The right answer that fills the blank can be:

- One day when baby Mark was crawling around, he fell down the stairs. After the doctor examined him, Mark's parents learned that he had damaged the parietal lobe of the brain. Mark's parents were told to expect that he would have difficulty with walking.

Explanation:

The parietal lobe has so many functions under its charge that it is difficult to ensure a particular problem due to its injury, however, since it is an injury in a baby that so far crawls, taking into account that the parietal lobe is responsible for linking sensory of the ear, sight and touch, as well as spatial positioning, it is possible that the baby having a condition in the lobe may present problems to start walking, since it would affect his balance and his motor to move his legs and stand up.
