Article: During the listing process, economic factors cannot be considered, but must be " based solely on the best scientific and commercial data available." The 1982 amendment to the ESA added the word "solely" to prevent any consideration other than the biological status of the species. Congress rejected President Ronald Reagan's Executive Order 12291 which required economic analysis of all government agency actions. The House committee's statement was "that economic considerations have no relevance to determinations regarding the status of species."

Question: Because of the change to the Endangered Species Act in 1982, what is the only consideration for being listed as endangered?
Ans: the biological status of the species


Article: The consensus view in contemporary paleontology is that the flying theropods, or avialans, are the closest relatives of the deinonychosaurs, which include dromaeosaurids and troodontids. Together, these form a group called Paraves. Some basal members of this group, such as Microraptor, have features which may have enabled them to glide or fly. The most basal deinonychosaurs were very small. This evidence raises the possibility that the ancestor of all paravians may have been arboreal, have been able to glide, or both. Unlike Archaeopteryx and the non-avialan feathered dinosaurs, who primarily ate meat, recent studies suggest that the first avialans were omnivores.

Question: What are the closest relatives of flying theropods?
Ans: deinonychosaurs


Article: Grove Street Cemetery, a National Historic Landmark which lies adjacent to Yale's campus, contains the graves of Roger Sherman, Eli Whitney, Noah Webster, Josiah Willard Gibbs, Charles Goodyear and Walter Camp, among other notable burials. The cemetery is known for its grand Egyptian Revival gateway. The Union League Club of New Haven building, located on Chapel Street, is notable for not only being a historic Beaux-Arts building, but also is built on the site where Roger Sherman's home once stood; George Washington is known to have stayed at the Sherman residence while President in 1789 (one of three times Washington visited New Haven throughout his lifetime).

Question: What Beaux Arts structure on New Haven's Chapel Street was built on the site believed to formerly feature the home of Roger Sherman?
Ans: The Union League Club of New Haven building


Article: As a relatively small and isolated oceanic island, Norfolk has few land birds but a high degree of endemicity among them. Many of the endemic species and subspecies have become extinct as a result of massive clearance of the island's native vegetation of subtropical rainforest for agriculture, hunting and persecution as agricultural pests. The birds have also suffered from the introduction of mammals such as rats, cats, pigs and goats, as well as from introduced competitors such as common blackbirds and crimson rosellas.

Question: What is one reason that has caused many of the birds of Norfolk Island to become extinct?
Ans:
massive clearance of the island's native vegetation
