When a green-backed female heron saw some minnows swimming around in a pond, she came up with a way to catch them. First, she found a twig and broke it into small pieces. Then, she took it to the pond and put it in the water. She even moved it to a place in the pond where it would attract the minnows. Finaly, when the minnows swam over to the twig, she was able to catch one for her lunch. This shows that/how the heron was able to make use of a tool.
It seems to me that both "that" and "how" fit in the above, but I'm not very sure. If yes, do they mean about the same to you? Thanks.
