Read the passage.


The science teacher is holding some sort of snail in the palm of her hand. She pokes it gently and says, “Can anyone tell me what this is?”



“That’s a periwinkle,” says Thanh, and in her mind’s eye, she sees so clearly the chart they were given yesterday of all the tide pool creatures. But the teacher shakes her head and says, “Look again.” Thanh still sees a periwinkle.



What does the phrase her mind’s eye refer to?

the teacher’s expectations


the teacher’s thoughts


Thanh’s curiosity


Thanh’s memory
