Question: Passage: Roman Catholics believe in the Immaculate Conception of Mary, as proclaimed Ex Cathedra by Pope Pius IX in 1854, namely that she was filled with grace from the very moment of her conception in her mother's womb and preserved from the stain of original sin. The Latin Rite of the Roman Catholic Church has a liturgical feast by that name, kept on December 8. Orthodox Christians reject the Immaculate Conception dogma principally because their understanding of ancestral sin (the Greek term corresponding to the Latin "original sin") differs from the Augustinian interpretation and that of the Roman Catholic Church.

Answer: On what day did Mary attend The Latin Rite of the Roman Catholic Church liturgical feast?

Question: Passage: Longstanding political tensions from the 27 year rule of William Tubman resulted in a military coup in 1980 that overthrew the leadership soon after his death, marking the beginning of political instability. Five years of military rule by the People's Redemption Council and five years of civilian rule by the National Democratic Party of Liberia were followed by the First and Second Liberian Civil Wars.

Recovery proceeds but about 85% of the population live below the international poverty line.

Answer:
How old did William Tubman live to be?
