The yellow beams in the model represent equal amounts of radiation coming from the Sun. A. All parts of Earth’s surface get sunlight at the same angle and of the same intensity.
B. The regions near the poles get the most-intense and most-direct sunlight.
C. Sunlight is more spread out at the poles than at the equator.
D. Higher latitudes get less-direct sunlight than latitudes near the equator.

PLEASE HELP ME!!

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
