A passage is given below followed by several conclusions which can be drawn from the facts stated in the passages. You have to examine each inference separately in the context of the passage, decide upon its truth or falsity, and choose the conclusion that best supports the passage. 

Physics is pure science that seeks to understand the behaviour of matter without regard to whether it will afford any practical benefit. Engineering is the correlative applied science in which physical theories are put to some specific use, such as building a bridge or a nuclear reactor. Engineers obviously rely heavily on the discoveries of physicists, but an engineer's knowledge of the world is not the same as the physicist's knowledge. In fact, an engineer's know-how will often depend on physical theories that are false from the point of view of pure physics. There are some reasons for this. First, false theories in the purest and strictest sense are sometimes very good approximations to the true ones and often have the added virtue of being much easier to work with. Second, sometimes the true theories apply only under highly idealized conditions, which can only be created under controlled experimental situations. The engineer finds that in the real world, theories rejected by physicists yield more accurate predictions than the ones that they accept.

The passage, if true, is best supported by which of the following conclusions?
