Going through difficulties, some aboriginal people even started to create literature in their own languages.
Grammar books say the main clause and its subordinate clause have to have the same subject so that we can omit the subordinate clause's subject, like my Example 1. However, I think there are multiple interpretations for Example 1.
In my opinion, Example 1 means
"After some aboriginal people went through difficulties, they even started to create literature."
However, my guts feeling is telling me it means
"After aboriginal people(all aboriginal people in general) went through difficulties, some of them even started to create literature."
What do you guys think? Thanks in advance!
