The xv6 pstree project requires to add a new system call getprocs. In order to add the new system call getprocs, what C code changes need to be made to the following code fragment in xv6 syscall.c? extern int sys_chdir(void);extern int sys_close(void);…extern int sys_wait(void);extern int sys_write(void);extern int sys_uptime(void);static int (*syscalls[])(void) = {[SYS_fork]    sys_fork,[SYS_exit]    sys_exit,…[SYS_mknod]   sys_mknod,[SYS_unlink]  sys_unlink,[SYS_link]    sys_link,[SYS_mkdir]   sys_mkdir,[SYS_close]   sys_clos,};voidsyscall(void){ int num; num = proc->tf->eax; if(num > 0 && num < NELEM(syscalls) && syscalls[num]) {   proc->tf->eax = syscalls[num](); } else {   cprintf(“%d %s: unknown sys call %d\n”,           proc->pid, proc->name, num);   proc->tf->eax = -1; }}  

Hypothetical: A recent poll tried to get a sense of voter turnout in the upcoming election.  They ask “Are you or are you not interested in politics and did you vote in the last presidential election?”  Based on this one question, the response was either a “Yes” or “No.”  Based on this question, researchers concluded that even those not interested in politics will vote in the next election.      Just based on this information, discuss and define the problem with this as a scientific/reliable poll (assume the number of people asked was an appropriate size).  Focus on just one problem with the poll.  Use and define all appropriate terms as discussed in this course.  (Identify the error, define the error, apply it to the facts of the scenario).   rubric proficient competent novice identify ONE relevant error     4 pts    2 pts    0 pts define the error    8 pts    4 pts    0 pts apply it to the facts of the scenario     6     3     0
