Input: Read this: Influences also came to her from the art world, most notably through the works of Mexican artist Frida Kahlo. The music video of the song "Bedtime Story" featured images inspired by the paintings of Kahlo and Remedios Varo. Madonna is also a collector of Tamara de Lempicka's Art Deco paintings and has included them in her music videos and tours. Her video for "Hollywood" (2003) was an homage to the work of photographer Guy Bourdin; Bourdin's son subsequently filed a lawsuit for unauthorised use of his father's work. Pop artist Andy Warhol's use of sadomasochistic imagery in his underground films were reflected in the music videos for "Erotica" and "Deeper and Deeper".
Question: Madonna collects whose painting?

Output: Tamara de Lempicka

Input: Read this: The use of alloys by humans started with the use of meteoric iron, a naturally occurring alloy of nickel and iron. It is the main constituent of iron meteorites which occasionally fall down on Earth from outer space. As no metallurgic processes were used to separate iron from nickel, the alloy was used as it was. Meteoric iron could be forged from a red heat to make objects such as tools, weapons, and nails. In many cultures it was shaped by cold hammering into knives and arrowheads. They were often used as anvils. Meteoric iron was very rare and valuable, and difficult for ancient people to work.
Question: What was the first man-made alloy used by humans?

Output: unanswerable

Input: Read this: World-renowned (and city-born) architect Santiago Calatrava produced the futuristic City of Arts and Sciences (Ciutat de les Arts i les Ciencies), which contains an opera house/performing arts centre, a science museum, an IMAX cinema/planetarium, an oceanographic park and other structures such as a long covered walkway and restaurants. Calatrava is also responsible for the bridge named after him in the centre of the city. The Music Palace (Palau De La Musica) is another noteworthy example of modern architecture in Valencia.
Question: Which of Calatrava's creations contains an IMAX theater?

Output: City of Arts and Sciences

Input: Read this: Paleoptera and Neoptera are the winged orders of insects differentiated by the presence of hardened body parts called sclerites, and in the Neoptera, muscles that allow their wings to fold flatly over the abdomen. Neoptera can further be divided into incomplete metamorphosis-based (Polyneoptera and Paraneoptera) and complete metamorphosis-based groups. It has proved difficult to clarify the relationships between the orders in Polyneoptera because of constant new findings calling for revision of the taxa. For example, the Paraneoptera have turned out to be more closely related to the Endopterygota than to the rest of the Exopterygota. The recent molecular finding that the traditional louse orders Mallophaga and Anoplura are derived from within Psocoptera has led to the new taxon Psocodea. Phasmatodea and Embiidina have been suggested to form the Eukinolabia. Mantodea, Blattodea, and Isoptera are thought to form a monophyletic group termed Dictyoptera.
Question: An insects hard body parts are called what?

Output:
sclerites
