C. In 1991 the kingdom established a multiparty parliamentary system.
D. Nepal, long under the rule of hereditary prime ministers favoring a policy of isolation, remained closed to the outside world until a palace revolt in 1950 restored the crown's authority in 1951.
Correct Answer: (b) DACB
Solution:Sentence D will be the starting line as it contains the main idea of the parajumble i.e. a palace revolt in 1950 in Nepal. However, Sentence A states that the country gained admission to the United Nations in 1955. So, A will follow D. Further, Sentence C states that in 1991 the kingdom established a multiparty parliamentary system & Sentence B states that in 2008, however, after a decade long period of violence and turbulent negotiation with a strong Maoist insurgency, the monarchy was dissolved, and Nepal was declared a democratic republic. So, B will follow C. Going through the options, only option b has the correct sequence.
