Input: Read this: In early 1991, non-Arabs of the Zaghawa tribe of Sudan attested that they were victims of an intensifying Arab apartheid campaign, segregating Arabs and non-Arabs (specifically people of sub-Saharan African descent). Sudanese Arabs, who controlled the government, were widely referred to as practicing apartheid against Sudan's non-Arab citizens. The government was accused of "deftly manipulat(ing) Arab solidarity" to carry out policies of apartheid and ethnic cleansing.
Question: Who controlled the government?

Output: Sudanese Arabs

Input: Read this: The existence of literary and colloquial readings (), called thak-im (), is a prominent feature of some Hokkien dialects and indeed in many Sinitic varieties in the south. The bulk of literary readings (, bun-thak), based on pronunciations of the vernacular during the Tang Dynasty, are mainly used in formal phrases and written language (e.g. philosophical concepts, surnames, and some place names), while the colloquial (or vernacular) ones (, peh-thak) are basically used in spoken language and vulgar phrases. Literary readings are more similar to the pronunciations of the Tang standard of Middle Chinese than their colloquial equivalents.
Question: What are literary and colloquial readings called?

Output: thak-im

Input: Read this: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinumiridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems it is known that over such a timescale the many similar PtIr alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
Question: What alloy is the base unit of the kilogram made from?

Output: platinumiridium

Input: Read this: Between 1945 and 1989, the share of ethnic Estonians in the population resident within the currently defined boundaries of Estonia dropped to 61%, caused primarily by the Soviet programme promoting mass immigration of urban industrial workers from Russia, Ukraine, and Belarus, as well as by wartime emigration and Joseph Stalin's mass deportations and executions.[citation needed] By 1989, minorities constituted more than one-third of the population, as the number of non-Estonians had grown almost fivefold.
Question: What period did the amount of ethnic Estonians drop by 61%?

Output:
Between 1945 and 1989
