Input: Read this: While worship in the Temple in Jerusalem included musical instruments (2 Chronicles 29:2527), traditional Jewish religious services in the Synagogue, both before and after the last destruction of the Temple, did not include musical instruments given the practice of scriptural cantillation. The use of musical instruments is traditionally forbidden on the Sabbath out of concern that players would be tempted to repair (or tune) their instruments, which is forbidden on those days. (This prohibition has been relaxed in many Reform and some Conservative congregations.) Similarly, when Jewish families and larger groups sing traditional Sabbath songs known as zemirot outside the context of formal religious services, they usually do so a cappella, and Bar and Bat Mitzvah celebrations on the Sabbath sometimes feature entertainment by a cappella ensembles. During the Three Weeks musical instruments are prohibited. Many Jews consider a portion of the 49-day period of the counting of the omer between Passover and Shavuot to be a time of semi-mourning and instrumental music is not allowed during that time. This has led to a tradition of a cappella singing sometimes known as sefirah music.
Question: What was included in tradition Jewish services in synagogues?

QUES: Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. In the Eocene epoch, about 40 Ma Australia-New Guinea separated from Antarctica, so that latitudinal currents could isolate Antarctica from Australia, and the first ice began to appear. During the EoceneOligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm and had been decreasing from earlier levels in the thousands of ppm.

What currents began isolating Australia in 66 Ma

QUES: Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry dozens of aircraft, including fighter jets and helicopters. As of 3 March 2016, there are thirty-seven active aircraft carriers in the world within twelve navies. The United States Navy has 10 large nuclear-powered carriers (known as supercarriers, carrying up to 90 aircraft each), the largest carriers in the world; the total deckspace is over twice that of all other nations' combined. As well as the supercarrier fleet, the US Navy has nine amphibious assault ships used primarily for helicopters (sometimes called helicopter carriers); these can also carry up to 25 fighter jets, and in some cases, are as large as some other nations' fixed-wing carriers.
Who owns the smallest carriers in the world?

The bank is based in Frankfurt, the largest financial centre in the Eurozone. Its location in the city is fixed by the Amsterdam Treaty. The bank moved to new purpose-built headquarters in 2014 which were designed a Vienna-based architectural office named Coop Himmelbau. The building is approximately 180 metres (591 ft) tall and will be accompanied with other secondary buildings on a landscaped site on the site of the former wholesale market in the eastern part of Frankfurt am Main. The main construction began in October 2008, and it was expected that the building will become an architectural symbol for Europe. While it was designed to accommodate double the number of staff who operate in the former Eurotower, that building has been retained since the ECB took responsibility for banking supervision and more space was hence required.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where is the European Central bank unknown?
Ah, so.. unanswerable

Question: Reaction to the novel varied widely upon publication. Literary analysis of it is sparse, considering the number of copies sold and its widespread use in education. Author Mary McDonough Murphy, who collected individual impressions of To Kill a Mockingbird by several authors and public figures, calls the book, "an astonishing phenomenon". In 2006, British librarians ranked the book ahead of the Bible as one "every adult should read before they die". It was adapted into an Oscar-winning film in 1962 by director Robert Mulligan, with a screenplay by Horton Foote. Since 1990, a play based on the novel has been performed annually in Harper Lee's hometown of Monroeville, Alabama.
Try to answer this question if possible: British librarians in 2006 ranked the book ahead of what famous volume?
Answer: Bible

Problem: The FBI is near-impenetrable, with applicants intensely scrutinized and assessed over an extended period. To apply to become an FBI agent, one must be between the ages of 23 and 37. Due to the decision in Robert P. Isabella v. Department of State and Office of Personnel Management, 2008 M.S.P.B. 146, preference-eligible veterans may apply after age 37. In 2009, the Office of Personnel Management issued implementation guidance on the Isabella decision. The applicant must also hold American citizenship, be of high moral character, have a clean record, and hold at least a four-year bachelor's degree. At least three years of professional work experience prior to application is also required. All FBI employees require a Top Secret (TS) security clearance, and in many instances, employees need a TS/SCI (Top Secret/Sensitive Compartmented Information) clearance. To obtain a security clearance, all potential FBI personnel must pass a series of Single Scope Background Investigations (SSBI), which are conducted by the Office of Personnel Management. Special Agents candidates also have to pass a Physical Fitness Test (PFT), which includes a 300-meter run, one-minute sit-ups, maximum push-ups, and a 1.5-mile (2.4 km) run. Personnel must pass a polygraph test with questions including possible drug use. Applicants who fail polygraphs may not gain employment with the FBI.
