Translate the following English argument into PL, and construct either a full truth table or an indirect truth table to determine whether it is valid :

Insurance companies contribute millions of dollars to political campaigns. If insurance companies contribute millions of dollars to political campaigns, then politicians will be reluctant to push for insurance reform. There will be meaningful insurance reform unless politicians are reluctant to push for insurance reform. Therefore, insurance companies’ contributing millions of dollars to political campaigns implies that there will not be meaningful insurance reform.
