Answer:
The author developed the central idea of the passage by first stating the common perceptions that people have of social media influencers and then later stating in details what is actually obtainable.
Step-by-step explanation:
The main idea of the text is that the work done by social media influencers is not always glamorous as they also encounter challenges in the course of their work. Mike Aspinall, a 28-year-old blogger attests to this when he said that 'people look at bloggers and think that their life is as neat and Pinterest-worthy as their content but for every of his blog contents he has had to do some intensive research'. This central idea was developed by the author when he went from describing the common perceptions people have of influencers as people who have a very rosy life to stating that they have a life like everyone else. They also find some aspects of their jobs challenging.
