Question
It is believed that algae grows faster in slow-flowing water. On the other hand, it is also argued that growth of algae causes hindrance to the flow of water. As more algae grows the speed at which water flows decreases.
Which of the following, if true, would most appropriately weaken the argument that growth of algae reduces speed of water?
