Read the passage and answer the question:

My School Things

Hi! My name is Mai. I love my school things because they are colorful and useful. My school bag is pink, and my best friend Lan’s bag is green. In my school bag, I have my books, notebooks, and a pencil case. My pencil case is blue, and inside, there are two pencils, a sharpener, and an eraser.

Lan’s pencil case is red, and she has three pens, a ruler, and a glue stick. Our friend Minh has a big black backpack. Inside his backpack, he keeps his books, a set square, and a small box of crayons. Sometimes, I borrow Lan’s ruler, and she uses my eraser. Minh often lends us his crayons when we do art projects. We always help each other when we need school supplies.

Whose school bag is pink?
