Which of the following statements about Shi Huangdi's terracotta warriors is false?

Each warrior has unique characteristics, such as hairstyles and uniform details.

The warriors are life-size.

The warriors were created to guard Shi Huangdi's tomb.

Despite the "protection" of the warriors, robbers have pillaged Shi Huangdi's tomb.

The last one is false I believe. Very shortly after the site was uncovered, archaeologists came to excavate it, and the year after it was discovered they started building a museum on the site. Safe to say robbers probably would've had a hard time pillaging it when the whole archaeological community had their attention fixated on it.
