Passage Summary: Some cancer drugs stop tumors from growing by blocking the formation of new blood vessels, and these same drugs have been shown to stop mice from becoming obese.

Reasoning: Tumors require new blood vessels to grow, a process called angiogenesis, which certain experimental drugs can block; these same drugs also prevent obesity in rodents.

Analysis: Since this is a Most Strongly Supported question, we are looking for a logical inference that connects the two main facts. The stimulus links angiogenesis (blood vessel creation) to tumor growth and then mentions that drugs inhibiting this process also affect obesity. A strong inference would suggest that the development of obesity, much like the growth of tumors, may depend on the process of angiogenesis. Look for an answer that bridges the gap between blood vessel formation and weight gain.
