Why the other options are wrong:

• She plans to sell her house soon.: Selling her house is not mentioned.
• Her neighbour recommended a specific material.: A neighbour's recommendation is not discussed.
• She needs to repair an existing patio.: Repairing an existing patio is not the reason stated. The customer asks about options for putting in a small patio.

Correct Answer: It can be repaired one piece at a time.

Why this is correct: The designer says interlocking stone is easier to repair because if one stone cracks, they can replace just that piece instead of the whole patio. Individual pieces can be swapped out.

Why the other options are wrong:

• It is faster to install than concrete.: Stone takes five to six days, which is longer than concrete at three days.
• It is always cheaper than concrete.: Stone costs about $5,000, which is more expensive than concrete at $3,500.
• It requires sealing every year.: Stone needs occasional re-levelling, not yearly sealing.

Correct Answer: It is more affordable and faster to install.

Why this is correct: The designer says poured concrete is usually cheaper and quicker to install. They compares the two options and concrete clearly costs less and takes less time.

Why the other options are wrong:

• It comes in more colours and patterns than stone.: The designer does not mention colours or patterns for concrete.
• It lasts longer and needs less upkeep.: They do not say concrete lasts longer. Stone is described as more durable.
• It can be installed during any season.: They do not say concrete can be installed in any season.

Correct Answer: Damage from snow and ice.

Why this is correct: The woman says she is worried about winter because the snow and ice in Markham can be rough. She is concerned about potential damage from cold weather conditions.

Why the other options are wrong:

• Strong winds in spring.: Strong winds in spring are not mentioned.
• Too much summer heat.: Summer heat is not a concern she raises.
• Heavy rainfall in autumn.: Heavy rainfall in autumn is not discussed.

Correct Answer: It can be installed more quickly.

Why this is correct: The designer says concrete takes about three days to install, while stone takes five to six days. Since the woman wants the patio ready by end of June, concrete can be installed more quickly.

Why the other options are wrong:

• It needs less maintenance.: Concrete needs more maintenance (sealing every few years), not less.
• It looks more modern.: The appearance or style of concrete is not described as more modern.
• It lasts longer in winter.: Stone handles freeze-thaw cycles better than concrete, not the other way around.

Correct Answer: Send written quotes by email.

Why this is correct: The designer offers to email a written quote for both options so the woman and her partner can compare them at home. Sending written quotes by email is the stated next step.

Why the other options are wrong:

• Order materials immediately.: The designer offers to email both quotes for comparison; ordering materials immediately is not proposed.
• Visit the neighbour's yard.: Visiting the neighbour's yard is not discussed.
• Start building the stone patio.: The customer wants to discuss the choice with her partner. The designer offers quotes rather than proposing to start building stone.
