Article: Hunter-gatherer societies manifest significant variability, depending on climate zone/life zone, available technology and societal structure. Archaeologists examine hunter-gatherer tool kits to measure variability across different groups. Collard et al. (2005) found temperature to be the only statistically significant factor to impact hunter-gatherer tool kits. Using temperature as a proxy for risk, Collard et al.'s results suggest that environments with extreme temperatures pose a threat to hunter-gatherer systems significant enough to warrant increased variability of tools. These results support Torrence's (1989) theory that risk of failure is indeed the most important factor in determining the structure of hunter-gatherer toolkits.

Question: What does temperature impact on tool kits?
Ans: increased variability of tools

Article: With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterialsfor example, the sulfonamides, the quinolones, and the oxazolidinonesare produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]

Question: What are the type of antibiotics which are taken from still living things?
Ans: aminoglycosides

Article: In February 1853, the British government of Lord Aberdeen, the prime minister, re-appointed Stratford Canning as British ambassador to the Ottoman Empire.:110 Having resigned the ambassadorship in January, he had been replaced by Colonel Rose as charge d'affaires. Lord Stratford then turned around and sailed back to Constantinople, arriving there on 5 April 1853. There he convinced the Sultan to reject the Russian treaty proposal, as compromising the independence of the Turks. The Leader of the Opposition in the British House of Commons, Benjamin Disraeli, blamed Aberdeen and Stratford's actions for making war inevitable, thus starting the process which would eventually force the Aberdeen government to resign in January 1855, over the war.

Question: Who replaced Stratford Canning after he first resigned as British ambassador to the Ottoman Empire ?
Ans: Colonel Rose
