Input: Article: Because of their ability to quickly grow and the relative ease with which they can be manipulated, bacteria are the workhorses for the fields of molecular biology, genetics and biochemistry. By making mutations in bacterial DNA and examining the resulting phenotypes, scientists can determine the function of genes, enzymes and metabolic pathways in bacteria, then apply this knowledge to more complex organisms. This aim of understanding the biochemistry of a cell reaches its most complex expression in the synthesis of huge amounts of enzyme kinetic and gene expression data into mathematical models of entire organisms. This is achievable in some well-studied bacteria, with models of Escherichia coli metabolism now being produced and tested. This understanding of bacterial metabolism and genetics allows the use of biotechnology to bioengineer bacteria for the production of therapeutic proteins, such as insulin, growth factors, or antibodies.

Now answer this question: What sciences use bacteria?

Output: molecular biology, genetics and biochemistry

Input: Article: In 1972, in a mosque in the city of Sana'a, Yemen, manuscripts were discovered that were later proved to be the most ancient Quranic text known to exist at the time. The Sana'a manuscripts contain palimpsests, a manuscript page from which the text has been washed off to make the parchment reusable againa practice which was common in ancient times due to scarcity of writing material. However, the faint washed-off underlying text (scriptio inferior) is still barely visible and believed to be "pre-Uthmanic" Quranic content, while the text written on top (scriptio superior) is believed to belong to Uthmanic time. Studies using radiocarbon dating indicate that the parchments are dated to the period before 671 AD with a 99 percent probability.

Now answer this question: Before which year were the Sana'a manuscripts produced?

Output: 671 AD

Input: Article: Bermuda watercolours painted by local artists are sold at various galleries. Hand-carved cedar sculptures are another speciality. One such 7 ft (2.1 m) sculpture, created by Bermudian sculptor Chesley Trott, is installed at the airport's baggage claim area. In 2010, his sculpture The Arrival was unveiled near the bay to commemorate the freeing of slaves from the American brig Enterprise in 1835. Local artwork may also be viewed at several galleries around the island. Alfred Birdsey was one of the more famous and talented watercolourists; his impressionistic landscapes of Hamilton, St George's and the surrounding sailboats, homes, and bays of Bermuda are world-renowned.

Now answer this question: What type of art work does Chesley Trott produce?

Output:
Hand-carved cedar sculptures
