QUES: A resin used for making non-wrinkle shirts releases formaldehyde, which could cause contact dermatitis for some people; no disclosure requirements exist, and in 2008 the U.S. Government Accountability Office tested formaldehyde in clothing and found that generally the highest levels were in non-wrinkle shirts and pants. In 1999, a study of the effect of washing on the formaldehyde levels found that after 6 months after washing, 7 of 27 shirts had levels in excess of 75 ppm, which is a safe limit for direct skin exposure.

How many ppm is a safe limit for direct skin exposure to formaldehyde?

QUES: Modern font technology provides a means to address the practical issue of needing to depict a unified Han character in terms of a collection of alternative glyph representations, in the form of Unicode variation sequences. For example, the Advanced Typographic tables of OpenType permit one of a number of alternative glyph representations to be selected when performing the character to glyph mapping process. In this case, information can be provided within plain text to designate which alternate character form to select.

QUES: In response to concerns that clubs were increasingly passing over young English players in favour of foreign players, in 1999, the Home Office tightened its rules for granting work permits to players from countries outside of the European Union. A non-EU player applying for the permit must have played for his country in at least 75 per cent of its competitive 'A' team matches for which he was available for selection during the previous two years, and his country must have averaged at least 70th place in the official FIFA world rankings over the previous two years. If a player does not meet those criteria, the club wishing to sign him may appeal.

Could a club appeal a requirement?
