Question for Nov 8, 2010

X is ubiquitous in USA, where it is easily recognized by its classic design using red and black colours. However, the ISO standard for X is very different from the American version. In fact, outside of USA (and a few other countries), this form of X is not considered to be an acceptable version, mainly because of the choice of its colours, and also because of its language specific nature.

In 1980, Japan submitted a design for X to ISO, which was approved over a very similar looking design submitted by USSR because of the extensive testing that was performed in Japan. Japan's design is in green and white, without any lettering, and is considered to be the form of X that is most easily recognizable by people. Even in places where Japan's design is not used, a variation of it is used. The American version, by contrast, has few takers outside the country. However, within USA, there has been strong opposition to the Japanese design and the codes within USA specify the use of the American design. There are signs, however, that acceptance of the Japanese design is slowly increasing, and that this might be seen alongside the American design till it eventually gains complete acceptance.

Identify X.

Edit: Added text to the question. The American version of X has red text against a black background, while the ISO standard shows a green figure against a white background. The reason the ISO standard is considered better is that it has no text, while the American version is helpful only to those who are familiar with English.
