(A) the complexity of ordinary events means that simple laws do not apply to them.
(B) the complexity of ordinary events makes the simple underlying laws hard to figure out.
(C) there are not enough ordinary events to reveal simple laws.
(D) ordinary events are difficult to observe.
(A) the complexity of ordinary events means that simple laws do not apply to them.
No. Laws which are any good apply to everything.
(B) the complexity of ordinary events makes the simple underlying laws hard to figure out.
Yes. Complications like friction for example.
(C) there are not enough ordinary events to reveal simple laws.
No. The number of events is not the problem.
(D) ordinary events are difficult to observe.
No. We observe them all the time.
