Article: The Paleozoic spanned from roughly 541 to 252 million years ago (Ma) and is subdivided into six geologic periods; from oldest to youngest they are the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Geologically, the Paleozoic starts shortly after the breakup of a supercontinent called Pannotia and at the end of a global ice age. Throughout the early Paleozoic, the Earth's landmass was broken up into a substantial number of relatively small continents. Toward the end of the era the continents gathered together into a supercontinent called Pangaea, which included most of the Earth's land area.

Question: The Permian is an example of what?
Ans: geologic periods


Article: Bacterial infections may be treated with antibiotics, which are classified as bacteriocidal if they kill bacteria, or bacteriostatic if they just prevent bacterial growth. There are many types of antibiotics and each class inhibits a process that is different in the pathogen from that found in the host. An example of how antibiotics produce selective toxicity are chloramphenicol and puromycin, which inhibit the bacterial ribosome, but not the structurally different eukaryotic ribosome. Antibiotics are used both in treating human disease and in intensive farming to promote animal growth, where they may be contributing to the rapid development of antibiotic resistance in bacterial populations. Infections can be prevented by antiseptic measures such as sterilizing the skin prior to piercing it with the needle of a syringe, and by proper care of indwelling catheters. Surgical and dental instruments are also sterilized to prevent contamination by bacteria. Disinfectants such as bleach are used to kill bacteria or other pathogens on surfaces to prevent contamination and further reduce the risk of infection.

Question: What kind of antibiotics are used for prevention of bacterial growth
Ans: bacteriostatic


Article: In the Colonial America of 1619, John Rolfe used negars in describing the slaves who were captured from West Africa and then shipped to the Virginia colony. Later American English spellings, neger and neggar, prevailed in a northern colony, New York under the Dutch, and in metropolitan Philadelphia's Moravian and Pennsylvania Dutch communities; the African Burial Ground in New York City originally was known by the Dutch name "Begraafplaats van de Neger" (Cemetery of the Negro); an early US occurrence of neger in Rhode Island, dates from 1625. Thomas Jefferson also used the term "black" in his Notes on the State of Virginia in allusion to the slave populations.

Question: Where were slaves shipped to from West Africa?
Ans: Virginia colony


Article: Following the events in Olympia, there were reports that China requested permission to deploy People's Liberation Army personnel along the relay route to protect the flame in Canberra. Australian authorities stated that such a request, if it were to be made, would be refused. Chinese officials labeled it a rumor. Australian police have been given powers to search relay spectators, following a call by the Chinese Students and Scholars Association for Chinese Australian students to "go defend our sacred torch" against "ethnic degenerate scum and anti-China separatists". Tony Goh, chairman of the Australian Council of Chinese Organisations, has said the ACCO would be taking "thousands" of pro-Beijing demonstrators to Canberra by bus, to support the torch relay. Zhang Rongan, a Chinese Australian student organising pro-Beijing demonstrations, told the press that Chinese diplomats were assisting with the organization of buses, meals and accommodation for pro-Beijing demonstrators, and helping them organise a "peaceful show of strength". Foreign Minister Stephen Smith said Chinese officials were urging supporters to "turn up and put a point of view", but that he had no objection to it as long as they remained peaceful.

Question: Chinese Australian students were told to defend what against scum and separatists?
Ans:
sacred torch
