Sex was used as an important element in the content and marketing the paper from the start, which Lamb believed was the most important part of his readers' lives. The first topless Page 3 model appeared on 17 November 1970, German-born Stephanie Rahn; she was tagged as a "Birthday Suit Girl" to mark the first anniversary of the relaunched Sun. A topless Page 3 model gradually became a regular fixture, and with increasingly risqué poses. Both feminists and many cultural conservatives saw the pictures as pornographic and misogynistic. Lamb expressed some regret at introducing the feature, although denied it was sexist. A Conservative council in Sowerby Bridge, Yorkshire, was the first to ban the paper from its public library, shortly after Page 3 began, because of its excessive sexual content. This decision was reversed after a sustained campaign by the newspaper itself lasting 16 months, and the election of a Labour-led council in 1971.
What did Lamb employ as an important theme from the beginning of the paper?
****
The answer: Sex


The problem: Answer a question about this article:
Bird migration is primarily, but not entirely, a Northern Hemisphere phenomenon. This is because land birds in high northern latitudes, where food becomes scarce in winter, leave for areas further south (including the Southern Hemisphere) to overwinter, and because the continental landmass is much larger in the Northern Hemisphere. In contrast, among (pelagic) seabirds, species of the Southern Hemisphere are more likely to migrate. This is because there is a large area of ocean in the Southern Hemisphere, and more islands suitable for seabirds to nest.
In which hemisphere does bird migration primarily happen?
****
The answer: Northern

Manifold vacuum can be used to drive accessories on automobiles. The best-known application is the vacuum servo, used to provide power assistance for the brakes. Obsolete applications include vacuum-driven windscreen wipers and Autovac fuel pumps. Some aircraft instruments (Attitude Indicator (AI) and the Heading Indicator (HI)) are typically vacuum-powered, as protection against loss of all (electrically powered) instruments, since early aircraft often did not have electrical systems, and since there are two readily available sources of vacuum on a moving aircraft—the engine and an external venturi. Vacuum induction melting uses electromagnetic induction within a vacuum.
Why are the Attitude indicator and heading indicator vacuum-powered?
****
The answer: protection against loss of all (electrically powered) instruments,


The problem: Answer a question about this article:
Most of these institutes award diplomas after three or three and a half years of education. The Institute of technology implementation (IUT from Instituto universitario de tecnologia on Spanish) began with the creation of the first IUT at Caracas, capital city of Venezuela, called IUT. Dr. Federico Rivero Palacio adopted the French "Institut Universitaire de Technologie"s system, using French personnel and study system based on three-year periods, with research and engineering facilities at the same level as the main national universities to obtain French equivalent degrees. This IUT is the first and only one in Venezuela having French equivalent degrees accepted, implementing this system and observing the high-level degrees some other IUT's were created in Venezuela, regardless of this the term IUT was not used appropriately resulting in some institutions with mediocre quality and no equivalent degree in France. Later, some private institutions sprang up using IUT in their names, but they are not regulated by the original French system and award lower quality degrees.
Who pioneered using the French system of technological education?

The answer:
Dr. Federico Rivero Palacio
