0,20,20,2,17,20,1

keywords: 

{'rotation axis': [0, 0, 1, 0], 'orbital plane': [0, 0, 1, 0], 'earth': [0, 1, 1, 1]}

The correct answer is option 3: Both 1 and 2.

Statement 1 states that the Earth`s rotation axis is not at 90° to its orbital plane, and this is correct. If the Earth`s rotation axis was at 90° to its orbital plane, we would not experience seasons.

Statement 2 states that the Earth`s rotation axis is inclined at 23.5°, and this is also correct. The Earth`s rotation axis is inclined relative to its orbital plane, which leads to the change in seasons as different parts of the Earth receive more or less sunlight throughout the year.

Therefore, both statements 1 and 2 are correct, and the correct answer is option 3.
