Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the next century which is the beginning of the Classical period, it was considered that beauty in visible things as in everything else, consisted of symmetry and proportions. The artists tried also to represent motion in a specific moment (Myron), which may be considered as the reappearance of the dormant Minoan element. Anatomy and geometry are fused in one, and each does something to the other. The Greek sculptors tried to clarify it by looking for mathematical proportions, just as they sought some reality behind appearances. Polykleitos in his Canon wrote that beauty consists in the proportion not of the elements (materials), but of the parts, that is the interrelation of parts with one another and with the whole. It seems that he was influenced by the theories of Pythagoras. The famous Apollo of Mantua and its variants are early forms of the Apollo Citharoedus statue type, in which the god holds the cithara in his left arm. The type is represented by neo-Attic Imperial Roman copies of the late 1st or early 2nd century, modelled upon a supposed Greek bronze original made in the second quarter of the 5th century BCE, in a style similar to works of Polykleitos but more archaic. The Apollo held the cythara against his extended left arm, of which in the Louvre example, a fragment of one twisting scrolling horn upright remains against his biceps.
What type of art is modeled after a supposed Greek bronze original made in the second quarter of the 5th Century BCE.
A: neo-Attic Imperial Roman copies of the late 1st or early 2nd century


Context and question: Many people gain a sense of positive self-esteem from their identity groups, which furthers a sense of community and belonging. Another issue that researchers have attempted to address is the question of why people engage in discrimination, i.e., why they tend to favor those they consider a part of their "in-group" over those considered to be outsiders. Both questions have been given extensive attention by researchers working in the social identity tradition. For example, in work relating to social identity theory it has been shown that merely crafting cognitive distinction between in- and out-groups can lead to subtle effects on people's evaluations of others (Cote & Levine 2002).
Cognitive distinctions between out groups can lead to what?
Answer: unanswerable


Question: 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.
Is there an answer to this question: How is silent singing used when practiced in a synagogue service?

Answer: unanswerable
