Analyse critique : Médias et fake news en anglais

Analyze the following social media post and provide a critical evaluation: 'Breaking News: A study shows that smartphone light reduces sleep quality by $50\%$. Experts claim that after just $3$ days of using a phone at night, your brain function drops by $25\%$. This is the absolute truth that the tech industry hides from you! You must share this to save your brain capacity.'

1. Explain why the use of statistics like $50\%$ and $25\%$ aims to manipulate the reader.
2. Identify the 'conspiracy' markers in the text.
3. Reformulate the core argument to reflect a neutral scientific perspective, assuming the variable $S$ represents sleep quality and $B$ represents brain function.
