time =15 s
velocity=
ft/s
velocity=2 ft/s
power = force
velocity
power=
power= 9000 lb ft/s
1 hp= 550 lb ft/s
power=
hp
The first one is d or the 4th answer choice and the second one is false. Hope this helps!

Explanation:
Alice need to know the secret key of carol to verify the carol's answer to Alice challenges.
Similarly it needs the secret key of Bob to verify bob's answer to Alice challenge (actually any of the three need others secret key for verify answer to challenge).
