Answer
Brief Explanations:
Medical inspections were one of the many challenges immigrants faced. It shows that there were multiple hurdles (like this inspection process) they had to go through. Just because there were medical inspections doesn't mean most came with health conditions (it could be a precaution), they didn't come for health care (they came for various other reasons like work, a new life etc.), and not all were rejected (the inspection was a step, not a guarantee of rejection).
Answer:
Immigrants faced several different challenges.
