Words for discussion and argument

Ten minutes with the words an actual disagreement runs on: a discussion, an argument, the proof behind it, a proposal, a solution. You meet расправа, аргумент, доказ, предлог and решење, practice each one in the sentence it actually appears in, and hear a neutral question-answer pair said aloud before the unit's own dispute over a new shelter asks you to follow the same new-information-last logic yourself.
