Almost all of the composers who are described in music textbooks on classical music and whose works are widely performed as part of the standard concert repertoire are male composers, even though there has been a large number of women composers throughout the classical music period. Musicologist Marcia Citron has asked "[w]hy is music composed by women so marginal to the standard 'classical' repertoire?" Citron "examines the practices and attitudes that have led to the exclusion of women composers from the received 'canon' of performed musical works." She argues that in the 1800s, women composers typically wrote art songs for performance in small recitals rather than symphonies intended for performance with an orchestra in a large hall, with the latter works being seen as the most important genre for composers; since women composers did not write many symphonies, they were deemed to be not notable as composers. In the "...Concise Oxford History of Music, Clara Shumann  [sic] is one of the only  [sic] female composers mentioned." Abbey Philips states that "[d]uring the 20th century the women who were composing/playing gained far less attention than their male counterparts."

The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Geologists often prefer the term bitumen. Common usage often refers to various forms of asphalt/bitumen as "tar", such as at the La Brea Tar Pits. Another archaic term for asphalt/bitumen is "pitch".
What is a naming term for asphalt?
tar

In the 1970s, the United States began developing a new generation of reusable orbital spacecraft known as the Space Shuttle, and launched a range of unmanned probes. The USSR continued to develop space station technology with the Salyut program and Mir ('Peace' or 'World', depending on the context) space station, supported by Soyuz spacecraft. They developed their own large space shuttle under the Buran program. However, the USSR dissolved in 1991 and the remains of its space program were distributed to various Eastern European countries. The United States and Russia would work together in space with the Shuttle–Mir Program, and again with the International Space Station.
What year did the USSR disband?
1991
