Using the database of the House of Representatives or the Senate, trace the antecedent bills of RA9593 (Tourism Act of 2009). Make a map or diagram that shows the introduction, substitution, consolidation of bills, and finally approval of the law. Relate to previous bills in the previous Congress if possible.

An additional bill to find out is a revision of RA9593. That is to say, include bills that tackled amendments to the law as a result of the policy cycle having been concluded.
