1The saddest moment this week came in Manhattan, when Brian Thompson, chief executive of UnitedHealth’s insurance unit, was shot and killed. Mr. Thompson was in the city:

2It was a wild week in South Korea, where financial markets shuddered after the country’s president briefly imposed martial law. What is the president’s name?

d. France. Prime Minister Michel Barnier resigned after opposition lawmakers voted to topple his government. This is the first time a French government has been defeated by a censure motion since 1962 and reflects the deep disagreement in the country over how France should address its budget shortfall.

4To be sure, no wild week is complete without more rants from Donald Trump. Who did the U.S. president-elect just threaten with 100 per cent tariffs?

b. Countries that try to undermine the U.S. dollar. Mr. Trump said he would levy the 100 per cent tariffs against the nine countries in the BRIC alliance – Brazil, Russia, India, China, South Africa, Egypt, Ethiopia, Iran and the United Arab Emirates – if they tried to introduce a BRIC currency that would allow them to avoid using the U.S. dollar for international transactions.

5Closer to home, Ontario’s auditor-general issued a devastating report this week on Premier Doug Ford’s plan to redevelop the Ontario Place site on Toronto’s waterfront. What does the report say?

d. All of the above. The report from Auditor-General Shelley Spence says the process used to award a 95-year lease to an Austrian company was not “fair, transparent or accountable to all participants” and broke the province’s own rules.

However, a small personal item, such as a purse or laptop bag will still be allowed on board for free, as will strollers, mobility aids and medical devices. Starting Jan. 21, lower-tier customers will also have to pay if they want to change the seat assigned to them at check-in.

9Crypto is on a run, too. This week, for the first time, bitcoin surpassed:

12Which book has enjoyed a 22-per-cent jump in sales in the United States this year?

b. The Bible. The good book has enjoyed a surprising burst of sales this year. Why? No one is quite sure. Perhaps it’s a search for reassurance in an age of anxiety. Or perhaps it’s improved marketing. Publishers are offering a dizzying array of Bibles, including graphic-novel versions and editions aimed specifically at men or young readers.
