Eichmann trial was different in several ways. The public could, for the first time, watch coverage of the trial on television. The Eichmann trial brought the true scope of the Holocaust into public focus, filling the pages of newspapers with the stories of Holocaust survivors. While previous trials, including the Nuremberg Trials, had focused primarily on documentary evidence, the Eichmann trial called Holocaust survivors to the stand to share their personal experiences, with approximately 100 survivors taking the stand and testifying during the trial, which lasted from April 1960 until August 1961.
The correct answer is "protection".
In feudal society, a vassal was a person invested with a fief for which they had to povide services to a lord. First, a feudal contract was made, and under that contract, the lord was bound to provide the vassal with the fief, i.e. to provide protection and to do him justice in court. In return the Lord could demand the services which were attached to the fief, and these could include all kinds of services - military, administrative etc.
