premise: In Old Havana, hundreds of children marched around the Parque Central chanting ``We will save Elian!'' A small group of girls wore construction paper handcuffs -- an apparent reference to the government's characterization of Elian's retention in the United States as a ``kidnapping.''
  Fidel Castro's government has been using such traditional political events -- along with other rallies almost every day -- to draw attention to the case of Elian, who was rescued Nov. 25 while clinging to an inner tube. His mother and 10 others died at sea while trying to reach the United States.
  For the past two months, Elian's father has demanded that the boy be returned to him in Cuba, and the U.S. government has said that father and son should be reunited.
   Why is Castro's government holding rallies?
hypothesis: to draw attention to the case of Elian
