Question: A strong and prominent a cappella tradition was begun in the midwest part of the United States in 1911 by F. Melius Christiansen, a music faculty member at St. Olaf College in Northfield, Minnesota. The St. Olaf College Choir was established as an outgrowth of the local St. John's Lutheran Church, where Christiansen was organist and the choir was composed, at least partially, of students from the nearby St. Olaf campus. The success of the ensemble was emulated by other regional conductors, and a rich tradition of a cappella choral music was born in the region at colleges like Concordia College (Moorhead, Minnesota), Augustana College (Rock Island, Illinois), Wartburg College (Waverly, Iowa), Luther College (Decorah, Iowa), Gustavus Adolphus College (St. Peter, Minnesota), Augustana College (Sioux Falls, South Dakota), and Augsburg College (Minneapolis, Minnesota). The choirs typically range from 40 to 80 singers and are recognized for their efforts to perfect blend, intonation, phrasing and pitch in a large choral setting.
Is there an answer to this question: When did a cappella begin to take hold in the United States?

Answer: 1911


Question: The Gaza Strip was occupied by Egypt from 1948 to 1967 and then by Israel after 1967. In 2005, as part of Israel's unilateral disengagement plan, Israel removed all of its settlers and forces from the territory. Israel does not consider the Gaza Strip to be occupied territory and declared it a "foreign territory". That view has been disputed by numerous international humanitarian organizations and various bodies of the United Nations. Following June 2007, when Hamas assumed power in the Gaza Strip, Israel tightened its control of the Gaza crossings along its border, as well as by sea and air, and prevented persons from entering and exiting the area except for isolated cases it deemed humanitarian. Gaza has a border with Egypt and an agreement between Israel, the European Union and the PA governed how border crossing would take place (it was monitored by European observers). Egypt adhered to this agreement under Mubarak and prevented access to Gaza until April 2011 when it announced it was opening its border with Gaza.

Answer: June 2007


Question: Details of the overall United States intelligence budget are classified. Under the Central Intelligence Agency Act of 1949, the Director of Central Intelligence is the only federal government employee who can spend "un-vouchered" government money. The government has disclosed a total figure for all non-military intelligence spending since 2007; the fiscal 2013 figure is $52.6 billion. According to the 2013 mass surveillance disclosures, the CIA's fiscal 2013 budget is $14.7 billion, 28% of the total and almost 50% more than the budget of the National Security Agency. CIA's HUMINT budget is $2.3 billion, the SIGINT budget is $1.7 billion, and spending for security and logistics of CIA missions is $2.5 billion. "Covert action programs", including a variety of activities such as the CIA's drone fleet and anti-Iranian nuclear program activities, accounts for $2.6 billion.
Is there an answer to this question: What year was the Central Intelligence Agency Act created?

Answer: 1949


Question: Adaptation of the endosymbiont to the host's lifestyle leads to many changes in the endosymbiont–the foremost being drastic reduction in its genome size. This is due to many genes being lost during the process of metabolism, and DNA repair and recombination. While important genes participating in the DNA to RNA transcription, protein translation and DNA/RNA replication are retained. That is, a decrease in genome size is due to loss of protein coding genes and not due to lessening of inter-genic regions or open reading frame (ORF) size. Thus, species that are naturally evolving and contain reduced sizes of genes can be accounted for an increased number of noticeable differences between them, thereby leading to changes in their evolutionary rates. As the endosymbiotic bacteria related with these insects are passed on to the offspring strictly via vertical genetic transmission, intracellular bacteria goes through many hurdles during the process, resulting in the decrease in effective population sizes when compared to the free living bacteria. This incapability of the endosymbiotic bacteria to reinstate its wild type phenotype via a recombination process is called as Muller's ratchet phenomenon. Muller's ratchet phenomenon together with less effective population sizes has led to an accretion of deleterious mutations in the non-essential genes of the intracellular bacteria. This could have been due to lack of selection mechanisms prevailing in the rich environment of the host.
Is there an answer to this question: What happens when there is an increase in the effective population sizes for free living bacteria?
