The papal bull defining the dogma, Ineffabilis Deus, mentioned in particular the patrististic interpretation of Genesis 3:15 as referring to a woman, Mary, who would be eternally at enmity with the evil serpent and completely triumphing over him. It said the Fathers saw foreshadowings of Mary's "wondrous abundance of divine gifts and original innocence" "in that ark of Noah, which was built by divine command and escaped entirely safe and sound from the common shipwreck of the whole world; in the ladder which Jacob saw reaching from the earth to heaven, by whose rungs the angels of God ascended and descended, and on whose top the Lord himself leaned; in that bush which Moses saw in the holy place burning on all sides, which was not consumed or injured in any way but grew green and blossomed beautifully; in that impregnable tower before the enemy, from which hung a thousand bucklers and all the armor of the strong; in that garden enclosed on all sides, which cannot be violated or corrupted by any deceitful plots; in that resplendent city of God, which has its foundations on the holy mountains; in that most august temple of God, which, radiant with divine splendours, is full of the glory of God; and in very many other biblical types of this kind."

Problem: Please answer a question about the following article about Pope Paul VI:
His organisational skills led him to a career in the Roman Curia, the papal civil service. In 1931, Pacelli appointed him to teach history at the Papal Academy for Diplomats In 1937, after his mentor Giuseppe Pizzardo was named a cardinal and was succeeded by Domenico Tardini, Montini was named Substitute for Ordinary Affairs under Cardinal Pacelli, the Secretary of State under Pope Pius XI. From Pius XI, whom he viewed with awe, he adopted the view, that learning is a life long process, and that history was the magister vitae teacher of life His immediate supervisor in the Vatican was Domenico Tardini, with whom he got along well. The election of Pacelli to the papacy in 1939, anticipated by everybody and openly promoted by Pope Pius XI in his last years, was a good omen for Montini, whose position was confirmed in the position under the new Cardinal Secretary of State Luigi Maglione. He met the pope every morning until 1954 and thus developed a rather close relationship:
Where did Montini teach history?
A: Papal Academy for Diplomats
Problem: Please answer a question about the following article about Geological history of Earth:
The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.
How many years is the Hirnantian faunal stage believed to have lasted?
A:
0.5 to 1.5 million years
