Whereas heat transferred between the ocean and the atmosphere occurs more rapidly when the ocean is warmer than the air, it is slow when the ocean is colder.
A. Whereas heat transferred between the ocean and the atmosphere occurs more rapidly when the ocean is warmer than the air, it is slow when the ocean is colder.
B. Unlike the slow process of heat transfer between the ocean and the atmosphere when the ocean is colder than the air, heat transfers more rapidly when the ocean is warmer.
C. The transfer of heat between the ocean and the atmosphere is slow when the ocean is colder than the air and more rapid when the ocean is warmer.
D. Transferring heat between the ocean and the atmosphere occurs slowly when the ocean is colder than the air and more rapidly when it is warmer.
E. When the ocean is colder than the atmosphere, heat transferred between them occurs slowly, unlike the more rapid transfer occurring when the ocean is warmer.
A- Transferred - Past Tense, it is slow- Present Tense. Hence not parallel
B- "Unlike the slow process......, the rapid process...." not mentioned. Hence again not parallel
D- Last part of the sentence "...more rapidly when it is warmer", here we do not know "it" refers to air or water
E- "When" does not refer to any time- awkward and wordy. Also not parallel. Slowly/ rapidly is mentioned as slowly/ more rapid
C- is the correct answer. Simple tense, is parallel and not wordy
