The correct response is:
Scorpius is hunting Orion, so Orion is hiding from Scorpius during the summer.
In ancient Greek mythology, it is said that Scorpius was sent to hunt Orion, and therefore they are depicted as being in the sky at different times of the year to avoid each other. When Scorpius rises in the sky during the summer months, Orion sets and thus "hides" from Scorpius.
