Answer:
This line when the guard says, "We’ve been trying to keep the beast a secret, to avoid a panic".
Explanation:
When Minos was talking to Daedalus about containing the beast, he explains how the beast came about by saying, "I was supposed to sacrifice my prizebull to the god Poseidon. But I chose a lesserbull instead. Poseidon became so angry thathe cursed me with this beast. He even namedit the Minotaur—after me".
Then a guard now explains why it must be a secret, when he says, "We’ve been trying to keep the beasta secret, to avoid a panic".
The panic that will result when people know that there's a beast in the palace is what the King wishes to avoid.
