Answer:
Picture a cute little glowing kitten
Step-by-step explanation:
Descriptive details help us more vividly imagine what is written, allowing us to feel as if we are a part of the scene.
Descriptive details in this passage don't help us understand how Gomez gets her results of why she makes the kitten glow. That is not their purpose. They help us visualize, not understand. This is why the two last options are the only ones we should consider. However, the passage tells us about a kitten, which is why the third option is incorrect. There are no adult cats in the scene.
This is why the last option is the correct one - the descriptive details in the passage help us picture a cute little glowing kitten.
