Input: Question: What dinosaurs migrated across West Suffield Mountain? Passage 1:West Suffield Mountain, like much of the Metacomet Ridge, is composed of basalt, also called traprock, a volcanic rock. The mountain formed near the end of the Triassic Period with the rifting apart of the North American continent from Africa and Eurasia. Lava welled up from the rift and solidified into sheets of strata hundreds of feet thick. Subsequent faulting and earthquake activity tilted the strata, creating the cliffs and ridgeline of West Suffield Mountain. Hot, dry upper slopes, cool, moist ravines, and mineral-rich ledges of basalt talus produce a combination of microclimate ecosystems on the mountain that support plant and animal species uncommon in greater Connecticut. West Suffield Mountain is also an important raptor migration path. (See Metacomet Ridge for more information on the geology and ecosystem of West Suffield Mountain).
 Passage 2:Mandal was selected in Nepal Under-19s fourteen man squad in the 2008 Under-19 World Cup, making six Youth One Day International appearances in the tournament. In 2010, Mandal was selected in Nepal's fourteen man squad for the 2010 World Cricket League Division Five in February 2010, making his senior debut in the tournament in a controversial match against the United States. Both teams would progress to the final of the tournament, where Mandal made his second appearance of the tournament. In April of that year, he played for Nepal in the 2010 ACC Trophy Elite, making six appearances. Having gained promotion in the World Cricket League by winning Division Five earlier in 2010, Nepal played in the Division Four in August of that year, with Mandal selected as part of Nepal's fourteen man squad for the tournament, where he made seven appearances. In November 2010, he played for Nepal in the 2010 Asian Games, making three appearances against Hong Kong, the Maldives and Sri Lanka, though Nepal didn't progress far enough in the tournament for Mandal to become a medalist.
 Passage 3:She made her first film in 1924, and with her blonde hair, green eyes, delicate features, and good-natured demeanor, was cast in a string of supporting roles, where she was required to do very little but smile and look pretty. She proved herself capable of handling the small roles she was assigned, and over a period of time, she came to be taken seriously as an actress. By 1928, she was playing starring roles, achieving success in MGM's first talkie release, Alias Jimmy Valentine (1928) opposite William Haines, Lionel Barrymore, and Karl Dane. The following year, she appeared in the popular murder mystery The Thirteenth Chair, a role that offered her the chance to display her dramatic abilities as a murder suspect. At Fox that same year, she appeared in director Allan Dwan's now lost romantic adventure The Far Call opposite Charles Morton. The quality of her parts continued to improve as the decade turned, including a role as Robert Montgomery's sister in the prison drama The Big House (1930) with Chester Morris and Wallace Beery, for which Hyams once again received positive reviews. She then appeared in Surrender (1931) in which Warner Baxter and Ralph Bellamy desperately competed for her attention.
