Problem: Given the question: Extract the answer to the question from the following context. Question: Which of the following is not featured on Melbourne's first public monument: Burke, Yarra or Wills? Context: The layout of the inner suburbs on a largely one-mile grid pattern, cut through by wide radial boulevards, and string of gardens surrounding the central city was largely established in the 1850s and 1860s. These areas were rapidly filled from the mid 1850s by the ubiquitous terrace house, as well as detached houses and some grand mansions in large grounds, while some of the major roads developed as shopping streets. Melbourne quickly became a major finance centre, home to several banks, the Royal Mint, and Australia's first stock exchange in 1861. In 1855 the Melbourne Cricket Club secured possession of its now famous ground, the MCG. Members of the Melbourne Football Club codified Australian football in 1859, and Yarra rowing clubs and "regattas" became popular about the same time. In 1861 the Melbourne Cup was first run. In 1864 Melbourne acquired its first public monumentthe Burke and Wills statue.

Yarra

Problem: Given the question: Extract the answer to the question from the following context. Question: What is the last European nationality mentioned? Context: In 1988, the civil rights leader Jesse Jackson urged Americans to use instead the term "African American" because it had a historical cultural base and was a construction similar to terms used by European descendants, such as German American, Italian American, etc. Since then, African American and black have often had parallel status. However, controversy continues over which if any of the two terms is more appropriate. Maulana Karenga argues that the term African-American is more appropriate because it accurately articulates their geographical and historical origin.[citation needed] Others have argued that "black" is a better term because "African" suggests foreignness, although Black Americans helped found the United States. Still others believe that the term black is inaccurate because African Americans have a variety of skin tones. Some surveys suggest that the majority of Black Americans have no preference for "African American" or "Black", although they have a slight preference for "black" in personal settings and "African American" in more formal settings.

Problem: Given the question: Extract the answer to the question from the following context. Question: What allowed rotation within Jedlik's prototypes? Context: In 1827, Hungarian physicist Anyos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings.

The answer is:
currents flowing through their windings
