This document provides instructions for a quiz on LISP data structures that will be completed in teams of 1 to 3 students. It describes 7 problems to solve involving LISP functions for finding minimum/average values in lists, generating Fibonacci sequences, finding even/zero elements in lists, retrieving elements by position, and checking for membership in lists. Students are instructed to include comments, definitions, and examples for each function they provide. The document also provides contact information for the professor, Javier Gonzalez-Sanchez, and a disclaimer regarding use of the slides.

Solve 5 of the following problems
1. A function test-min that returns the lower value in a List of numbers
(test-min L)
2. A function test-average that returns the average of all values in a List of numbers
(test-average L)
3. A function test-fibonacci that prints the first n elements of the fibonacci series
(test-fibonacci n)
4. A recursive function that returns the leftmost even element in a list of numbers
(test-even L)
5. A functions that traverse a list and returns how many of its elements are 0
(test-count-zeros L)
6. A recursive function that return the N member of a list L (assuming that the
elements are numbered from zero onwards):
(test-get n L)
7. A recursive function that returns non-NIL if x is a member of the list L.
(test-is-in-list x L)
