X: Medical research on animals should not be reduced in response to a concern for animals, because results of such research serve to avert human suffering.
X's Conclusion
We should still do research on animals because it helps avert human suffering, and greater weight should be given to human welfare over animal suffering.
X's Evidence
Research on animals helps avert human suffering.
Although there is some animal suffering, greater weight should be given to human welfare.
Evaluate
Speaker Y responds by offering an alternative method for research, (using computer modeling) that achieves the intended benefits without the negative consequences of animal suffering.
Goal
Look for any answer that matches. It might say that Y proposed an alternative method of doing research.
