QUES: The eight member countries of the Warsaw Pact pledged the mutual defense of any member who would be attacked. Relations among the treaty signatories were based upon mutual non-intervention in the internal affairs of the member countries, respect for national sovereignty, and political independence.

QUES: The Philadelphia dialect, which is spread throughout the Delaware Valley and South Jersey, is part of Mid-Atlantic American English, and as such it is identical in many ways to the Baltimore dialect. Unlike the Baltimore dialect, however, the Philadelphia accent also shares many similarities with the New York accent. Thanks to over a century of linguistics data collected by researchers at the University of Pennsylvania, the Philadelphia dialect under sociolinguist William Labov has been one of the best-studied forms of American English.[f]
Who studies the accent at the University of Pennsylvania?

ANS: William Labov

QUES: While outer space provides the most rarefied example of a naturally occurring partial vacuum, the heavens were originally thought to be seamlessly filled by a rigid indestructible material called aether. Borrowing somewhat from the pneuma of Stoic physics, aether came to be regarded as the rarefied air from which it took its name, (see Aether (mythology)). Early theories of light posited a ubiquitous terrestrial and celestial medium through which light propagated. Additionally, the concept informed Isaac Newton's explanations of both refraction and of radiant heat. 19th century experiments into this luminiferous aether attempted to detect a minute drag on the Earth's orbit. While the Earth does, in fact, move through a relatively dense medium in comparison to that of interstellar space, the drag is so minuscule that it could not be detected. In 1912, astronomer Henry Pickering commented: "While the interstellar absorbing medium may be simply the ether, [it] is characteristic of a gas, and free gaseous molecules are certainly there".
