Here is a question about this article: Geologically, West Antarctica closely resembles the Andes mountain range of South America. The Antarctic Peninsula was formed by uplift and metamorphism of sea bed sediments during the late Paleozoic and the early Mesozoic eras. This sediment uplift was accompanied by igneous intrusions and volcanism. The most common rocks in West Antarctica are andesite and rhyolite volcanics formed during the Jurassic period. There is also evidence of volcanic activity, even after the ice sheet had formed, in Marie Byrd Land and Alexander Island. The only anomalous area of West Antarctica is the Ellsworth Mountains region, where the stratigraphy is more similar to East Antarctica.
What is the answer to this question: During what eras was the Antarctic Peninsula formed?

So... late Paleozoic and the early Mesozoic

Here is a question about this article: The music of the Romantic era, from roughly the first decade of the 19th century to the early 20th century, was characterized by increased attention to an extended melodic line, as well as expressive and emotional elements, paralleling romanticism in other art forms. Musical forms began to break from the Classical era forms (even as those were being codified), with free-form pieces like nocturnes, fantasias, and preludes being written where accepted ideas about the exposition and development of themes were ignored or minimized. The music became more chromatic, dissonant, and tonally colorful, with tensions (with respect to accepted norms of the older forms) about key signatures increasing. The art song (or Lied) came to maturity in this era, as did the epic scales of grand opera, ultimately transcended by Richard Wagner's Ring cycle.
What is the answer to this question: What is a name for an art song?

So... Lied

Here is a question about this article: Many historical sites exist throughout the city, including 59 properties listed on the National Register of Historic Places. Of these, nine are among the 60 U.S. National Historic Landmarks in Connecticut. The New Haven Green, one of the National Historic Landmarks, was formed in 1638, and is home to three 19th-century churches. Below one of the churches (referred to as the Center Church on-the-Green) lies a 17th-century crypt, which is open to visitors. Some of the more famous burials include the first wife of Benedict Arnold and the aunt and grandmother of President Rutherford B. Hayes; Hayes visited the crypt while President in 1880. The Old Campus of Yale University is located next to the Green, and includes Connecticut Hall, Yale's oldest building and a National Historic Landmark. The Hillhouse Avenue area, which is listed on the National Register of Historic Places and is also a part of Yale's campus, has been called a walkable museum, due to its 19th-century mansions and street scape; Charles Dickens is said to have called Hillhouse Avenue "the most beautiful street in America" when visiting the city in 1868.
What is the answer to this question: What tourist spot can be found directly underneath the New Haven Green?

So...
