Problem: Please answer a question about the following article about Age of Enlightenment:
Science came to play a leading role in Enlightenment discourse and thought. Many Enlightenment writers and thinkers had backgrounds in the sciences and associated scientific advancement with the overthrow of religion and traditional authority in favour of the development of free speech and thought. Scientific progress during the Enlightenment included the discovery of carbon dioxide (fixed air) by the chemist Joseph Black, the argument for deep time by the geologist James Hutton, and the invention of the steam engine by James Watt. The experiments of Lavoisier were used to create the first modern chemical plants in Paris, and the experiments of the Montgolfier Brothers enabled them to launch the first manned flight in a hot-air balloon on 21 November 1783, from the Chateau de la Muette, near the Bois de Boulogne.
Who launched the first manned flight in a hot-air balloon in November 1783?
A: the Montgolfier Brothers

What is the estimated number of slaves that were transported each year?
A: 6,000 to 7,000 slaves
Problem: Please answer a question about the following article about Asphalt:
People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 5 mg/m3 over a 15-minute period. Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that effect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 C (390 F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement.
What feature in the treatment of asphalt in the workplace causes the most potential danger?
A: temperature
Problem: Please answer a question about the following article about San Diego:
San Diego County has one of the highest counts of animal and plant species that appear on the endangered species list among counties in the United States. Because of its diversity of habitat and its position on the Pacific Flyway, San Diego County has recorded the presence of 492 bird species, more than any other region in the country. San Diego always scores very high in the number of bird species observed in the annual Christmas Bird Count, sponsored by the Audubon Society, and it is known as one of the "birdiest" areas in the United States.
What birding event does the Audubon Society host every year?
A:
Christmas Bird Count
