Problem: Please answer a question about the following article about Mosaic:
Mosaic art also flourished in Christian Petra where three Byzantine churches were discovered. The most important one was uncovered in 1990. It is known that the walls were also covered with golden glass mosaics but only the floor panels survived as usual. The mosaic of the seasons in the southern aisle is from this first building period from the middle of the 5th century. In the first half of the 6th century the mosaics of the northern aisle and the eastern end of the southern aisle were installed. They depict native as well as exotic or mythological animals, and personifications of the Seasons, Ocean, Earth and Wisdom.
When was the most important Byzantine church re-discovered?

Problem: Please answer a question about the following article about Insect:
Insects have segmented bodies supported by exoskeletons, the hard outer covering made mostly of chitin. The segments of the body are organized into three distinctive but interconnected units, or tagmata: a head, a thorax and an abdomen. The head supports a pair of sensory antennae, a pair of compound eyes, and, if present, one to three simple eyes (or ocelli) and three sets of variously modified appendages that form the mouthparts. The thorax has six segmented legsone pair each for the prothorax, mesothorax and the metathorax segments making up the thoraxand, none, two or four wings. The abdomen consists of eleven segments, though in a few species of insects, these segments may be fused together or reduced in size. The abdomen also contains most of the digestive, respiratory, excretory and reproductive internal structures.:2248 Considerable variation and many adaptations in the body parts of insects occur, especially wings, legs, antenna and mouthparts.
Chitin is what kind of outer covering on an insect?
A: hard

Problem: Please answer a question about the following article about Napoleon:
There have been modern studies that have supported the original autopsy finding. In a 2008 study, researchers analysed samples of Napoleon's hair from throughout his life, as well as samples from his family and other contemporaries. All samples had high levels of arsenic, approximately 100 times higher than the current average. According to these researchers, Napoleon's body was already heavily contaminated with arsenic as a boy, and the high arsenic concentration in his hair was not caused by intentional poisoning; people were constantly exposed to arsenic from glues and dyes throughout their lives.[note 7] Studies published in 2007 and 2008 dismissed evidence of arsenic poisoning, and confirmed evidence of peptic ulcer and gastric cancer as the cause of death.
Studies published in 2007 and 2008 support what possible causes of Napoleon's death?
A:
peptic ulcer and gastric cancer
