Two objects of different masses are joined by a light rod.

Question

a) Id the moment of inertia about the center of mas the minimum or maximum and why?
b) If the two masses are 3kg and 5kg and the length of the rod is 2m, what are the moments of inertia of the system about an axis perpendicular to the rod, through the center of the rod and the center of mass?

Would the answer to part a be minimum?
And is part b asking me to find the moments of inertia about the x-axis and the y-axis??
Please help!! I have no idea what the question is even looking for let alone how I'm supposed to solve it! Thank you!
