"explain why professional software is not just the programs that are developed for a customer"

To put it into simple terms, software is always a continuous process of coding and updating, thus, you will never code and be done. Professional software not only consists of programs that are developed for a client, but also the compilation of documentation, configuration of data, support websites, requirements, design manuals, and evolution to make these programs operational and complete. 

A professionally done software system consists of more than one program and configuration files used to set up these programs.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
