True or false: Earthquake early warning systems can predict when an earthquake will occur with great accuracy.

Seismologists are able to determine which places are at higher risk of earthquakes by studying the location of the Earth’s tectonic plates, since it is movement along these boundaries which causes the catastrophic events. They are much less confident, however, about when earthquakes will happen, and in fact, the USGS has never accurately predicted the timing of a major earthquake. In 1975, Chinese scientists used preceding foreshocks to make a prediction of a magnitude 7.5 earthquake in Haicheng, China, but the prediction was later deemed to be a fluke.Which choice best describes the function of the second sentence in the overall structure of the text?It explains how the work of the Chinese scientists was received by others in the field.eliminateIt presents the central discovery reported by the Chinese scientists.eliminateIt identifies the problem that Chinese scientists had hoped to solve but did not.eliminateIt describes a critical issue with the method used by the Chinese scientists in their research.
