Idea for the Q&A below: To answer this question, we should know that: Coverage was further enlarged in 1975 when Congress expanded the meaning of "tests or devices" to encompass any jurisdiction that provided English-only election information, such as ballots, if the jurisdiction had a single language minority group that constituted more than five percent of the jurisdiction's voting-age citizens.
Q: Context: In each of these amendments except for the 1992 amendments, Congress extended the special provisions that were tied to the coverage formula, such as the preclearance requirement. These provisions were extended for five years in 1970, seven years in 1975, and 25 years in both 1982 and 2006. In 1970 and 1975, Congress also expanded the coverage formula, supplementing it with new 1968 and 1972 trigger dates. Coverage was further enlarged in 1975 when Congress expanded the meaning of "tests or devices" to encompass any jurisdiction that provided English-only election information, such as ballots, if the jurisdiction had a single language minority group that constituted more than five percent of the jurisdiction's voting-age citizens. These expansions brought numerous jurisdictions into coverage, including many located outside of the South. To ease the burdens of the reauthorized special provisions, Congress liberalized the bailout procedure in 1982, allowing covered jurisdictions to escape coverage by upholding the voting rights of protected minorities and affirmatively acting to expand minority political participation.
