Why the other options are wrong:

• They are cheaper than non-native plants.: The employee does not compare native plants to non-native ones in terms of price.
• They grow faster than regular lawn grass.: Growing speed is not discussed in the conversation.
• They are the only plants allowed by the city.: There is no city rule mentioned that limits plant choices.

Correct Answer: Blanketflower.

Why this is correct: The employee explicitly says blanketflower stays around 30 centimetres tall. Bluebunch wheatgrass is described as about 60 centimetres.

Why the other options are wrong:

• Snowberry.: Snowberry is described as a shrub with white berries, but no 30-centimetre height is given for it.
• Nootka rose.: Nootka rose is described as a shrub with pink flowers and thorns, but no 30-centimetre height is given for it.
• Bluebunch wheatgrass.: Bluebunch wheatgrass is described as about 60 centimetres tall, rather than 30.

Correct Answer: Deer usually avoid it.

Why this is correct: When the homeowner mentions that deer come through his yard, the employee says deer tend to avoid snowberry. This is a helpful trait for gardens in areas with deer. The employee also notes that deer may nibble on Nootka rose instead.

Why the other options are wrong:

• It needs watering every day.: Daily watering is not mentioned for any plant in the conversation.
• It grows taller than the fence.: The employee does not say snowberry grows taller than the fence.
• It has pink flowers in summer.: Pink flowers are a feature of Nootka rose, not snowberry.

Correct Answer: Natural rainfall in the area is usually enough.

Why this is correct: After the first summer, natural rainfall in Kelowna is usually enough. This is a usual expectation, rather than a promise that watering will never be needed.

Why the other options are wrong:

• They require a drip irrigation system to survive.: A drip irrigation system is never mentioned in the conversation.
• They need to be watered at least twice a week.: The employee says once a week during the first summer only, not twice a week long-term.
• They must be watered the same as regular lawn grass.: The employee says native plants usually need less water once established. No watering comparison with regular lawn grass is given.

Correct Answer: He wants to keep his lake view clear.

Why this is correct: The man asks about plant height because he does not want anything blocking his lake view. The employee answers with the heights of the two plants already recommended.

Why the other options are wrong:

• He needs plants that grow very quickly.: Fast growth is not something the homeowner asks about.
• He prefers plants with strong scents.: Scented plants are not discussed at all.
• He plans to sell his house soon.: Selling his house is never mentioned in the conversation.

Correct Answer: Choose a few native plants to try.

Why this is correct: At the end, the homeowner says he will start small and see how it goes. The employee agrees this is a smart approach. This suggests he will pick a few native plants to try first rather than doing a large project.

Why the other options are wrong:

• Ask the city to change watering rules.: He does not mention wanting to change city watering rules.
• Wait until next year to buy plants.: He sounds ready to start now, not wait until next year.
• Remove all the shrubs from his yard.: Removing all shrubs is not his stated plan. He says he will start small with native plants and see how it goes.
