Final answer:
The tumor is likely to be found in the occipital lobe.
Step-by-step explanation:
If Amy has lost her senses of sight, hearing, and touch due to pressure on the brain, the tumor is likely to be found in the occipital lobe. The occipital lobe is responsible for visual processing, so if it is affected, it can result in loss of sight. However, it's important to note that other parts of the brain can contribute to visual function as well.
