True or False and why? The execution time for a program

The execution time for a program P on computer system X includes the time the CPU spends executing instructions of the operating system on behalf of P. A microprocessor system with a system clock frequency of 3 GHz will always execute programs more quickly than a different microprocessor system running at only 2.5 GHz. More code is written in high-level programming languages than assembly language because an assembly language program is so closely tied to the underlying architecture of the machine that it is not possible to run an assembly language program written for processor X on a processor Y, with a different architecture. If we know the average CPI for a program and the system clock frequency, then we can calculate the user CPU time
