba, are traditionally made mostly or entirely of wood. The choice of wood may make a significant difference to the tone and resonant qualities of the instrument, and tonewoods have widely differing properties, ranging from the hard and dense african blackwood (used for the bodies of clarinets) to the light but resonant European spruce (Picea abies), which is traditionally used for the soundboards of violins. The most valuable tonewoods, such as the ripple sycamore (Acer pseudoplatanus), used for the backs of violins, combine acoustic properties with decorative color and grain which enhance the appearance of the finished instrument.
What's the common name for Picea abies?
A: European spruce
Problem: Please answer a question about the following article about Royal Dutch Shell:
On 20 May 2011, Royal Dutch Shell's final investment decision for the world's first floating liquefied natural gas (FLNG) facility was finalized following the discovery of the remote offshore Prelude field—located off Australia's northwestern coast and estimated to contain about 3 trillion cubic feet of natural gas equivalent reserves—in 2007. FLNG technology is based on liquefied natural gas (LNG) developments that were pioneered in the mid-20th century and facilitates the exploitation of untapped natural gas reserves located in remote areas, often too small to extract any other way.
The final investment decision for what was finalized by Royal Dutch Shell in May 2011?
A: the world's first floating liquefied natural gas (FLNG) facility
Problem: Please answer a question about the following article about Red:
Red was the color of the banner of the Byzantine emperors. In Western Europe, Emperor Charlemagne painted his palace red as a very visible symbol of his authority, and wore red shoes at his coronation. Kings, princes and, beginning in 1295, Roman Catholic cardinals began to wear red costumes. When Abbe Suger rebuilt Saint Denis Basilica outside Paris in the early 12th century, he added stained glass windows colored blue cobalt glass and red glass tinted with copper. Together they flooded the basilica with a mystical light. Soon stained glass windows were being added to cathedrals all across France, England and Germany. In Medieval painting red was used to attract attention to the most important figures; both Christ and the Virgin Mary were commonly painted wearing red mantles.
Who rebuilt the basilica of Saint Denis?
A:
Abbe Suger
