Question: Passage: The Permian–Triassic extinction event, which was a prolonged event due to the accumulation of several extinction pulses, ended the dominance of the carnivores among the therapsids. In the early Triassic, all the medium to large land carnivore niches were taken over by archosaurs which, over an extended period of time (35 million years), came to include the crocodylomorphs, the pterosaurs, and the dinosaurs. By the Jurassic, the dinosaurs had come to dominate the large terrestrial herbivore niches as well. Question: What was the name of extinction level event that ended the dominance of the carnivores among therapsids?

Answer: Permian–Triassic


Question: Passage: At present, the branches Waal and Nederrijn-Lek discharge to the North Sea, through the former Meuse estuary, near Rotterdam. The river IJssel branch flows to the north and enters the IJsselmeer, formerly the Zuider Zee brackish lagoon; however, since 1932, a freshwater lake. The discharge of the Rhine is divided among three branches: the River Waal (6/9 of total discharge), the River Nederrijn – Lek (2/9 of total discharge) and the River IJssel (1/9 of total discharge). This discharge distribution has been maintained since 1709, by river engineering works, including the digging of the Pannerdens canal and since the 20th century, with the help of weirs in the Nederrijn river. Question: Where does the Ijssel branch flow?

Answer: IJsselmeer


Question: Passage: In 1968, Reprise planned to release a series of 78 rpm singles from their artists on their label at the time, called the Reprise Speed Series. Only one disc actually saw release, Randy Newman's I Think It's Going to Rain Today, a track from his self-titled debut album (with The Beehive State on the flipside). Reprise did not proceed further with the series due to a lack of sales for the single, and a lack of general interest in the concept. Guitarist & vocalist Leon Redbone released a promotional 78 rpm record in 1978 featuring two songs (Alabama Jubilee and Please Don't Talk About Me When I'm Gone) from his Champagne Charlie album. In 1980 Stiff Records in the United Kingdom issued a 78 by Joe "King" Carrasco containing the songs Buena (Spanish for "good," with the alternate spelling "Bueno" on the label) and Tuff Enuff. Underground comic cartoonist and 78 rpm record collector Robert Crumb released three discs with his Cheap Suit Serenaders in the 1980s. Question: Why did Reprise only release one 78 rpm vinyl?

Answer:
lack of sales for the single, and a lack of general interest
