{'local time': [0, 1, 1, 2], 'east': [0, 0, 2, 1], 'west': [11, 4, 16, 22], 'hours': [7, 2, 16, 9], 'difference': [1, 3, 4, 8]}

The question asks about the difference in local time between places located at 165° East and 165° West. To understand this, let`s consider how time zones work.

The Earth is divided into 24 time zones, with each zone representing a one-hour difference in time. As you move from East to West, the time increases due to the rotation of the Earth. Each time zone is approximately 15 degrees wide in longitude.

In this case, the two locations are 165 degrees apart, with one at 165° East and the other at 165° West. Since the Earth has 360 degrees of longitude, being 180 degrees apart means that they are on exactly the opposite sides of the Earth.

Since each time zone represents a one-hour difference, being on opposite sides of the Earth means that they are 12 hours apart in local time.

Therefore, the correct answer is option 2: 12 hours. The other options (0 hours, 22 hours, and 24 hours) are incorrect because they don`t align with the principles of time zones and the Earth`s rotation.
