Fermilab estimates that actual UFO landings happen about every 122 years, and any interplanetary UFO must have the energy signature of a nuclear missile. When a fully automated artificial intelligence encounters unforeseen stimuli, its response is unpredictable.

Which of the following conclusions can most properly be drawn, if the statements to the left are true, about a nuclear-missile defense system controlled by a fully automated artificial intelligence?

A. The system would respond incorrectly 122 years after becoming operational, and would start a war inadvertently.

B. The system would be destroyed by the energy from a UFO landing occurred in the Earth's atmosphere.
Unsupported; the passage says nothing about what is needed to destroy the system.

C. It would be impossible for the system to distinguish the energy of a UFO landing from the launch of a nuclear weapon.

D. Whether the system would respond incorrectly to the energy of a UFO landing would depend on the location of the landing.
Unsupported; the passage never considers location.

E. It is not certain what the system's response to the energy of a UFO landing would be, if its designers did not plan for such a contingency.
