Problem: A cappella:

The popularization of the Jewish chant may be found in the writings of the Jewish philosopher Philo, born 20 BCE. Weaving together Jewish and Greek thought, Philo promoted praise without instruments, and taught that "silent singing" (without even vocal chords) was better still. This view parted with the Jewish scriptures, where Israel offered praise with instruments by God's own command (2 Chronicles 29:25). The shofar is the only temple instrument still being used today in the synagogue, and it is only used from Rosh Chodesh Elul through the end of Yom Kippur. The shofar is used by itself, without any vocal accompaniment, and is limited to a very strictly defined set of sounds and specific places in the synagogue service.

Who commanded Christians to offer praise with instruments?

A: unanswerable

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Due to the tree structure of the filter bank, pre-echo problems are made worse, as the combined impulse response of the two filter banks does not, and cannot, provide an optimum solution in time/frequency resolution. Additionally, the combining of the two filter banks' outputs creates aliasing problems that must be handled partially by the "aliasing compensation" stage; however, that creates excess energy to be coded in the frequency domain, thereby decreasing coding efficiency.[citation needed]
The need to code excess energy in the frequency domain decreases what kind of efficiency?
A: coding

Question: The foundation trust invests undistributed assets, with the exclusive goal of maximizing the return on investment. As a result, its investments include companies that have been criticized for worsening poverty in the same developing countries where the foundation is attempting to relieve poverty. These include companies that pollute heavily and pharmaceutical companies that do not sell into the developing world. In response to press criticism, the foundation announced in 2007 a review of its investments to assess social responsibility. It subsequently cancelled the review and stood by its policy of investing for maximum return, while using voting rights to influence company practices.
Is there an answer to this question: When did the company decide to review its lack of sales in the developing world?

Answer: unanswerable


In 1966 an agreement with the Vatican, fostered in part by the death in 1960 of anti-communist archbishop of Zagreb Aloysius Stepinac and shifts in the church's approach to resisting communism originating in the Second Vatican Council, accorded new freedom to the Yugoslav Roman Catholic Church, particularly to catechize and open seminaries. The agreement also eased tensions, which had prevented the naming of new bishops in Yugoslavia since 1945. Tito's new socialism met opposition from traditional communists culminating in conspiracy headed by Aleksandar Ranković. In the same year Tito declared that Communists must henceforth chart Yugoslavia's course by the force of their arguments (implying an abandonment of Leninist orthodoxy and development of liberal Communism). The State Security Administration (UDBA) saw its power scaled back and its staff reduced to 5000.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What acronym describes the State Security Administration?
Ah, so..
UDBA
