The federal government set up a tax credit to help Canadians retrofit their homes to make them more energy efficient. For example, Canadian residents received funding to re-insulate their houses. 18. Increasing the insulation value of a house will reduce qquad energy lost while qquad household heating costs. The statement above is best completed by the answers in row: Row & i & i i square & thermal & decreasing square & electrical & increasing square & electrical & decreasing square & thermal & increasing

## Step 1: Understand the context of the question<br />### The question is about increasing the insulation value of a house to make it more energy efficient. This typically involves reducing the amount of thermal energy lost, which in turn decreases household heating costs.<br /><br />## Step 2: Identify the correct type of energy and change<br />### Increasing insulation primarily affects thermal energy because it reduces heat loss. Therefore, we are looking for an option where \( i \) is "thermal."<br />### Additionally, since better insulation reduces energy loss, the change should be "decreasing." Therefore, we are looking for an option where \( ii \) is "decreasing."<br /><br />## Step 3: Match the correct row from the table<br />### From the provided rows:<br />- Row 1: thermal, decreasing<br />- Row 2: electrical, increasing<br />- Row 3: electrical, decreasing<br />- Row 4: thermal, increasing<br /><br />### The correct match is Row 1, which has "thermal" for \( i \) and "decreasing" for \( ii \).
