Question

which best explains how fiber - optic technology benefits the field of medicine?

• it allows doctors to view internal body structures to help them diagnose illnesses.
• it helps surgeons make more accurate repairs to broken blood vessels.
• it allows doctors to magnify cells so they can identify unhealthy cells that cause cancer.
• it helps surgeons make cuts that are smaller and less painful than traditional methods.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Fiber - optic technology in medicine (like endoscopes with fiber optics) enables doctors to view internal body structures non - invasively, aiding diagnosis. This matches the use of fiber - optic for internal visualization.
• Option 2: Repairing broken blood vessels is more related to techniques like angioplasty or other vascular repair methods, not a primary use of fiber - optic tech.
• Option 3: Magnifying cells to identify cancerous cells is done with microscopes (optical or electron), not fiber - optic tech.
• Option 4: Making smaller, less painful cuts is related to minimally invasive surgical tools like laparoscopes (which can use fiber optics, but the main benefit of fiber - optic in medicine is visualization for diagnosis, and the description here is more about the result of minimally invasive surgery rather than the core benefit of fiber - optic tech). So the best explanation is the first option.

Answer:

A. It allows doctors to view internal body structures to help them diagnose illnesses.
