Question

choose the statement that correctly describes the solar neutrino problem. detectors were only looking for one kind of neutrino and were not sensitive to other types of neutrinos. neutrinos move faster than the speed of light. the neutrinos detected were too large based on theoretical predictions. detectors were not sensitive enough to observe any types of neutrinos.

Explanation:

The solar - neutrino problem was that early detectors were only sensitive to one type of neutrino (electron - neutrinos) and were not able to detect other types (muon - neutrinos and tau - neutrinos). Neutrinos do not move faster than light, and the issue was not about the size of detected neutrinos or complete insensitivity of detectors to all neutrinos.

Answer:

Detectors were only looking for one kind of neutrino and were not sensitive to other types of neutrinos.
