keywords: 

{'average velocity': [0, 0, 2, 2], 'average speed': [0, 2, 4, 2], 'circular path': [0, 0, 1, 2], 'ratio': [1, 0, 1, 12], 'circumference': [0, 0, 4, 0], 'distance': [0, 3, 3, 3]}

The question asks for the ratio of average speed to average velocity for a person moving along a circular path by a distance equal to half the circumference in a given time. Let`s dissect each option to find the correct answer:

1. Option 1: 0-5

This option does not provide any information that relates to finding the ratio of average speed to average velocity, so it can be eliminated.

2. Option 2: 0-5TI

This option also does not provide any relevant information, so it can be eliminated.

3. Option 3: 0-75*

Similar to the previous options, this does not give any information related to the ratio of average speed to average velocity, so it can be eliminated as well.

4. Option 4: 1-0

This option is correct. The ratio of average speed to average velocity for a person moving along a circular path by a distance equal to half the circumference in a given time is 1-0.

In conclusion, the correct answer is option 4, which states that the ratio of average speed to average velocity is 1-0.
