A boolean path operation, such as Path menu > Difference could accomplish that. Although note that most of those circle objects are clones, and you'll need to break their links to their parent, so that they are paths, before the operation will work. Oh, and also, you'll need to use Path menu > Combine, to combine the 7 circles which make up a single unit. Do that for all the clones, and then you'll be ready to perform the Difference on them.
Generally, the path operations work on only 2 objects at a time. So you would duplicate one (after uncloning and combining), and select another one that overlaps, and perform the operation. Then repeat that until all are done.
If you had a file with many, many more objects, there are extenstions that will perform multiple operations at once, rather than one at a time. But for this file, I don't think it would save very much time.
By the way, this forum is no longer taking support questions - not since the new forum opened on the Inkscape website, last August:
