question:  Why is Umluana speaking Dutch to Read and Rashid in the beginning?
context: Sergeant Rashid handed Premier Umluana the warrant. If Umluana noticed Read's gun, he didn't show it. Umluana was a small man with wrinkled brow, glasses and a mustache. Umluana turned back to Rashid a second too soon. Rashid judo chopped him and swung the inert body over his shoulders. Two men with rifles plunged into the gas; sighing, they fell to the floor in a catatonic trance. Two types of recruits are accepted by the UN Inspector Corps: those with a fanatic loyalty to the ideals of peace and world order, and those who are loyal to nothing but themselves. It was the home of factory workers, clerks, semiskilled technicians, all who do the drudge work of civilization and know they will never do more. Trained to use small arms and gas weapons, they guarded certain borders, bodyguarded diplomats and UN officials, even put down riots that threatened international peace. Read went through six months training on Madagascar. Rather than resign, he accepted punishment which assigned him to weeks of dull, filthy extra labor. Umluana took control of Belderkan in 1979. He began a propaganda war against neighboring South Africa, promising the liberation of that strife-torn land. Most Negro leaders, having just won representation in the South African Parliament, told him to liberate his own country. China called the uproar a vicious slur on a new African nation. Umluana was defying world law. They would enter Belderkan, arrest Umluana and try him by due process before the World Court. If the plan succeeded, mankind would be a long step farther from nuclear war. But then they would have spent hours flying over Africa, with Belderkan fighters in hot pursuit, other nations joining the chase and the world uproar gaining volume. By transmitter, if all went well, they could have Umluana in Geneva in an hour. From Miaka they would transmit to the Belderkan Preserve, a famous tourist attraction whose station could transmit to any point on the globe. "There's no military base near Miaka," Rashid said.
output:  It is the colonizer language of his own country.
options:  It is the colonizer language of his own country.  It's the language that the warrant is written in.  It is the language being used by everyone at the World Court event.  He wants to show off his ability to speak other languages.
