Question

which evidence from the text supports the inference that cancer is caused by cells growing when they shouldnt be?
\many types of cancer can be cured, especially if they are discovered early.\
\pancreatic cancer usually causes weight loss and stomach and back pain.\
\chemotherapy... uses medication to keep cancer cells from growing.\
\if the cancer is in only one place, doctors can often remove it with surgery.\
none of the above

Explanation:

To support the inference that cancer is caused by cells growing when they shouldn't be, we need evidence linking cancer to uncontrolled cell growth. Let's analyze each option:

• The first option is about cancer cure, not causation.
• The second option lists symptoms of pancreatic cancer, not causation.
• The third option says chemotherapy uses medication to keep cancer cells from growing. If cancer cells grow when they shouldn't, then a treatment to stop their growth supports the idea that uncontrolled growth is part of cancer's cause.
• The fourth option is about surgical removal, not causation.

Answer:

C. "Chemotherapy... uses medication to keep cancer cells from growing."
