Context: the course covers hedonic pricing, the sales comparison approach, the cost approach and the income approach to real estate valuation. Students have access to a database of 500,000 Quebec transactions from 2021 to 2026 with attributes such as living area, lot size, year built, number of bedrooms and bathrooms, municipality and sale date. The professor wants a tutorial exercise. Task: write detailed instructions for a two-hour lab in which students estimate a hedonic regression, interpret its coefficients, and use it to value three sample properties, including common pitfalls and how to check residuals."72 - "Context: a small laboratory operates a cluster of twenty-nine Apple Silicon computers connected by gigabit Ethernet, with between 8 and 96 GB of unified memory each, used for scientific computing, web services and language-model inference. The laboratory wants a maintenance policy. Task: write a comprehensive maintenance checklist covering daily, weekly and monthly tasks, monitoring of temperature and disk usage, backup verification, software updates, security hygiene, and an incident response procedure for a power outage, with justification for each item."73 - "Context: a municipality in Quebec is revising its property assessment roll. Current assessments date from three years ago; prices have risen unevenly across neighbourhoods; some property types (condominiums, plexes, single-family homes) show different trends; the municipality must explain changes to citizens. Task: write a structured briefing note of at least eight paragraphs for the city council describing the methodology options, their fairness implications, communication strategy, and a timeline."74 heldout:75 - "Context: a graduate student is designing a benchmark to compare inference runtimes for mixture-of-experts language models on consumer hardware. The runtimes differ in quantization, in how they store experts (in memory or on disk), and in whether they can use several machines. The student has access to three machines with different amounts of memory and a gigabit network. Task: write a detailed experimental protocol with workloads, metrics, controls, repetition strategy, statistical analysis and reporting guidelines, explaining the rationale behind each choice."76 drift:77 fit:78 - "First, write a Python function that reverses a linked list.\n\n```python\n"79 - "Explain the rules of ice hockey in two paragraphs, then write a SQL query counting goals per player from a table goals(player, minute)."80 - "Résume en français l'intrigue d'un roman policier imaginaire, puis donne la solution de l'équation 3x + 7 = 22 étape par étape."81 heldout:82 - "Describe a sunset over the Ottawa River in one paragraph, then implement quicksort in Python.\n\n```python\n"83 - "Q: What is 17 times 23?
