Many People Think That Water Draining from a Sink Rotates

Multiple Choice

Many people think that water draining from a sink rotates in a particular direction due to something called the Coriolis effect due to the rotation of the earth. Furthermore, such people frequently argue that the direction is reversed in opposite hemisphere. In reality, the Coriolis effect in that situation is so small
it has virtually no effect on the direction water drains from a sink or toilette. The drainage direction is related to the shape of the sink bowl or the direction water flushes into a toilette.
-Which characteristic of "bad science" related to draining water is most prevalent in this passage?

A) Attack on the scientist, not the science.
B) Arguing from authority.
C) Confusing cause and effect.
D) The use of bad statistics.
