Problem: University of Notre Dame:

Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend "Venite Ad Me Omnes". Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.

What is the Grotto at Notre Dame?

A: a Marian place of prayer and reflection


Problem: After the Communist Party of China took power in 1949, the flag of China became a red flag with a large star symbolizing the Communist Party, and smaller stars symbolizing workers, peasants, the urban middle class and rural middle class. The flag of the Communist Party of China became a red banner with a hammer and sickle, similar to that on the Soviet flag. In the 1950s and 1960s, other Communist regimes such as Vietnam and Laos also adopted red flags. Some Communist countries, such as Cuba, chose to keep their old flags; and other countries used red flags which had nothing to do with Communism or socialism; the red flag of Nepal, for instance, represents the national flower.

Question: The main representatives of the new style, often referred to as ars nova as opposed to the ars antiqua, were the composers Philippe de Vitry and Guillaume de Machaut. In Italy, where the Provençal troubadours had also found refuge, the corresponding period goes under the name of trecento, and the leading composers were Giovanni da Cascia, Jacopo da Bologna and Francesco Landini. Prominent reformer of Orthodox Church music from the first half of 14th century was John Kukuzelis; he also introduced a system of notation widely used in the Balkans in the following centuries.

Unlike other Germanic languages, Dutch doesn't have phonological aspiration of consonants. Like English, Dutch did not participate in the second consonant shift. Like most Germanic languages, the Dutch consonant system did not undergo the High German consonant shift and has a syllable structure that allows fairly complex consonant clusters. Dutch also retains full use of the velar fricatives that were present in Proto-Germanic, but lost or modified in many other Germanic languages. Dutch has final-obstruent devoicing: at the end of a word, voicing distinction is neutralised and all obstruents are pronounced voiceless. For example, goede ("good") is /ˈɣudə/ but the related form goed is /ɣut/. Dutch shares with German Final-obstruent devoicing (Du brood [broːt] and German Brot vs Eng bread).
Along with English, what pronunciation shift did Dutch not undergo?
A:
the second consonant shift
