Problem: Extract the answer to the question from the following context. Question: Which of the following is less related to today's mammals, Dimetrodon or sphenacodont pelycosaurs? Context: The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsidssometimes referred to as mammal-like reptilesbefore giving rise to the proto-mammals (Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of the non-avian dinosaurs 66 million years ago.

A: Dimetrodon

Context: On 27 August 2007, Royal Dutch Shell and Reitan Group, the owner of the 7-Eleven brand in Scandinavia, announced an agreement to re-brand some 269 service stations across Norway, Sweden, Finland and Denmark, subject to obtaining regulatory approvals under the different competition laws in each country. On April 2010 Shell announced that the corporation is in process of trying to find a potential buyer for all of its operations in Finland and is doing similar market research concerning Swedish operations.

Shell branded gas stations will be rebranded within maximum of five years from the acquisition and the number of gas stations is likely to be reduced. Until then the stations will operate under Shell brand licence.

Problem: Extract the answer to the question from the following context. Question: What was the original name of the fourth-oldest surviving European place name in the US? Context: While exploring inland along the northern coast of Florida in 1528, the members of the Narvaez expedition, including Alvar Nunez Cabeza de Vaca, found a Native American village near present-day Tallahassee, Florida whose name they transcribed as Apalchen or Apalachen [a.pala.tn]. The name was soon altered by the Spanish to Apalachee and used as a name for the tribe and region spreading well inland to the north. Panfilo de Narvaez's expedition first entered Apalachee territory on June 15, 1528, and applied the name. Now spelled "Appalachian," it is the fourth-oldest surviving European place-name in the US.

A: Apalchen or Apalachen

Problem: Extract the answer to the question from the following context. Question: What is the last great constructive nation that Shivaji created? Context: The post-Mughal era was dominated by the rise of the Maratha suzerainty as other small regional states (mostly late Mughal tributary states) emerged, and also by the increasing activities of European powers. There is no doubt that the single most important power to emerge in the long twilight of the Mughal dynasty was the Maratha confederacy. The Maratha kingdom was founded and consolidated by Chatrapati Shivaji, a Maratha aristocrat of the Bhonsle clan who was determined to establish Hindavi Swarajya. Sir J.N. Sarkar described Shivaji as "the last great constructive genius and nation builder that the Hindu race has produced". However, the credit for making the Marathas formidable power nationally goes to Peshwa Bajirao I. Historian K.K. Datta wrote about Bajirao I:

A:
Maratha kingdom
