Article: Romila Thapar notes that the division into Hindu-Muslim-British periods of Indian history gives too much weight to "ruling dynasties and foreign invasions", neglecting the social-economic history which often showed a strong continuity. The division into Ancient-Medieval-Modern periods overlooks the fact that the Muslim conquests occurred gradually during which time many things came and went off, while the south was never completely conquered. According to Thapar, a periodisation could also be based on "significant social and economic changes", which are not strictly related to a change of ruling powers.[note 1]

Question: What type of conquests were gradual in nature?
Ans: Muslim conquests

Article: On January 21, 1990, Rukh organized a 300-mile (480 km) human chain between Kiev, Lviv, and Ivano-Frankivsk. Hundreds of thousands joined hands to commemorate the proclamation of Ukrainian independence in 1918 and the reunification of Ukrainian lands one year later (1919 Unification Act). On January 23, 1990, the Ukrainian Greek-Catholic Church held its first synod since its liquidation by the Soviets in 1946 (an act which the gathering declared invalid). On February 9, 1990, the Ukrainian Ministry of Justice officially registered Rukh. However, the registration came too late for Rukh to stand its own candidates for the parliamentary and local elections on March 4. At the 1990 elections of people's deputies to the Supreme Council (Verkhovna Rada), candidates from the Democratic Bloc won landslide victories in western Ukrainian oblasts. A majority of the seats had to hold run-off elections. On March 18, Democratic candidates scored further victories in the run-offs. The Democratic Bloc gained about 90 out of 450 seats in the new parliament.

Question: When had the Ukrainian Greek-Catholic Church been broken up by the Soviets?
Ans: 1946
