The viscosity, or thickness, of magma inside an active volcano can determine how hazardous the eruption will be for surrounding communities. But the viscosity of the magma can typically only be studied once the eruption has already happened. ------- seismologists still continue to put effort and resources into determining the magma viscosity before the eruption in hopes of better predicting the impact it might have.Which choice completes the text with the most logical transition?Therefore,eliminateBesides,eliminateNevertheless,eliminateSubsequently,

14)Seismologists Kaiqing Yuan and Barbara Romanowicz have proposed that the magma fueling Iceland's more than 30 active volcano systems emerges from deep within Earth. The great depths involved—nearly 3,000 km—mark Iceland's volcanoes as extreme outliers; ______ many of Earth's volcanoes are fed by shallow pockets of magma found less than 15 km below the surface.Which choice completes the text with the most logical transition?STRPRAEN-014consequently,in addition,indeed,nevertheless,
