Some potential anticancer drugs work by depriving growing tumors of needed blood vessels. The creation of blood vessels is called angiogenesis, and the experimental drugs work by inhibiting this process. The same drugs have been found to prevent obesity in rodents.

Summary
Some anticancer drugs work by depriving tumors of needed blood vessels. The drugs work by prohibiting angiogenesis, which is the creation of blood vessels. The same drugs have been discovered to prevent obesity in rodents.

Strongly Supported Conclusions
Angiogenesis is necessary for fat cells to grow.

A
The cells in tumors are more similar in structure to fat cells than to other cells in the body.
This answer is unsupported. We don’t know what the structure is of any kind of cell.
B
Drugs that inhibit angiogenesis would probably enable obese humans to lose weight.
This answer is unsupported. We don’t know if these drugs would probably cause obese humans to lose weight. We only know that the drugs have been found to prevent obesity in rodents.
C
Fat tissue depends on angiogenesis in order to grow.
This answer is strongly supported. Since the drugs prevent obesity in rodents, the drugs probably do this by inhibiting angiogenesis.
D
Rodents with cancer are more likely to be obese than healthy rodents.
This answer is unsupported. We don’t know anything about rodents with cancer.
E
Drugs that inhibit angiogenesis also prevent absorption of vital nutrients.
This answer is unsupported. We don’t know if the drugs have any other effects besides inhibiting angiogenesis.
