Problem: Lighting:

Analysis of lighting quality particularly emphasizes use of natural lighting, but also considers spectral content if artificial light is to be used. Not only will greater reliance on natural light reduce energy consumption, but will favorably impact human health and performance. New studies have shown that the performance of students is influenced by the time and duration of daylight in their regular schedules. Designing school facilities to incorporate the right types of light at the right time of day for the right duration may improve student performance and well-being. Similarly, designing lighting systems that maximize the right amount of light at the appropriate time of day for the elderly may help relieve symptoms of Alzheimer's Disease. The human circadian system is entrained to a 24-hour light-dark pattern that mimics the earth's natural light/dark pattern. When those patterns are disrupted, they disrupt the natural circadian cycle. Circadian disruption may lead to numerous health problems including breast cancer, seasonal affective disorder, delayed sleep phase syndrome, and other ailments.

What happens to the natural carcidan cycle when light-dark patterns are disrupted?
---
A: disrupt the natural circadian cycle

Problem: The two volume biography of Whitehead by Victor Lowe is the most definitive presentation of the life of Whitehead. However, many details of Whitehead's life remain obscure because he left no Nachlass; his family carried out his instructions that all of his papers be destroyed after his death. Additionally, Whitehead was known for his "almost fanatical belief in the right to privacy", and for writing very few personal letters of the kind that would help to gain insight on his life. This led to Lowe himself remarking on the first page of Whitehead's biography, "No professional biographer in his right mind would touch him."
What did the author of Whitehead's biography comment on the first page regarding the ease of obtaining information about Whitehead?

Context and question: Pubs within a chain will usually have items in common, such as fittings, promotions, ambience and range of food and drink on offer. A pub chain will position itself in the marketplace for a target audience. One company may run several pub chains aimed at different segments of the market. Pubs for use in a chain are bought and sold in large units, often from regional breweries which are then closed down. Newly acquired pubs are often renamed by the new owners, and many people resent the loss of traditional names, especially if their favourite regional beer disappears at the same time.
What often happens to regional breweries after they sell their pubs?
Answer: closed down

Question: A uniquely Creole tradition is the touloulous. These women wear decorative gowns, gloves, masks and headdresses that cover them completely, making them unrecognisable, even to the colour of their skin. On Friday and Saturday nights of Carnival, touloulou balls are held in so-called universities; in reality, large dance halls that open only at Carnival time. Touloulous get in free, and are even given condoms in the interest of the sexual health of the community. Men attend the balls, but they pay admittance and are not disguised. The touloulous pick their dance partners, who may not refuse. The setup is designed to make it easy for a woman to create a temporary liaison with a man in total anonymity. Undisguised women are not welcomed. By tradition, if such a woman gets up to dance, the orchestra stops playing. Alcohol is served at bars the disguised women whisper to the men "touloulou thirsty", at which a round of drinks is expected, to be drunk through a straw protect their anonymity.
Is there an answer to this question: Why do the women drink through a straw?

Answer: protect their anonymity

The ReWritable Audio CD is designed to be used in a consumer audio CD recorder, which will not (without modification) accept standard CD-RW discs. These consumer audio CD recorders use the Serial Copy Management System (SCMS), an early form of digital rights management (DRM), to conform to the United States' Audio Home Recording Act (AHRA). The ReWritable Audio CD is typically somewhat more expensive than CD-RW due to (a) lower volume and (b) a 3% AHRA royalty used to compensate the music industry for the making of a copy.
What year was the digital rights management published?
A:
unanswerable
