There is a fishing trawler with a ladder leaning against a wall in the harbour. There are 5oars and two fishing nets in the traw
ler. The distance between two consecutive steps on the ladder is 1 meter. If the waves lashing against the wall rise a half meter in every half hour, in how much time will 6 steps of the ladder get under the waves???
I am not the most experienced in this area. Though, my best guess would be A. Many soul musicians have background vocalists. They are the group of people in the background of a performance singing the same song but in a different tune. They are additional sounds and are not necessarily needed within a performance.
