" has aroused wide concern" Something has caused a large number of people to worry about this particular thing or situation. " has been brought into focus" means (figuratively) that something has been made clear and understandable. Examples: "The rise in the interest rate aroused a wide concern among the shareholders." " The reason for the rise in interest rate has been brought to focus."

An enormous difference. Just look up the words in a dictionary.

A very big difference!

"has aroused wide concern" 我覺得是激起大眾的迴響 "has been brought into focus" 則是前述的事情被帶入焦點 個人的一點淺見
