The document discusses the use of "while" and "when" to describe simultaneous actions in the past. It notes that "while" can introduce both a longer ongoing action and a shorter event. When describing two ongoing actions, the past continuous ("was/were + verb+ing") should be used for both. Similarly, "when" can also introduce both a longer ongoing action or shorter event, and the past continuous or past simple can be used depending on the context. The conclusion revises the initial definitions provided, clarifying that both "when" and "while" can be used with past continuous and past simple verbs.
