7. For a hard example with p_t close to zero, what is the focal modulating factor (1 − p_t)^gamma likely to do?
   • Drive the factor to zero
   • Turn the example into a positive label
   • Keep the factor relatively close to one so the example retains substantial loss weight
   • Replace the cross-entropy term with alpha
8. A dense detector has many easy background locations. What effect does focal loss aim to have on their combined training influence?
   • Increase their count by duplicating them
   • Remove all positive object examples
   • Make every example receive an identical loss
   • Reduce their dominance so training can focus more on sparse hard examples
