input question: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume.  San Francisco and Baltimore both have large manufacturing and production industries and both border large oceans. San Francisco has been burning large amounts of fossil fuels recently to fuel their increased manufacturing and production of automobiles. Baltimore, however, has shifted to renewable resources recently, and as a result they have drastically decreased the amount of fossil fuels that are used to produce and manufacture steel.  Which city, San Francisco or Baltimore, releases less carbon dioxide into the atmosphere????
output answer: Baltimore

input question: The Human Immunodeficiency Virus ( HIV ) is the virus that causes Acquired Immunodeficiency Syndrome ( AIDS ). Most researchers believe that the HIV originated in sub-Saharan Africa during the 20th century. HIV is transmitted by sexual contact and by contact with infected bodily fluids, such as blood, semen, breast milk, and vaginal secretions. It is also passed from mother to fetus. HIV is now a pandemic , with an estimated (as of 2008) 38.6 million people now living with the disease worldwide. It is estimated that AIDS has killed more than 25 million people since it was first recognized in 1981. For further information about HIV/AIDS, see the CDC (Centers for Disease Control and Prevention) web site at http://www.cdc.gov/hiv/resources/factsheets/ .  Two neighboring countries had health epidemics. While Ghana had a measles problem, Niger had a very serious HIV problem that seemed to get out of control.  Which country had more people transmitting HIV by contact with infected breast milk????
output answer: Niger

input question: Beginning in the late 1970’s, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels.  Factories around the world produce lots of CFCs which deplete the ozone layer. One year a large number of these factories decided they would implement efforts to reduce the amount of CFCs they release into the atmosphere. As a result the depletion of the ozone layer greatly decreased. However, the companies realized that this was hurting profits too much and reverted their decision. As a result the ozone layer began to rapidly deplete again.  Will the ozone layer deplete faster or slower if more companies that emit CFCs are built????
output answer: more

input question: Artworks are sold at affordable prices [6] ranging from £5 to £1500. For many of the works, the price goes up as the edition sells out. The edition runs range from 30 to 10,000 editions. Each work comes with a digital certificate that is “signed, numbered and authenticated by the artist” [7][8] Once an edition is sold out, collectors can resell their works in the online marketplace.  The prices of John's paintings started to rise immediately after the edition sold out. they used to cost $10 but now they sell for at least $200. john had 45 paintings in this edition. The prices of Mike's paintings are at $8 a piece, because his edition hasn't sold out yet. Mike's edition run was 250 editions.  Which edition consisted of fewer paintings????
output answer:
John's
