The "cold fusion" phenomenon may be attributed to experimental errors
mistakenly indicating an excess production of energy. Those theories explaining
cold fusion require revisions in existing theories, and scientific skepticism
Line requires that unless the experimental evidence justifies belief in these miracles,
(5) one must conclude that experimental errors are being misinterpreted as positive
proof of cold fusion’s possibility. One would expect half of all careful energy-
balance measurements in cold fusion experiments to indicate excess energy, and
about half to show an energy deficit, because experimental error spreads the
results around the expected outcome. The recent preponderance of results
(10) showing excess energy might indicate something new, but if one is deliberately
searching for excess energy, then one may be able to "optimize" a complicated
system to yield large amounts of apparent excess energy by fooling the
measurement apparatus somehow. Whether a given excess-heat result
represents a physical "miracle" or an experimental error is very difficult to
(15) determine if the amount of excess heat is small or if the fraction of excess power
to total input power is simply too low. [br] The passage suggests which of the following about the recent research mentioned in lines 9-13?
选项
A、It has solved one set of problems but has created another.
B、It has overemphasized method at the expense of obtaining interesting results.
C、It has failed to propose practical applications for cold fusion, even if the phenomenon is proven to exist.
D、It has relied upon an experimental method possibly geared toward producing false results.
E、It has provided considerable information on the possibility of cold fusion phenomenon but it has failed to produce innovative experimental apparatus.
