Hey there!
The answer would be what to do if someone falls overboard. Finding food is not that hard on a ship and probably not important. Washing the ship Hull is not for the passengers. Navigation lights is for the driver of the boat to use. If someone falls overboard, they could drown if they don’t know how to swim. This is very dangerous.
Yes blue makes people calmer because it’s a low color and makes people relaxed
It is because the “building” word that denotes infrastructures is a gerund. Gerunds are nouns that came from verbs + a suffix “ing". So in this case, “building” comes from the verb “built" (which implies that something is already done building something) + the “-ing”.
