Which of the following most logically completes the passage? When the ocean is calm, its surface absorbs much of the sunlight reaching it and thus heats up. In windy conditions, however, waves develop and their white crests reflect much of the incoming sunlight, resulting in much less heating. Until recently, computer models designed to predict global temperature fluctuations did not take into account the effect of whitecaps on ocean temperatures. Nonetheless, factoring that effect in is unlikely to affect predictions very much, because __________. A. windy conditions are most likely to occur when clouds, which are taken into account by the computer models, block much of the Sun’s light B. windy conditions are as likely to occur at night, when there is no incoming sunlight at all, as they are to occur during daylight C. certain regions of the world’s oceans experience windy conditions far more frequently than other regions do D. the computer models use increasingly accurate estimates of the magnitude of various factors that influence global temperatures E. waves reaching ocean shores typically have white crests even in calm conditions OA only after discussions.

IMHO, answer should be A. If whitecaps are formed only during cloudy conditions, the lack of heating from the sunlight has already been accounted for and hence taking the whitecaps into consideration would not produce much of an effect. Kudos Please... If my post helped.

OA only after discussions. I think its A...because if the ocean waves or white crest develop in cloudy conditions, then there is no sun rays to reflect. This means that computer's predicted temp and the real temp will be equal.

OA only after discussions. Hey I think its B A says the program takes into consideration the clouds, which block the sun's rays....We do not know to what % the white crest affect the themp variatiaons.. hence we cannot say that A is the correct option. B clearly states that since windy condition occur at night when there is no sunlight hence IMO the correct answer.

OA only after discussions. The answer has to be A. B states that "windy conditions are as likely to occur at night, when there is no incoming sunlight at all, as they are to occur during daylight". It implies that windy conditions do take place during day time and thus whitecaps must form. One cannot neglect this factor because the whitecaps formed during day time will reflect much of the incoming signal, resulting in much less heating. A gives us one reason why whitecap factor may not be considered. Suppose the whitecaps are formed when there are cloudy conditions, then what will happen? Nothing. Since sunlight won't be able to reach the surface, so what are these whitecaps going to reflect? Absolutely nothing! Hence even if you consider the effect of whitecaps, the predictions may not be affected much.
