Welcome to The Globe and Mail’s business and investing news quiz. Join us each week to test your knowledge of the stories making headlines. Our business reporters come up with the questions, and you can show us what you know.

Take our quiz and find out what happened in business.

1What did Prime Minister Mark Carney term “outrageous” this week?

a. The price of milk

b. The conduct of a U.S. trade negotiator

c. The sale of an auto plant

d. The situation in the Strait of Hormuz

c. Mr. Carney lambasted auto maker Stellantis, calling its move to sell its car plant in Brampton, Ont., to defence contractor Roshel “completely outrageous.” The Prime Minister vowed to protect workers and ensure that previous government subsidies to Stellantis are returned. “Stellantis is failing to respect their commitment to the workers of this plant and also to the Canadian government and Canadians,” Mr. Carney told reporters in Montreal.

2The stock price of chip maker Nvidia hit the skids this week following reports that chief executive Jensen Huang had an affair with a woman alleged to be a Chinese spy.

a. Fifth columnists

b. Honeytraps

c. Moles

d. Good spies

b. Such agents are commonly known as honeytraps. In the case of Nvidia, China has denied that it used a honeytrap to spy on Mr. Huang, calling such claims “groundless speculation and slander.” Rather than being a perpetrator of such deceptions, Beijing claims it is typically the victim. The Ministry of State Security, China’s top intelligence agency, regularly warns of honeytrap operations run by foreign countries for the purpose of collecting sensitive information from Chinese citizens.

a. London

b. Shanghai

c. Toronto

d. Peter Munk, the founder of Barrick, was a vocal Canadian patriot. His successors appear to be following a different path. The company announced this week that it will be listing the shares for its new unit, to be called American Barrick Gold Corp., in New York. The miner said earlier in the year it intended to seek a secondary stock listing for American Barrick in Toronto, but that no longer appears to be part of the plan.

d. Its environmental-investing division

c. You think you have problems picking winning stocks? So does CPPIB. It is laying off dozens of employees from its active equities division, which invests in public companies and those that are soon to be listed publicly.

Investors who managed to snag shares in the company’s highly anticipated IPO are doing considerably better, but are still far from making a fortune. They are sitting on gains of about 3.5 per cent.
