Answer: Cause and effect
The author is making a claim of cause and effect, because he is describing a phenomenon while outlining the consequences that will follow from it. The "cause" in the excerpt is the introduction of mandatory voting. The consequences that will follow are: 1) some uninformed people will cast ballots, but more importantly, 2) mandatory voting will motivate those voters who haven't become involved before to educate themselves, now that they need to vote.
