question:
The Selective Service System is an independent agency of the United States government that maintains information on those potentially subject to military conscription. Virtually all male U.S. citizens and male immigrant non-citizens between the ages of 18 and 25 are required by law to have registered within 30 days of their 18th birthdays and must notify Selective Service within ten days of any changes to any of the information they provided on their registration cards, like a change of address. A 2010 Government Accountability Office report estimated the registration rate at 92% with the names and addresses of over 16.2 million men on file. However, the only audit of the addresses of registrants on file with the Selective Service System, in 1982, found that 20 -- 40% of the addresses on file with the Selective Service System for registrants in the age groups that would be drafted first were already outdated, and up to 75% for those registrants in their last year of potential eligibility to be drafted would be invalid.

question:
There are eleven official languages of South Africa: Afrikaans, English, Ndebele, Northern Sotho, Sotho, Swazi, Tsonga, Tswana, Venda, Xhosa and Zulu. Fewer than two percent of South Africans speak a first language other than an official one. Most South Africans can speak more than one language. Dutch and English were the first official languages of South Africa from 1910 to 1925. Afrikaans was added as a part of Dutch in 1925, although in practice, Afrikaans effectively replaced Dutch, which fell into disuse. When South Africa became a republic in 1961, the official relationship changed such that Afrikaans was considered to include Dutch, and Dutch was dropped in 1984, so between 1984 and 1994, South Africa had two official languages: English and Afrikaans.
