Input: Consider Input: Certain genera of Gram-positive bacteria, such as Bacillus, Clostridium, Sporohalobacter, Anaerobacter, and Heliobacterium, can form highly resistant, dormant structures called endospores. In almost all cases, one endospore is formed and this is not a reproductive process, although Anaerobacter can make up to seven endospores in a single cell. Endospores have a central core of cytoplasm containing DNA and ribosomes surrounded by a cortex layer and protected by an impermeable and rigid coat. Dipicolinic acid is a chemical compound that composes 5% to 15% of the dry weight of bacterial spores. It is implicated as responsible for the heat resistance of the endospore.

Output: What are highly resistant dormant structures of certain gram-positive bacteria called?


Input: Consider Input: An illustrative example of official involvement in organized crime can be found from 1920s and 1930s Shanghai, where Huang Jinrong was a police chief in the French concession, while simultaneously being a gang boss and co-operating with Du Yuesheng, the local gang ringleader. The relationship kept the flow of profits from the gang's gambling dens, prostitution, and protection rackets undisturbed.[citation needed]

Output: When was Jinrong a police chief in this area?


Input: Consider Input: On 15 September the Luftwaffe made two large daylight attacks on London along the Thames Estuary, targeting the docks and rail communications in the city. Its hope was to destroy its targets and draw the RAF into defending them, allowing the Luftwaffe to destroy their fighters in large numbers, thereby achieving an air superiority. Large air battles broke out, lasting for most of the day. The first attack merely damaged the rail network for three days, and the second attack failed altogether. The air battle was later commemorated by Battle of Britain Day. The Luftwaffe lost 18 percent of the bombers sent on the operations that day, and failed to gain air superiority.


Output: On September 15 the Luftwaffe made daylight raids on what target in London?
