Which climate description matches the notes about Canada?

• A. Mild summers, dry winters
• B. Very warm summers, rain year-round
• C. Very warm summers, rain comes during summer, cold winters frost breaks up soil, and kills pests
• D. Very dry summers with frequent drought

Answer: (C)

The main idea is that Canada’s agricultural climate combines warm summers with rainfall during the growing season and cold winters that bring frost. This frost is useful because it loosens the soil through freeze–thaw action and also helps control pests that overwinter. So a description that says very warm summers with rain in summer and cold winters with frost that breaks up soil and kills pests fits these seasonal effects. It reflects how moisture supports crops in the growing season while frost and cold winters influence soil structure and pest dynamics. The other options imply dry winters, drought, or rain year-round, which don’t align with the typical Canadian pattern described.
