{'temperate zone': [0, 0, 0, 1], 'western sections': [0, 0, 0, 1], 'westerlies': [0, 0, 0, 1], 'tropical zone': [1, 0, 0, 3], 'eastern sections': [0, 0, 0, 1], 'oceans': [8, 1, 8, 19], 'trade winds': [2, 0, 0, 2]}

The correct answer is option 3, Both 1 and 2. Here`s why:

Statement 1: In the tropical zone, trade winds generally blow from east to west. As these winds blow, they move the warm surface water away from the coast causing upwelling of the cool nutrient-rich water from below along the eastern sections of oceans. This makes the western sections warmer. Therefore, the first statement is correct.

Statement 2: In the temperate zone, the westerlies (winds that blow from the west towards the east) move the warm surface water towards the coast on the eastern sections of oceans. This tends to make the eastern sections warmer compared to the western sections. Hence, the second statement is also correct.

So, the final verdict is that both statements are correct hence option 3 is the right answer.
