Some dictionaries say "the course of" can be used with "over," "in," "during," and "throughout." I'm wondering if there's any difference among these options.
For example, if event A happened throughout the course of event B, does that mean event A lasted as long as event B (or happened at various parts of event B), or event A happened at some point in the course of event B?
What about the other combinations, i.e. "during the course of, "in the course of," and "over the course of"?
