Extract the answer to the question from the following context. Question: The effective resistance of an electrical circuit to alternating current is referred to as? Context: where a single prime denotes the real part and a double prime the imaginary part, Z() is the complex impedance with the dielectric present, Ccmplx() is the so-called complex capacitance with the dielectric present, and C0 is the capacitance without the dielectric. (Measurement "without the dielectric" in principle means measurement in free space, an unattainable goal inasmuch as even the quantum vacuum is predicted to exhibit nonideal behavior, such as dichroism. For practical purposes, when measurement errors are taken into account, often a measurement in terrestrial vacuum, or simply a calculation of C0, is sufficiently accurate.)
Ans: impedance

Extract the answer to the question from the following context. Question: What was the main goal of the Ottomans? Context: The Ottoman economic mind was closely related to the basic concepts of state and society in the Middle East in which the ultimate goal of a state was consolidation and extension of the ruler's power, and the way to reach it was to get rich resources of revenues by making the productive classes prosperous.

Extract the answer to the question from the following context. Question: HOw was the system viewed? Context: Windows 8 was released to a mixed critical reception. Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system was widely criticized for being potentially confusing and difficult to learn (especially when used with a keyboard and mouse instead of a touchscreen). Despite these shortcomings, 60 million Windows 8 licenses have been sold through January 2013, a number which included both upgrades and sales to OEMs for new PCs.
Ans: mixed critical reception
