Now for the segment of pseudo-code above, assume that the language being used here has dynamic scope as discussed in class and in the textbook. Provide a) the output of this program and b) in 2-5 short sentences defend your answer. Note that if you think the program will terminate with an error due to its scope rules, give that as your answer to part a) and then explain where the error occurs and why in part b).
