The problem: Answer a question about this article:
In some species, both parents care for nestlings and fledglings; in others, such care is the responsibility of only one sex. In some species, other members of the same speciesusually close relatives of the breeding pair, such as offspring from previous broodswill help with the raising of the young. Such alloparenting is particularly common among the Corvida, which includes such birds as the true crows, Australian magpie and fairy-wrens, but has been observed in species as different as the rifleman and red kite. Among most groups of animals, male parental care is rare. In birds, however, it is quite commonmore so than in any other vertebrate class. Though territory and nest site defence, incubation, and chick feeding are often shared tasks, there is sometimes a division of labour in which one mate undertakes all or most of a particular duty.
What is more common in birds than any other vertebrate class?
****
The answer: male parental care

Problem: Please answer a question about the following article about Punjab, Pakistan:
The major and native language spoken in the Punjab is Punjabi (which is written in a Shahmukhi script in Pakistan) and Punjabis comprise the largest ethnic group in country. Punjabi is the provincial language of Punjab. There is not a single district in the province where Punjabi language is mother-tongue of less than 89% of population. The language is not given any official recognition in the Constitution of Pakistan at the national level. Punjabis themselves are a heterogeneous group comprising different tribes, clans (Urdu: ) and communities. In Pakistani Punjab these tribes have more to do with traditional occupations such as blacksmiths or artisans as opposed to rigid social stratifications. Punjabi dialects spoken in the province include Majhi (Standard), Saraiki and Hindko. Saraiki is mostly spoken in south Punjab, and Pashto, spoken in some parts of north west Punjab, especially in Attock District and Mianwali District.
What is the largest ethnic group in Pakistan?

Prior Diego saw immediately one of the paramount reasons for the spread of the unorthodox movement: the representatives of the Holy Church acted and moved with an offensive amount of pomp and ceremony. On the other hand, the Cathars lived in a state of self-sacrifice that was widely appealing. For these reasons, Prior Diego suggested that the papal legates begin to live a reformed apostolic life. The legates agreed to change if they could find a strong leader. The prior took up the challenge, and he and Dominic dedicated themselves to the conversion of the Albigensians. Despite this particular mission, in winning the Albigensians over by persuasion Dominic met limited success, "for though in his ten years of preaching a large number of converts were made, it has to be said that the results were not such as had been hoped for."

How did Prior Diego think the members of the Holy Church acted?
Answer: with an offensive amount of pomp and ceremony

Problem: The Treaty of Paris stood until 1871, when France was defeated by Prussia in the Franco-Prussian War of 18701871. While Prussia and several other German states united to form a powerful German Empire, the Emperor of the French, Napoleon III, was deposed to permit the formation of a Third French Republic. During his reign, Napoleon III, eager for the support of the United Kingdom, had opposed Russia over the Eastern Question. Russian interference in the Ottoman Empire, however, did not in any significant manner threaten the interests of France. Thus, France abandoned its opposition to Russia after the establishment of a republic. Encouraged by the decision of the French, and supported by the German minister Otto von Bismarck, Russia renounced the Black Sea clauses of the treaty agreed to in 1856. As the United Kingdom alone could not enforce the clauses, Russia once again established a fleet in the Black Sea.
In what war was France defeated by Prussia?
The answer is the following: Franco-Prussian War

At age eight, Beyonce and childhood friend Kelly Rowland met LaTavia Roberson while in an audition for an all-girl entertainment group. They were placed into a group with three other girls as Girl's Tyme, and rapped and danced on the talent show circuit in Houston. After seeing the group, R&B producer Arne Frager brought them to his Northern California studio and placed them in Star Search, the largest talent show on national TV at the time. Girl's Tyme failed to win, and Beyonce later said the song they performed was not good. In 1995 Beyonce's father resigned from his job to manage the group. The move reduced Beyonce's family's income by half, and her parents were forced to move into separated apartments. Mathew cut the original line-up to four and the group continued performing as an opening act for other established R&B girl groups. The girls auditioned before record labels and were finally signed to Elektra Records, moving to Atlanta Records briefly to work on their first recording, only to be cut by the company. This put further strain on the family, and Beyonce's parents separated. On October 5, 1995, Dwayne Wiggins's Grass Roots Entertainment signed the group. In 1996, the girls began recording their debut album under an agreement with Sony Music, the Knowles family reunited, and shortly after, the group got a contract with Columbia Records.
Who signed the girl group on October 5, 1995?
Dwayne Wiggins's Grass Roots Entertainment

Here is a question about this article: Changing clocks and DST rules has a direct economic cost, entailing extra work to support remote meetings, computer applications and the like. For example, a 2007 North American rule change cost an estimated $500 million to $1 billion, and Utah State University economist William F. Shughart II has estimated the lost opportunity cost at around $1.7 billion USD. Although it has been argued that clock shifts correlate with decreased economic efficiency, and that in 2000 the daylight-saving effect implied an estimated one-day loss of $31 billion on US stock exchanges, the estimated numbers depend on the methodology. The results have been disputed, and the original authors have refuted the points raised by disputers.
What is the answer to this question: What do some call the effect that they say caused a one-day loss for stock exchanges of approximately $31 billion in the year 2000?
****
So...
the daylight-saving effect
