Which of the following is true of the daily surface energy balances for El Mirage (desert location at 35° N)and Pitt Meadows (Pacific coast location at 49° N)?
A)the expenditure for LE is very similar for both places.
B)the expenditure for G is very similar for both places.
C)the NET R for the desert surface and the moist vegetated surface are similar even though the values for individual terms in the heat balance equation may differ from one another.
D)the expenditure for H is very similar for both places.
E)there is no difference between the two locations with respect to the daily surface energy balances.

The question implies that the daily surface energy balances for El Mirage and Pitt Meadows have been compared, and asks which statement is true. Option A, B, D, and E can be ruled out because they state that the expenditure for LE, G, H, or the daily surface energy balances, respectively, are similar between the two locations. However, there is no such information or comparison given in the question. 
Option C is correct because it states that the NET R, which is the net radiation balance, for the desert surface and the moist vegetated surface are similar, although the values for individual terms in the heat balance equation may differ from one another. This is plausible because the desert location at 35° N and the Pacific coast location at 49° N would have different solar radiation inputs, but may show similar values for other components of the energy balance such as sensible and latent heat fluxes, and soil heat fluxes.
