[EX Q]: Passage: The Late Jurassic spans from 163 million to 145 million years ago. The Late Jurassic featured a massive extinction of sauropods and Ichthyosaurs due to the separation of Pangaea into Laurasia and Gondwana in an extinction known as the Jurassic-Cretaceous extinction. Sea levels rose, destroying fern prairies and creating shallows in its wake. Ichthyosaurs went extinct whereas sauropods, as a whole, did not die out in the Jurassic; in fact, some species, like the Titanosaurus, lived up to the K-T extinction. The increase in sea-levels opened up the Atlantic sea way which would continue to get larger over time. The divided world would give opportunity for the diversification of new dinosaurs. Question: What did the separation of Pangaea cause to become extinct?
[EX A]: sauropods and Ichthyosaurs

[EX Q]: Passage: The MC controls the conferencing while it is active on the signaling plane, which is simply where the system manages conferencing creation, endpoint signaling and in-conferencing controls. This component negotiates parameters with every endpoint in the network and controls conferencing resources. While the MC controls resources and signaling negotiations, the MP operates on the media plane and receives media from each endpoint. The MP generates output streams from each endpoint and redirects the information to other endpoints in the conference. Question: What controls the conferencing while its active on the signaling plane?
[EX A]: The MC

[EX Q]: Passage: After World War II Hudson's realized that the limited parking space at its downtown skyscraper would increasingly be a problem for its customers. The solution in 1954 was to open the Northland Center in nearby Southfield, just beyond the city limits. It was the largest suburban shopping center in the world, and quickly became the main shopping destination for northern and western Detroit, and for much of the suburbs. By 1961 the downtown skyscraper accounted for only half of Hudson's sales; it closed in 1986. The Northland Center Hudson's, rebranded Macy's in 2006 following acquisition by Federated Department Stores, was closed along with the remaining stores in the center in March 2015 due to the mall's high storefront vacancy, decaying infrastructure, and financial mismanagement. Question: What was the store called in Southfield?
[EX A]:
Northland Center
