Answer: when a writer points to a problem caused by social customs without explicitly challenging those customs.
A social commentary is the use of rhetorical devices in order to comment on the problems of society. This is usually a critique, and it is intended to promote change or to appeal to people's sense of justice. However, when this commentary is done subconsciously, the writer points towards the problem but does not explicitly challenge the customs.
Guessing at what word the question is asking about here. I'd say B - obstinacy means being stubborn or inflexible, which doesn't apply here.
I think the primary audience of the journal is people who follow the trends. The writer explained how fashion affected people's perspective on dressing up and following the popular trends. Fashion played a significant role in the 60s. Fashion made people want to feel accepted in that particular group of individuals.
