The problem: Answer a question about this article:
Her mature artistic statement was visible in True Blue (1986) and Like a Prayer (1989). In True Blue, she incorporated classical music in order to engage an older audience who had been skeptical of her music. Like a Prayer introduced live recorded songs and incorporated different genres of music, including dance, funk, R&B and gospel music. Her versatility was further shown on I'm Breathless, which consists predominantly of the 1940s Broadway showtune-flavoured jazz, swing and big band tracks. Madonna continued to compose ballads and uptempo dance songs for Erotica (1992) and Bedtime Stories (1994). Both albums explored element of new jack swing, with Jim Farber from Entertainment Weekly saying that "she could actually be viewed as new jack swing's godmother." She tried to remain contemporary by incorporating samples, drum loops and hip hop into her music. With Ray of Light, Madonna brought electronic music from its underground status into massive popularity in mainstream music scene.
Madonna brought which type of music to mainstream with Ray of Light?
****
The answer: electronic music

Among the oldest surviving examples of Nizam architecture in Hyderabad is the Chowmahalla Palace, which was the seat of royal power. It showcases a diverse array of architectural styles, from the Baroque Harem to its Neoclassical royal court. The other palaces include Falaknuma Palace (inspired by the style of Andrea Palladio), Purani Haveli, King Kothi and Bella Vista Palace all of which were built at the peak of Nizam rule in the 19th century. During Mir Osman Ali Khan's rule, European styles, along with Indo-Islamic, became prominent. These styles are reflected in the Falaknuma Palace and many civic monuments such as the Hyderabad High Court, Osmania Hospital, Osmania University, the State Central Library, City College, the Telangana Legislature, the State Archaeology Museum, Jubilee Hall, and Hyderabad and Kachiguda railway stations. Other landmarks of note are Paigah Palace, Asman Garh Palace, Basheer Bagh Palace, Errum Manzil and the Spanish Mosque, all constructed by the Paigah family.:1617

What century was Bella Vista Palace built?
Answer: 19th century

Problem: The theoretical difficulties arise from the fact that all of the methods except the X-ray crystal density method rely on the theoretical basis of the Josephson effect and the quantum Hall effect. If these theories are slightly inaccurate though there is no evidence at present to suggest they are the methods would not give accurate values for the Planck constant. More importantly, the values of the Planck constant obtained in this way cannot be used as tests of the theories without falling into a circular argument. Fortunately, there are other statistical ways of testing the theories, and the theories have yet to be refuted.
Other than the X-ray crystal density method, other methods rely on what two effects?
The answer is the following: the Josephson effect and the quantum Hall effect

The Feynman Lectures on Physics is perhaps his most accessible work for anyone with an interest in physics, compiled from lectures to Caltech undergraduates in 196164. As news of the lectures' lucidity grew, professional physicists and graduate students began to drop in to listen. Co-authors Robert B. Leighton and Matthew Sands, colleagues of Feynman, edited and illustrated them into book form. The work has endured and is useful to this day. They were edited and supplemented in 2005 with "Feynman's Tips on Physics: A Problem-Solving Supplement to the Feynman Lectures on Physics" by Michael Gottlieb and Ralph Leighton (Robert Leighton's son), with support from Kip Thorne and other physicists.
Which two of Feynman's colleagues helped put the lectures into book format?
Robert B. Leighton and Matthew Sands

Here is a question about this article: Sometimes people of mixed African-American and Native American descent report having had elder family members withholding pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, as censuses did not identify slaves by name before the American Civil War, meaning that most African Americans did not appear by name in those records. In addition, many white fathers who used slave women sexually, even those in long-term relationships like Thomas Jefferson's with Sally Hemings, did not acknowledge their mixed-race slave children in records, so paternity was lost.
What is the answer to this question: Who were not identified by name on the census before the civil war?
****
So...
slaves
