True/False 1. Computers can generate truly random numbers. 2. The Python random function returns a pseudo-random int. 3. Top-down design is also called stepwise refinement. 4. In top-down design, the main algorithm is written in terms of functions that don't yet exist. 5. The main function is at the top of a functional structure chart. 6. A top-down design is best implemented from the top down. 7. Unit-testing is the process of trying out a component of a larger program in isolation. 8. A developer should use either top-down or spiral design, but not both. 9. Reading design books alone will make you a great designer. 10. A simplified version of a program is called a simulation
