1. CANADA-U.S. TRADE CONFLICT ESCALATES

Canadian Prime Minister Mark Carney sharply escalated his criticism of the United States after withdrawing Canadian negotiators from trade talks with the Trump administration. Carney said the U.S. had demanded too many concessions while offering too little in return, including changes involving Canadian cultural protections, French-language requirements, and trade policy toward other countries. Hours after negotiations collapsed, the United States imposed 50 percent tariffs on about $20 billion in Canadian exports, and Canada announced plans for retaliatory tariffs beginning in September. Carney framed the conflict as a matter of national sovereignty as well as economics, arguing that Canada should become less dependent on the U.S. market and expand trade elsewhere. At the same time, retaliation carries risks because Canadian companies rely heavily on American customers and supplies, and additional tariffs could raise prices for consumers on both sides of the border. The dispute also threatens the stability of the broader U.S.-Canada economic relationship and raises new questions about the future of the trade agreement linking Canada, the United States, and Mexico. Prepare a trade-policy briefing for a fictional Canadian cabinet meeting. Identify three possible responses Canada could take: retaliatory tariffs, restrictions or taxes on important exports such as energy or minerals, and a strategy focused on expanding trade with other countries. For each response, explain one potential advantage, one economic or diplomatic risk, and which groups in Canada could be most affected. Conclude by identifying what information policymakers would still need before choosing among those options.

2. UNRELIABLE POLLING CREATES NEW RISKS FOR CAMPAIGNS

Recent U.S. primary elections have exposed growing problems with the way political polls are produced, circulated, and interpreted. In several races, surveys suggested that certain candidates held commanding leads, only for election results to show much closer contests or even victories by supposed underdogs. Some polls have been revealed as entirely fake, while another polling organization admitted changing respondents’ answers because the original results did not match its expectations. At the same time, prediction markets increasingly turn political expectations into numerical odds, which can influence donors, news coverage, campaign strategy, and even voters. Reliable polling has also become more difficult because traditional phone surveys are expensive and newer online or text-based methods may not accurately represent the people who ultimately vote. The concern is therefore larger than whether a particular poll is “wrong”: questionable data can help create a political narrative that changes the race it claims merely to measure. Build a poll credibility checklist that a newsroom could use before reporting on a political survey. Include at least six questions covering issues such as who paid for the poll, how respondents were selected, sample size, demographic representation, question wording, methodology, and whether full results are publicly available. Then choose one of the polling problems described in the story and explain how your checklist might have exposed the problem before the numbers shaped public expectations.

3. BIG TECH’S INFLUENCE OVER AMERICAN EDUCATION

Technology companies including Google, Microsoft, Apple, Amazon, Meta, and OpenAI have become deeply involved in American schools by supplying devices, software, curriculum materials, teacher training, and funding for educational organizations. Supporters argue that these partnerships give schools access to useful technology and career-focused instruction that public systems might otherwise struggle to provide. Critics, however, warn that corporations have financial incentives to encourage schools to adopt their products and may gain influence over what students learn about technology itself. Programs such as company-sponsored coding courses or artificial intelligence training can teach valuable skills while also familiarizing students with particular brands and presenting the industry in a favorable light. The debate has become more complicated as evidence has raised questions about whether widespread classroom technology improves academic outcomes, while concerns about privacy, screen use, artificial intelligence, and corporate power have grown. Some educators are responding with “technology civics,” an approach that asks students not only how technology works but also who builds it, who profits from it, who benefits, and what social consequences it may create. Conduct a conflict-of-interest audit of a technology program used in your school or another school you can research. Identify who developed or funded the program, what educational benefit it claims to provide, what products or platforms students are encouraged to use, and what the company could gain from participating in education. Then assess what information is missing from the program’s materials, such as discussion of privacy, labor practices, environmental costs, competition, or possible harms. Present your findings as a short memo recommending safeguards schools could use when accepting corporate-funded educational resources.

4. TEEN ACTIVISTS CHALLENGE THE EXPANSION OF A.I. DATA CENTERS

Teenagers in several states are organizing against new data centers that provide the computing power needed for artificial intelligence and other digital services. Students in California, Colorado, Texas, and Virginia have spoken at local government meetings, filed public-records requests, organized clubs, and helped opposition groups investigate projects planned near their communities. Their concerns include electricity and water use, pollution, noise, tax incentives, wildlife impacts, and new power infrastructure. Data-center companies argue that some criticisms misunderstand how the facilities operate and point to efforts such as closed-loop cooling systems, noise reduction, and renewable-energy commitments. The debate contains an unusual tension for young activists because many of them use A.I. tools regularly even while questioning the physical infrastructure required to operate them. Their activism demonstrates how debates over artificial intelligence are moving beyond software and into local decisions about land use, energy, environmental policy, taxation, and democratic oversight. Analyze a proposed data center as though you were serving on a local planning commission. Create an evidence table with four categories: environmental effects, economic effects, infrastructure demands, and community benefits or costs. For each category, identify what evidence supporters and opponents would need to provide before a responsible decision could be made. Then draft five questions you would ask the developer at a public hearing, making sure at least one question addresses transparency and one addresses how the project’s long-term costs would be measured.

5. SCIENTISTS TRACK THE GULF’S MASSIVE “DEAD ZONE”

For more than four decades, scientists have monitored a low-oxygen area in the Gulf of Mexico known as a dead zone, where conditions can become dangerous or unlivable for marine species. Much of the problem begins far inland, where nitrogen and phosphorus from agricultural fertilizers wash into the Mississippi River and eventually reach the Gulf. Those nutrients encourage large algae blooms; when the algae die, bacteria break them down and consume oxygen in the surrounding water. Fish and shrimp may flee low-oxygen areas, while organisms living near the seafloor have fewer ways to escape, creating ecological damage and additional costs for the Gulf seafood industry. The size of the dead zone changes from year to year because storms and currents can temporarily mix oxygen back into the water, making long-term scientific monitoring especially important. Addressing the problem is politically and economically difficult because pollution originates across many states, agricultural practices are deeply connected to food production, and downstream communities often bear consequences created hundreds of miles away. Create a cause-and-effect chain tracing the dead zone from cause to consequence to possible solution. Begin with fertilizer use in the Mississippi River watershed and follow at least five links through runoff, algae growth, oxygen loss, ecosystem changes, and economic effects on fishing communities. Then attach three possible interventions at different points in the chain, such as changes in farming practices, wetland restoration, or modifications to waterways. For each intervention, explain who would have to act, who would pay, and why coordinating action across many states makes the problem difficult to solve.
