A positive point charge q is located off-center inside a conducting spherical shell.We know from
Gauss’s law that the total charge on the inner surface of the shell is −q. Is the surface charge density negative over the entire inner surface?
Or can it be positive on the far side of the inner surface if the point charge q is close enough to the shell so that it attracts enough negative charge to the near side? Justify your answer.

The author asks the reader to think about the electric field lines.
Why isn't it possible? I can have electric field lines like these:
