During the Soviet period, the policy toward the languages of the various other ethnic groups fluctuated in practice. Though each of the constituent republics had its own official language, the unifying role and superior status was reserved for Russian, although it was declared the official language only in 1990. Following the break-up of the USSR in 1991, several of the newly independent states have encouraged their native languages, which has partly reversed the privileged status of Russian, though its role as the language of post-Soviet national discourse throughout the region has continued.
In what year did other ethnic groups discourage native language?
A: unanswerable

James Liebman, a professor of law at Columbia Law School, stated in 1996 that his study found that when habeas corpus petitions in death penalty cases were traced from conviction to completion of the case that there was "a 40 percent success rate in all capital cases from 1978 to 1995." Similarly, a study by Ronald Tabak in a law review article puts the success rate in habeas corpus cases involving death row inmates even higher, finding that between "1976 and 1991, approximately 47 percent of the habeas petitions filed by death row inmates were granted." The different numbers are largely definitional, rather than substantive. Freedam's statistics looks at the percentage of all death penalty cases reversed, while the others look only at cases not reversed prior to habeas corpus review.
What does James Liebman reject?
A: unanswerable

In the 1980s and early 1990s, there was a significant movement in favor of the territory becoming a commonwealth, which would give it a level of self-government similar to Puerto Rico and the Northern Mariana Islands. However, the federal government rejected the version of a commonwealth that the government of Guam proposed, due to it having clauses incompatible with the Territorial Clause (Art. IV, Sec. 3, cl. 2) of the U.S. Constitution. Other movements advocate U.S. statehood for Guam, union with the state of Hawaii, union with the Northern Mariana Islands as a single territory, or independence.
Why would Guam becoming a commonwealth be so important?
A: would give it a level of self-government similar to Puerto Rico
