Final answer:
The reference provided does not match the question about license plate inspections; vehicle inspections are governed by local laws, and the timeframe can vary.
Step-by-step explanation:
It seems like there is a mix-up in the information provided regarding licensing and the need for a license plate to be inspected. The information you've provided seems to be related to a syllabus for a geography course, particularly the topics of 'Physical Patterns and Processes', 'Geography Basics', and 'Human Activity and the Environment' over a span of 15 days. However, these topics do not relate to the inspection time frame for a vehicle's license plate or licensing requirements.
Typically, license plate or vehicle inspections are regulated by state or national laws, and the timeframe can vary from one jurisdiction to another. For accurate information, please consult your local department of motor vehicles or equivalent authority.
