Why the other options are wrong:

• They do not need sunlight.: Determinate tomatoes are recommended for their compact size and earlier fruit, not because they grow without sunlight.
• They can survive frost all summer.: The employee describes earlier fruit production, without claiming that determinate tomatoes survive frost all summer.
• They are cheaper than other tomatoes.: The price distinction concerns tomato seedlings in larger pots, not determinate versus indeterminate varieties.

Correct Answer: Around May 25th.

Why this is correct: The worker says the risk of frost usually passes by May 25th in Fort McMurray. She recommends planting tomatoes outside around that date to be safe.

Why the other options are wrong:

• In early June.: Early June is when cucumbers should be planted, not tomatoes.
• In the middle of May.: The middle of May would still have frost risk.
• At the beginning of May.: The beginning of May is too early.

Correct Answer: Kale and lettuce.

Why this is correct: The worker says kale and lettuce are cold-tolerant and can handle a light frost. Many gardeners start them earlier. These are the two vegetables explicitly described as cold-tolerant.

Why the other options are wrong:

• Tomatoes and cucumbers.: Cucumbers are said to need more heat, and tomatoes are to be planted after frost risk. Kale and lettuce are the pair explicitly described as cold-tolerant.
• Cucumbers and peas.: Peas are not mentioned in the conversation.
• Tomatoes and peppers.: Peppers are not discussed.

Correct Answer: Gradually expose seedlings to outdoor conditions.

Why this is correct: The worker says the man needs to harden the seedlings off by putting them outside for a few hours a day before planting. This gradual exposure to outdoor conditions prepares them when there is no greenhouse.

Why the other options are wrong:

• Buy larger pots.: Buying larger pots is not the suggested step.
• Water the plants twice a day.: Watering twice a day is not mentioned.
• Use special fertilizer.: Hardening off is described as putting seedlings outside for a few hours each day; special fertilizer is not mentioned as the preparation.

Correct Answer: Tomatoes in larger pots.

Why this is correct: The worker says most seedlings are $3.49 each, but the tomato seedlings in larger pots are $4.99. The tomatoes are more expensive because they are more established plants.

Why the other options are wrong:

• Kale seedlings.: The employee specifies $4.99 for tomato seedlings in larger pots, without assigning that higher price to kale.
• Cucumber seedlings.: The employee specifies $4.99 for tomato seedlings in larger pots, without assigning that higher price to cucumber.
• Lettuce seedlings.: The employee specifies $4.99 for tomato seedlings in larger pots, without assigning that higher price to lettuce.

Correct Answer: Purchase seedlings and possibly soil or fertilizer.

Why this is correct: The man says he will start with kale, lettuce, and determinate tomatoes. The worker then asks if he needs soil or fertilizer too. He will likely buy those seedlings and possibly extra supplies.

Why the other options are wrong:

• Return home to build a greenhouse.: He is not going home to build a greenhouse.
• Wait until July to start his garden.: He is buying now, not waiting until July.
• Buy only cucumber seedlings.: He chose kale, lettuce, and tomatoes, not just cucumbers.
