Why the other options are wrong:

• She is unhappy with her current energy provider.: She never mentions being unhappy with her energy provider.
• She wants to renovate her entire basement.: She does not talk about renovating the entire basement.
• Her furnace recently stopped working completely.: She says the furnace is about twenty years old and asks about replacement before winter. A complete breakdown is not mentioned.

Correct Answer: It adjusts heat output more gradually.

Why this is correct: The technician explains that a modulating furnace adjusts gradually, keeping the temperature more even. This gradual adjustment is the main difference he describes. A two-stage furnace only switches between low and high.

Why the other options are wrong:

• It requires less annual maintenance.: Both furnaces need yearly servicing; the modulating furnace's gradual adjustment is the stated difference.
• It uses a different type of fuel.: The technician describes how the furnaces adjust their output. Different fuel types are not mentioned.
• It is designed only for very large homes.: He never says modulating furnaces are only for large homes.

Correct Answer: They require the furnace to meet a minimum efficiency level.

Why this is correct: The technician says SaskEnergy offers a rebate of up to $650 if you install a furnace that is at least 95 percent efficient. The rebate is tied to meeting a minimum efficiency level. Both types could qualify.

Why the other options are wrong:

• They apply only to modulating models.: He does not say the rebate applies only to modulating models.
• They are offered by the city of Regina.: The rebate comes from SaskEnergy, not the city of Regina.
• They cover the full cost of installation labour.: The rebate is up to $650 for a qualifying furnace. No installation-labour amount is given to establish that the rebate covers it completely.

Correct Answer: It would need extra installation work due to ceiling height.

Why this is correct: The technician says the basement ceiling height is a bit low, so a modulating furnace would require extra venting work. A two-stage model would fit with minimal changes. The physical space in her house is the problem.

Why the other options are wrong:

• It cannot handle Regina's cold winters.: The technician identifies extra venting work for a modulating furnace because of the low basement ceiling, not an inability to handle Regina winters.
• It has a much shorter lifespan.: Both types last 15 to 20 years with yearly service.
• It would not qualify for the SaskEnergy rebate.: Both types can be at least 95 percent efficient, so both could qualify for the rebate.

Correct Answer: She is trying to balance comfort with overall cost.

Why this is correct: The woman mentions liking quieter operation but also watching her budget. She asks about costs, rebates, and installation issues. This shows she wants comfort but needs to keep spending reasonable.

Why the other options are wrong:

• She plans to sell her house soon.: There is no mention of selling her house.
• She prefers to avoid regular maintenance.: She does not say she wants to avoid maintenance.
• She wants the most advanced technology available.: She does not ask for the most advanced technology - she is comparing options carefully.

Correct Answer: The technician will send a written estimate for review.

Why this is correct: The technician offers to send a written quote this week. Installation would follow approval within two to three weeks; receiving the quote is the proposed next step.

Why the other options are wrong:

• The woman will apply directly to SaskEnergy for approval.: She does not say she will apply to SaskEnergy directly.
• The technician will immediately start the installation.: He says installation happens after the quote is approved, not right away.
• The technician will remove the old furnace.: He does not mention removing the old furnace as the next step.
