In response to the pressure on Hot AC, a new kind of AC format cropped up among American radio recently. The urban adult contemporary format (a term coined by Barry Mayo) usually attracts a large number of African Americans and sometimes Caucasian listeners through playing a great deal of R&B (without any form of rapping), gospel music, classic soul and dance music (including disco).
What style of singing is absent from R&B played on urban adult contemporary format stations?
rapping

Input: Age of Enlightenment
The most influential publication of the Enlightenment was the Encyclopedie, compiled by Denis Diderot and (until 1759) by Jean le Rond d'Alembert and a team of 150 scientists and philosophers. It was published between 1751 and 1772 in thirty-five volumes, and spread the ideas of the Enlightenment across Europe and beyond. Other landmark publications were the Dictionnaire philosophique (Philosophical Dictionary, 1764) and Letters on the English (1733) written by Voltaire; Rousseau's Discourse on Inequality (1754) and The Social Contract (1762); and Montesquieu's Spirit of the Laws (1748). The ideas of the Enlightenment played a major role in inspiring the French Revolution, which began in 1789. After the Revolution, the Enlightenment was followed by an opposing intellectual movement known as Romanticism.

Voltaire wrote Letters on the English in what year?
Output: 1733

Input: Article: Following the elections of 1973, the constitution of Swaziland was suspended by King Sobhuza II who thereafter ruled the country by decree until his death in 1982. At this point Sobhuza II had ruled Swaziland for 61 years, making him the longest ruling monarch in history. A regency followed his death, with Queen Regent Dzeliwe Shongwe being head of state until 1984 when she was removed by Liqoqo and replaced by Queen Mother Ntfombi Tfwala. Mswati III, the son of Ntfombi, was crowned king on 25 April 1986 as King and Ingwenyama of Swaziland.

Now answer this question: Who ruled Swaziland in the late 1970s?

Output: King Sobhuza II

Article: Since 1993, the Sodor and Man Diocesan Synod has had power to enact measures making provision "with respect to any matter concerning the Church of England in the Island". If approved by Tynwald, a measure "shall have the force and effect of an Act of Tynwald upon the Royal Assent thereto being announced to Tynwald". Between 1979 and 1993, the Synod had similar powers, but limited to the extension to the Isle of Man of measures of the General Synod. Before 1994, royal assent was granted by Order in Council, as for a bill, but the power to grant royal assent to measures has now been delegated to the lieutenant governor. A Measure does not require promulgation.

Question: Up until 1994, royal assent was given by whom?
Ans: Order in Council

Here is a question about this article: A watt balance is an instrument for comparing two powers, one of which is measured in SI watts and the other of which is measured in conventional electrical units. From the definition of the conventional watt W90, this gives a measure of the product KJ2RK in SI units, where RK is the von Klitzing constant which appears in the quantum Hall effect. If the theoretical treatments of the Josephson effect and the quantum Hall effect are valid, and in particular assuming that RK = h/e2, the measurement of KJ2RK is a direct determination of the Planck constant.
What is the answer to this question: What value does RK represent?
****
So... the von Klitzing constant which appears in the quantum Hall effect

Article: A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.

Question: What happens when sunlight shines on a solar balloon?
Ans:
the air inside is heated and expands causing an upward buoyancy force
