A soviet citizen might think that their sacrifices were not really that big and that they're just praising themselves needlessly. This is because war was not fought on American soil so the American people did not really feel the terror of the war. Another one is the number of victims in the war and what was lost since the Soviets lost more than anyone else of all armies that participated in the war.
The correct answer is letter C
A congress is a meeting of people with common interests, which aims to address certain issues, communicate work, present proposals or exchange ideas. The congress can be a good occasion to resolve outstanding issues on the part of the assembly in question.
In general, a congress consists of the presentation of a project or a work proposal. As your intention is didactic or persuasive, it is essential that the speaker knows in depth the topics covered. The congress must have an introduction (to arouse the audience's interest), a central body (in which the message intended to be transmitted is developed) and a conclusion (which usually summarizes what is expressed in the central body).
It is important that the congress has an adequate audiovisual support that reinforces the concepts or that facilitates the understanding of the terms. For example: the speaker can lean on slides while speaking, take breaks to show short videos, etc.
At the end of the conference, it is necessary to reserve a space for questions or dialogue. The speaker should invite the audience and / or other stakeholders to ask questions, and should be clear in their responses. On the other hand, you should avoid all kinds of personal dialogues (those that can prevent the other people present from expressing themselves), and the ideal is to answer doubts and questions in general and establishing links with what has already been exposed / debated
