{'greenwich meridian': [0, 0, 0, 1], 'meridian': [0, 1, 2, 5], 'greenwich': [1, 0, 0, 0], 'world map': [1, 0, 2, 1], 'eastward direction': [0, 0, 1, 1], 'globe': [0, 0, 3, 2], 'hour': [5, 5, 11, 12], 'time': [2, 6, 15, 23], 'hours': [7, 2, 16, 9]}

Option 1 states that the time of the 15th meridian is the same as Greenwich. This option is incorrect because as we move eastward in the world, the time becomes ahead of Greenwich due to the rotation of the Earth. Therefore, the time of the 15th meridian cannot be the same as Greenwich.

Option 2 states that the time of the 15th meridian is 1 hour fast. This option is correct. When we count the meridians in an eastward direction starting with Greenwich (0), each meridian is approximately 15 degrees apart. Since there are 24 hours in a day and 360 degrees in a circle (the Earth`s rotation), each meridian represents a time difference of 1 hour. So, the 15th meridian, being 15 meridians east of Greenwich, will be 15 hours ahead, or 1 hour fast.

Option 3 states that the time of the 15th meridian is 1 hour slow. This option is incorrect because, as explained earlier, the time becomes ahead of Greenwich as we move eastward.

Option 4 states that the time of the 15th meridian is 12 hours fast. This option is incorrect because the time difference between
