The Quiz, Question 1
The perl scripts execute the system call with the number 4, sys_write(), supplying a file descriptor of "1", which denotes stdout, the standard address of the ELF header of the executed binary (increased by 1 to skip the leading 0x7f) and an output length of "3". The perl script outputs "ELF" on my Linux box.
