What unique accomplishment did ruben dario achieve at age 18

The unique accomplishment that Ruben Dario achieved at age 18 was that the government officials were so impressed with his writing that the president of congress awarded him with a scholarship to Europe, but later change that to Granada. Dario refused the scholarship as Granada and his home city of Leon had developed an historic rivalry. 

I really hope I helped :)
