Quantum theory, although of tremendous scientific value, has nevertheless prompted debate among physicists. The debate arose because quantum theory addresses the peculiar properties of minute objects such as photons and electrons. While one type of experiment shows that these objects behave like particles, with well-defined trajectories through space, another demonstrates that, on the contrary, they behave waves, their peaks and troughs producing characteristic "interference" effects. However, scientists have failed to devise an experiment to demonstrate both behaviors simultaneously.
In the 1920s, two alternate interpretations of quantum theory attempted to resolve this apparently contradictory wave-particle duality. Physicist Niels Bohr argued that wave-particle properties are not contradictory, but complementary. Contrary to our intuition that an object continues to exist in some determined form even though we cannot perceive it, he concluded that the physical of a quantum object is actually undetermined before the object is observed via experiment.
Physicist Werner Heisenberg's "uncertainty principle," by contrast, postulated that we cannot precisely determine two complementary properties, such as position and momentum, of a quantum object simultaneously: if we measure an object's position with absolute certainty, then there is an infinite uncertainty in its momentum, and vice versa. He concluded that although we are limited in our ability to measure objects at the atomic and subatomic levels, their position and momentum are nonetheless defined all along.
It can be inferred from the passage that if scientists were able to measure the position and momentum of quantum objects precisely and simultaneously, then the

precisely determine two complementary properties, such as position and momentum, of a quantumobject simultaneously，uncertainty principle理论是假设complementary properties不能同时精确的测量到的，现在既然这个条件成立，那就是说这个理论本身不存在。选B
A. theory that the dual properties of quantum objects are complementary would be proven 无涉及
B. basic postulate of the uncertainty principle would be refuted
C. distinction between particle behavior and wave behavior would cease to exist 无涉及
D. debate about quantum theory among physicists would be unchanged 无涉及
E. trajectories of quantum objects through space would be more difficult to predict 第一段内容，题干无关
