Problem: Like other South Slavic languages, Serbo-Croatian has a simple phonology, with the common five-vowel system and twenty-five consonants. Its grammar evolved from Common Slavic, with complex inflection, preserving seven grammatical cases in nouns, pronouns, and adjectives. Verbs exhibit imperfective or perfective aspect, with a moderately complex tense system. Serbo-Croatian is a pro-drop language with flexible word order, subjectverbobject being the default. It can be written in Serbian Cyrillic or Gaj's Latin alphabet, whose thirty letters mutually map one-to-one, and the orthography is highly phonemic in all standards.
From where does Serbo-Croatian derive its grammar?

Problem: Financial problems and a reduction in tourism led to Norfolk Island's administration appealing to the Australian federal government for assistance in 2010. In return, the islanders were to pay income tax for the first time but would be eligible for greater welfare benefits.

An agreement was finally signed in Canberra on 12 March 2015 to replace self-government with a local council but against the wishes of the Norfolk Island government.
