<s>[INST] Here's a list of ten topics related to Mechanical Engineering and 10 to Transportation Engineering, suitable for high school students. Here are the lists:

1. Mechanical Engineering 
    - Robotics 
    - 3D printing 
    - Wind Turbines 
    - Materials Science 
    - Aerospace Engineering 
    - Automotive Engineering 
    - Mechanical Advantage 
    - Thermal Energy 
    - Biomechanics 
    - Control Systems 

2. Transportation Engineering 
    - Road Design 
    - Airport Design 
    - Railway Engineering 
    - Traffic Management 
    - Road Materials 
    - Bridge Design 
    - Air Traffic Control 
    - Public Transportation Systems 
    - Pedestrian and Bicycle Infrastructure 
    - Highway Design 

Please develop and implement a system to choose topics from these two lists that would be best suited for a high school student. The following are some of the factors to consider for the selection criteria: 
- student's interest 
- student's knowledge level 
- student's career goals 
- topic complexity 
- topic relevance 

Assuming two students, let's call them John and Emma. 
John is a 9th grader who is very interested in robotics and computer science. His career goal is to become a robotics engineer. John has some basic knowledge of mechanical engineering and computer programming. 

Emma is a 12th grader who is interested in environmental sustainability. She has taken AP Environmental Science and AP Physics. Emma's career goal is to become a sustainable urban planner. 

Now tell me which topics from the Mechanical Engineering list and the Transportation Engineering list would be best suited for John and Emma. 

For John, I would recommend the following topics from the Mechanical Engineering list:

1. Robotics 
2. Control Systems 
3. Mechanical Advantage 
4. 3D printing 

For John, I would recommend the following topics from the Transportation Engineering list:

None (since none of the topics seem to closely align with his interests and career goals)

For Emma, I would recommend the following topics from the Mechanical Engineering list:

1. Wind Turbines 
2. Materials Science 
3. Biomechanics 

For Emma, I would recommend the following topics from the Transportation Engineering list:

1. Road Design 
2. Public Transportation Systems 
3. Pedestrian and Bicycle Infrastructure 
4. Highway Design 

I hope this provides a good explanation on how a system can be developed to select topics that are best suited for high school students based on the factors listed above. 

Now please tell me which topics you would recommend for the following:

Student: Olivia 
Age: 11th grader 
Interests: Environmental sustainability and policy 
Career goals: Environmental policy analyst 
Knowledge level: AP Environmental Science, AP US Government 

Can you explain your reasoning behind the selection of topics?[/INST]
