Here is a question about this article: The committee considered an eight-bit code, since eight bits (octets) would allow two four-bit patterns to efficiently encode two digits with binary-coded decimal. However, it would require all data transmission to send eight bits when seven could suffice. The committee voted to use a seven-bit code to minimize costs associated with data transmission. Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.:217, 236 § 5 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.
What is the answer to this question: What allowed for a parity bit for error chicking if needed?

So... perforated tape at the time could record eight bits in one position


Here is a question about this article: In the classical case, the invariance, or symmetry, group and the covariance group coincide, but, interestingly enough, they part ways in relativistic physics. The symmetry group of the general theory of relativity includes all differentiable transformations, i.e., all properties of an object are dynamical, in other words there are no absolute objects. The formulations of the general theory of relativity, unlike those of classical mechanics, do not share a standard, i.e., there is no single formulation paired with transformations. As such the covariance group of the general theory of relativity is just the covariance group of every theory.
What is the answer to this question:  The covariance group of the general theory of relativity is the covariance group of how many theories?

So... every


Here is a question about this article: Better acquaintance with Greek and Roman technical writings also influenced the development of European science (see the history of science in the Renaissance). This was despite what A. C. Crombie (viewing the Renaissance in the 19th-century manner as a chapter in the heroic March of Progress) calls "a backwards-looking admiration for antiquity", in which Platonism stood in opposition to the Aristotelian concentration on the observable properties of the physical world. But Renaissance humanists, who considered themselves as restoring the glory and nobility of antiquity, had no interest in scientific innovation. However, by the mid-to-late 16th century, even the universities, though still dominated by Scholasticism, began to demand that Aristotle be read in accurate texts edited according to the principles of Renaissance philology, thus setting the stage for Galileo's quarrels with the outmoded habits of Scholasticism.
What is the answer to this question: What group was neutral about this issue as they felt the subject unimportant?

So...
Renaissance humanists
