Article: The climate of the Cretaceous is less certain and more widely disputed. Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet. Average temperatures were also higher than today by about 10°C. In fact, by the middle Cretaceous, equatorial ocean waters (perhaps as warm as 20 °C in the deep ocean) may have been too warm for sea life,[dubious – discuss][citation needed] and land areas near the equator may have been deserts despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted.[dubious – discuss] For this reason, large volumes of organic matter that was unable to decompose accumulated, eventually being deposited as "black shale".

Question: What atmospheric gas caused temperatures levels to be 10 degrees higher than today?
Ans: carbon dioxide

Article: In April 2014, it was announced that GE was in talks to acquire the global power division of French engineering group Alstom for a figure of around $13 billion. A rival joint bid was submitted in June 2014 by Siemens and Mitsubishi Heavy Industries (MHI) with Siemens seeking to acquire Alstom's gas turbine business for €3.9 billion, and MHI proposing a joint venture in steam turbines, plus a €3.1 billion cash investment. In June 2014 a formal offer From GE worth $17 billion was agreed by the Alstom board. Part of the transaction involved the French government taking a 20% stake in Alstom to help secure France's energy and transport interests, and French jobs. A rival offer from Siemens-Mitsubishi Heavy Industries was rejected. The acquisition was expected to be completed in 2015.

Question: From which company did the Alstom board reject a rival acquisition proposal?
Ans: Siemens-Mitsubishi Heavy Industries


Article: Mary had been venerated since Early Christianity, and is considered by millions to be the most meritorious saint of the religion. The Eastern and Oriental Orthodox, Roman Catholic, Anglican, and Lutheran Churches believe that Mary, as Mother of Jesus, is the Mother of God and the Theotokos, literally "Giver of birth to God". There is significant diversity in the Marian beliefs and devotional practices of major Christian traditions. The Roman Catholic Church holds distinctive Marian dogmas; namely her status as the mother of God; her Immaculate Conception; her perpetual virginity; and her Assumption into heaven. Many Protestants minimize Mary's role within Christianity, based on the argued brevity of biblical references. Mary (Maryam) also has a revered position in Islam, where a whole chapter of the Qur'an is devoted to her, also describing the birth of Jesus.

Question: What is the basis for Mary's diminished role in Protestantism?
Ans:
brevity of biblical references
