21. The author implies that making a sharp division between subject and object in physics is

(B) still theoretically possible in the small-scale world of atoms and electrons
(C) possible in the case of observations involving the passage of a complete quantum
(D) no longer an entirely accurate way to describe observation of the universe(D)

(B) quanta of one-inch wavelength are not precisely analogous to yardsticks graduated in inches.
(C) Quanta of extremely long wavelength, in at least on e respect, resemble quanta of shorter wavelength.
(D) quanta of on-inch wavelength and quanta of extremely long wavelength do not differ only in their wavelengths.(B)
(E) quanta of one-inch wavelength must be measured by different standards than quanta of extremely long wavelength.
23. According to the passage, the quantum theory can be distinguished from previous theories of physics by its
(A) insistence on scrupulously precise mathematical formulations
(B) understanding of the inherent interrelationship of perceiver and perceived
(C) recognition of the need for sophisticated instruments of measurement
(D) emphasis on small-scale rather than on large-scale phenomena(B)
(E) regard for philosophical issues as well as for strictly scientific ones
