Which two decisions made by Taft angered his progressive supporters?

Progressives were angered when Taft signed the Payne-Aldrich Tariff Act instead of vetoing it, because they believed it kept tariffs too high. They were also upset by his appointment of Richard Ballinger, whom conservationists viewed as hostile to conservation, as Secretary of the Interior. Taft did pursue antitrust enforcement, so choice B does not fit.
