The focus is on comparing the fluxes of neutrinos in two energy bands: 700-800 KeV and 800-900 KeV. The expected outcome is to find the ratio of these fluxes, which is given as 0.01 (10^-2), indicating that the flux in the lower energy band is significantly smaller than in the higher energy band due to the characteristics of neutrino production in the Sun."}
