What are the two approaches followed by classical physicists? (Select all that apply)

Choose at least one answer.

	a. Classical physicists think that their theories do not need to change.
	b. There is an effusive spirit of teamwork to bridge the two science approaches.
	c. The weird stuff of quantum physics, like non-locality and discontinuity, if it remains in the submicroscopic world and does not affect the macro world, then there is no need to worry about it.
	d. Newtonian physics uses the correspondence principle for the macro world; we can take neutron physics and use mathematics to get predictions and go on with life as usual.
