Problem: Spanish language in the United States:

For decades, the U.S. federal government strenuously tried to force Puerto Ricans to adopt English, to the extent of making them use English as the primary language of instruction in their high schools. It was completely unsuccessful, and retreated from that policy in 1948. Puerto Rico was able to maintain its Spanish language, culture, and identity because the relatively small, densely populated island was already home to nearly a million people at the time of the U.S. takeover, all of those spoke Spanish, and the territory was never hit with a massive influx of millions of English speakers like the vast territory acquired from Mexico 50 years earlier.

How did Mexico try to make Puerto Rico's language English?

Problem: The company aims to reduce its external environmental impact through energy-efficient evolution of products, and also reduce its direct operational impact through energy-efficiency programs. Internal energy-efficiency programs reportedly save the company more than $3 million annually in energy-cost savings. The largest component of the company's internal energy-efficiency savings comes through PC power management: the company expects to save $1.8 million in energy costs through using specialized energy-management software on a network of 50,000 PCs.
How many PCs does Dell employ energy management hardware on?

Context and question: A Vestal's dress represented her status outside the usual categories that defined Roman women, with elements of both virgin bride and daughter, and Roman matron and wife. Unlike male priests, Vestals were freed of the traditional obligations of marrying and producing children, and were required to take a vow of chastity that was strictly enforced: a Vestal polluted by the loss of her chastity while in office was buried alive. Thus the exceptional honor accorded a Vestal was religious rather than personal or social; her privileges required her to be fully devoted to the performance of her duties, which were considered essential to the security of Rome.
What vow was required of Vestals?
Answer: chastity

Question: The monastic communities of the Judean Desert also decorated their monasteries with mosaic floors. The Monastery of Martyrius was founded in the end of the 5th century and it was re-discovered in 198285. The most important work of art here is the intact geometric mosaic floor of the refectory although the severely damaged church floor was similarly rich. The mosaics in the church of the nearby Monastery of Euthymius are of later date (discovered in 1930). They were laid down in the Umayyad era, after a devastating earthquake in 659. Two six pointed stars and a red chalice are the most important surviving features.
Is there an answer to this question: When was the Monastery of Martyrius created?

Answer: the end of the 5th century

Problem: Ashkenazi Jews:

Religious Jews have Minhagim, customs, in addition to Halakha, or religious law, and different interpretations of law. Different groups of religious Jews in different geographic areas historically adopted different customs and interpretations. On certain issues, Orthodox Jews are required to follow the customs of their ancestors, and do not believe they have the option of picking and choosing. For this reason, observant Jews at times find it important for religious reasons to ascertain who their household's religious ancestors are in order to know what customs their household should follow. These times include, for example, when two Jews of different ethnic background marry, when a non-Jew converts to Judaism and determines what customs to follow for the first time, or when a lapsed or less observant Jew returns to traditional Judaism and must determine what was done in his or her family's past. In this sense, "Ashkenazic" refers both to a family ancestry and to a body of customs binding on Jews of that ancestry. Reform Judaism, which does not necessarily follow those minhagim, did nonetheless originate among Ashkenazi Jews.

For religious Jews, what does Halakha mean?

A:
religious law
