Answer
The magnetic field in region 1 is out of the page.
Work Step by Step
As the loop enters region 1, the magnitude of the magnetic flux through the loop increases. The induced current produces a magnetic field which opposes this change.
It is given in the problem that the induced current moves clockwise. By the right hand rule, this current produces a magnetic field that is into the page.
Therefore, the magnetic field in region 1 is out of the page.
