Problem: Please answer a question about the following article about Pope Paul VI:
Paul VI was concerned but not surprised by the negative reaction in Western Europe and the United States. He fully anticipated this reaction to be a temporary one: "Don't be afraid", he reportedly told Edouard Gagnon on the eve of the encyclical, "in twenty years time they'll call me a prophet." His biography on the Vatican's website notes of his reaffirmations of priestly celibacy and the traditional teaching on contraception that "[t]he controversies over these two pronouncements tended to overshadow the last years of his pontificate". Pope John Paul II later reaffirmed and expanded upon Humanae vitae with the encyclical Evangelium vitae.
To what did Western Europe and the United States demonstrate a negative response?

Problem: Please answer a question about the following article about Roman Republic:
Many aspects of Roman culture were borrowed from the Greeks. In architecture and sculpture, the difference between Greek models and Roman paintings are apparent. The chief Roman contributions to architecture were the arch and the dome. Rome has also had a tremendous impact on European cultures following it. Its significance is perhaps best reflected in its endurance and influence, as is seen in the longevity and lasting importance of works of Virgil and Ovid. Latin, the Republic's primary language, remains used for liturgical purposes by the Roman Catholic Church, and up to the 19th century was used extensively in scholarly writings in, for example, science and mathematics. Roman law laid the foundations for the laws of many European countries and their colonies.[citation needed]
What was considered to be the dominant language in the Roman Republic?
A:
Latin
