In turn, Chairman Hua Guofeng visited Yugoslavia in 1979. In 1978, Tito traveled to the U.S. During the visit strict security was imposed in Washington, D.C. owing to protests by anti-communist Croat, Serb and Albanian groups.

Input: Read this: Another example is the practice of compulsory licensing, which is where the law forbids copyright owners from denying a license for certain uses of certain kinds of works, such as compilations and live performances of music. Compulsory licensing laws generally say that for certain uses of certain works, no infringement occurs as long as a royalty, at a rate determined by law rather than private negotiation, is paid to the copyright owner or representative copyright collective. Some fair dealing laws, such as Canada's, include similar royalty requirements.
Question: What aren't two examples of this licensing?

Output: unanswerable

Input: Read this: The solution was automation, in the form of a mechanical computer, the Kerrison Predictor. Operators kept it pointed at the target, and the Predictor then calculated the proper aim point automatically and displayed it as a pointer mounted on the gun. The gun operators simply followed the pointer and loaded the shells. The Kerrison was fairly simple, but it pointed the way to future generations that incorporated radar, first for ranging and later for tracking. Similar predictor systems were introduced by Germany during the war, also adding radar ranging as the war progressed.
Question: What did the Predictor calculate after it was pointed at a target?

Output:
the proper aim point automatically
