The Wall Street Journal's daily business news quiz tests readers on nine key developments affecting markets and the economy. Questions cover everything from regulatory actions to demographic health trends, giving subscribers a quick pulse check on important developments.

Jeanine Pirro's U.S. Attorney's Office issued subpoenas to major banks, probing practices that could signal increased regulatory scrutiny. Meanwhile, a Washington building fetched $80 million in a federal sale, and May inflation climbed to a three-year peak of 4.2%, with one component driving over 60% of the increase.

The quiz also examines political shifts, including a Democratic Senate primary upset and a surprising vote against executive pay taxes in a progressive city. Healthcare guidelines for a newly defined syndrome affecting millions of Americans round out the business-relevant questions.

This quiz format helps busy executives stay current on multiple fronts simultaneously, from legal risks facing financial institutions to macroeconomic trends that influence investment decisions. The mix reflects how interconnected modern business news has become.
