Explanation:

Correct: In the tropical zone, trade winds blow from the east to the west. These winds push the ocean surface water westward. This leads to the upwelling of cold water from the deeper layers of the ocean in the eastern sections (like the coast of South America). Meanwhile, the warmer surface waters are accumulated in the western sections (like the western Pacific). As a result, the western sections of the tropical oceans are warmer than the eastern sections.

Incorrect: In the temperate zone, the westerlies don't necessarily make the eastern sections of the oceans warmer than the western sections in the same manner as trade winds do in the tropics. Factors like ocean currents play a significant role in determining the temperature distribution. For instance, the Gulf Stream warms the North Atlantic, making western Europe warmer than other regions at the same latitude.

Hence, the correct answer is "1 only".
