Input: Article: Early MPEG Layer III encoders used what is now called Constant Bit Rate (CBR). The software was only able to use a uniform bitrate on all frames in an MP3 file. Later more sophisticated MP3 encoders were able to use the bit reservoir to target an average bit rate selecting the encoding rate for each frame based on the complexity of the sound in that portion of the recording.

Now answer this question: Which early MPEG layer used CBR?

Output: Layer III

Input: Article: Parque Batlle (formerly: Parque de los Aliados, translation: "Park of the Allies") is a major public central park, located south of Avenida Italia and north of Avenue Rivera. Along with Parque Prado and Parque Rodo it is one of three large parks that dominate Montevideo. The park and surrounding area constitute one of the 62 neighbourhoods (barrios) of the city. The barrio of Parque Batlle is one of seven coastal barrios, the others being Buceo, Carrasco, Malvin, Pocitos, Punta Carretas, and Punta Gorda. The current barrio of Parque Battle includes four former districts: Belgrano, Italiano, Villa Dolores and Batlle Park itself and borders the neighbourhoods of La Blanqueada, Tres Cruces, Pocitos and Buceo. It has a high population density and most of its households are of medium-high- or high-income. Villa Dolores, a subdistrict of Parque Batlle, took its name from the original villa of Don Alejo Rossell y Rius and of Dona Dolores Pereira de Rossel. On their grounds, they started a private collection of animals that became a zoological garden and was passed to the city in 1919; in 1955 the Planetarium of Montevideo was built within its premises.

Now answer this question: What sub district of Parque Batlle took its name from the original villa of Don Alejo Rossell Y Rius?

Output: Villa Dolores

Input: Article: The islands are located about halfway between Hawaii and Australia, north of Nauru and Kiribati, east of the Federated States of Micronesia, and south of the U.S. territory of Wake Island, to which it lays claim. The atolls and islands form two groups: the Ratak (sunrise) and the Ralik (sunset). The two island chains lie approximately parallel to one another, running northwest to southeast, comprising about 750,000 square miles (1,900,000 km2) of ocean but only about 70 square miles (180 km2) of land mass. Each includes 15 to 18 islands and atolls. The country consists of a total of 29 atolls and five isolated islands.

Now answer this question: How many square kilometers of land do the Marshall Islands cover?

Output:
180
