The problem: Answer a question about this article:
Later that summer, the Russians invaded Memel with 75,000 troops. Memel had one of the strongest fortresses in Prussia. However, after five days of artillery bombardment the Russian army was able to storm it. The Russians then used Memel as a base to invade East Prussia and defeated a smaller Prussian force in the fiercely contested Battle of Gross-Jägersdorf on 30 August 1757. However, it was not yet able to take Königsberg and retreated soon afterward. Still, it was a new threat to Prussia. Not only was Frederick forced to break off his invasion of Bohemia, he was now forced to withdraw further into Prussian-controlled territory. His defeats on the battlefield brought still more opportunist nations into the war. Sweden declared war on Prussia and invaded Pomerania with 17,000 men. Sweden felt this small army was all that was needed to occupy Pomerania and felt the Swedish army would not need to engage with the Prussians because the Prussians were occupied on so many other fronts.
What led to the defeat of the Prussians at Memel?
****
The answer: five days of artillery bombardment

On an international level the German DIN 4512 system has been effectively superseded in the 1980s by ISO 6:1974, ISO 2240:1982, and ISO 5800:1979 where the same sensitivity is written in linear and logarithmic form as "ISO 100/21°" (now again with degree symbol). These ISO standards were subsequently adopted by DIN as well. Finally, the latest DIN 4512 revisions were replaced by corresponding ISO standards, DIN 4512-1:1993-05 by DIN ISO 6:1996-02 in September 2000, DIN 4512-4:1985-08 by DIN ISO 2240:1998-06 and DIN 4512-5:1990-11 by DIN ISO 5800:1998-06 both in July 2002.
How is sensitivity shown in the ISO systems?
****
The answer:
in linear and logarithmic form as "ISO 100/21°"
