A. a reasonably clear picture has emerged of the patterns
and causes of ocean currents.

In A, is the placement of words correct. Shouldnt it be 'a clear picture of the patterns and causes of ocean currents has emerged'? Is there a difference between the modified version and the version stated in the choice?

Both sound good. I usually ignore the 'of .... ' part,

a reasonably clear picture has emerged 'of ...'

a reasonably clear picture 'of ....' has emerged
