Prolog

Given the following list of cities and features

[london_buckingham_palace, paris_eiffel_tower, york_minster, pisa_leaning_tower, athens_parthenon] 

In Prolog Write a program called member, that would be able to see if something was a member of a list. The program would inform me that sydney_opera_house was not on list by failing, yet confirm all the above were on the list by succeeding (answering yes).
