To add the daylength information for the North Pole and South Pole into Table 3.3, we will consider the table as it currently exists and then include the new information.

The current table is as follows:

| Location (approximate latitude) | February 16th | May 16th | August 16th | November 16th |
|-----------------------------------|---------------|----------|-------------|---------------|
| North Pole (90° N) | | | | |
| White Horse, Canada (60° N) | 8.78 | 16.81 | 15.36 | 7.09 |
| Tokyo, Japan (35° N) | 10.73 | 13.84 | 13.32 | 10.13 |
| Addis Ababa, Ethiopia (10° N) | 11.68 | 12.46 | 12.33 | 11.53 |
| Quito, Ecuador (0°) | 12.00 | 12.00 | 12.00 | 12.00 |
| Palmas, Brazil (10° S) | 12.32 | 11.54 | 11.67 | 12.47 |
| Canberra, Australia (35° S) | 13.27 | 10.16 | 10.68 | 13.87 |

We need to add the daylength information for the North Pole and South Pole based on the given data.

From the given information:
- For the North Pole:
- February 16th: 11.5 hours
- May 16th: 18.00 hours
- August 16th: 12.5 hours
- November 16th: 20.5 hours

- For the South Pole:
- February 16th: 0 hours (no daylight)
- May 16th: 0 hours (no daylight)
- August 16th: 24 hours (full daylight)
- November 16th: 24 hours (full daylight)

Now, updating the table including these data points:

| Location (approximate latitude) | February 16th | May 16th | August 16th | November 16th |
|-----------------------------------|---------------|----------|-------------|---------------|
| North Pole (90° N) | 11.5 | 18.00 | 12.5 | 20.5 |
| White Horse, Canada (60° N) | 8.78 | 16.81 | 15.36 | 7.09 |
| Tokyo, Japan (35° N) | 10.73 | 13.84 | 13.32 | 10.13 |
| Addis Ababa, Ethiopia (10° N) | 11.68 | 12.46 | 12.33 | 11.53 |
| Quito, Ecuador (0°) | 12.00 | 12.00 | 12.00 | 12.00 |
| Palmas, Brazil (10° S) | 12.32 | 11.54 | 11.67 | 12.47 |
| Canberra, Australia (35° S) | 13.27 | 10.16 | 10.68 | 13.87 |
| South Pole (90° S) | 0 | 0 | 24 | 24 |

So, Table 3.3 now includes the daylength information for both the North Pole and the South Pole.
