Yassaie returned home to Iran for good in 1978
in the context  it says yassaie gained his science degree in U.K in 1979 then stayed in the U.K. to do his philosophy degree.                                                                                                                                                 So he couldn't have went home to Iran for good in 1978.                                                
So, the statement "Yassaie returned home to Iran for good in 1978 " , is definitely incorrect
