Article: A census of sea life carried out during the International Polar Year and which involved some 500 researchers was released in 2010. The research is part of the global Census of Marine Life (CoML) and has disclosed some remarkable findings. More than 235 marine organisms live in both polar regions, having bridged the gap of 12,000 km (7,456 mi). Large animals such as some cetaceans and birds make the round trip annually. More surprising are small forms of life such as mudworms, sea cucumbers and free-swimming snails found in both polar oceans. Various factors may aid in their distribution – fairly uniform temperatures of the deep ocean at the poles and the equator which differ by no more than 5 °C, and the major current systems or marine conveyor belt which transport eggs and larval stages.

Question: When was the census of sea life carried out in Antarctica?
Ans: International Polar Year


Article: Insects were among the earliest terrestrial herbivores and acted as major selection agents on plants. Plants evolved chemical defenses against this herbivory and the insects, in turn, evolved mechanisms to deal with plant toxins. Many insects make use of these toxins to protect themselves from their predators. Such insects often advertise their toxicity using warning colors. This successful evolutionary pattern has also been used by mimics. Over time, this has led to complex groups of coevolved species. Conversely, some interactions between plants and insects, like pollination, are beneficial to both organisms. Coevolution has led to the development of very specific mutualisms in such systems.

Question: Insects formed mechanisms to shield against what?
Ans: plant toxins


Article: A fervent follower of the absolutist cause, Elío had played an important role in the repression of the supporters of the Constitution of 1812. For this, he was arrested in 1820 and executed in 1822 by garroting. Conflict between absolutists and liberals continued, and in the period of conservative rule called the Ominous Decade (1823–1833), which followed the Trienio Liberal, there was ruthless repression by government forces and the Catholic Inquisition. The last victim of the Inquisition was Gaietà Ripoli, a teacher accused of being a deist and a Mason who was hanged in Valencia in 1824.

Question: When was Elio killed?
Ans: 1822


Article: Many Sanskrit dramas also indicate that the language coexisted with Prakrits, spoken by multilingual speakers with a more extensive education. Sanskrit speakers were almost always multilingual. In the medieval era, Sanskrit continued to be spoken and written, particularly by learned Brahmins for scholarly communication. This was a thin layer of Indian society, but covered a wide geography. Centres like Varanasi, Paithan, Pune and Kanchipuram had a strong presence of teaching and debating institutions, and high classical Sanskrit was maintained until British times.

Question: For what did Brahmins use Sanskrit?
Ans:
scholarly communication
