Problem: The noise-based speed is defined as the exposure that will lead to a given signal-to-noise ratio on individual pixels. Two ratios are used, the 40:1 ("excellent image quality") and the 10:1 ("acceptable image quality") ratio. These ratios have been subjectively determined based on a resolution of 70 pixels per cm (178 DPI) when viewed at 25 cm (9.8 inch) distance. The signal-to-noise ratio is defined as the standard deviation of a weighted average of the luminance and color of individual pixels. The noise-based speed is mostly determined by the properties of the sensor and somewhat affected by the noise in the electronic gain and AD converter.
How are the two ratios found?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The elections of 2010 resulted in a victory for the military-backed Union Solidarity and Development Party. Various foreign observers questioned the fairness of the elections. One criticism of the election was that only government sanctioned political parties were allowed to contest in it and the popular National League for Democracy was declared illegal. However, immediately following the elections, the government ended the house arrest of the democracy advocate and leader of the National League for Democracy, Aung San Suu Kyi, and her ability to move freely around the country is considered an important test of the military's movement toward more openness. After unexpected reforms in 2011, NLD senior leaders have decided to register as a political party and to field candidates in future by-elections.
What was the Burmese official decision concerning the legitimacy of National League for Democracy in 2010 ?
A: the popular National League for Democracy was declared illegal
