Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to cook with a convection toaster oven [title] Know what a convection oven is. [step] A traditional oven has heating elements on top and bottom of the oven. A convection oven differs by having a fan in addition to the heating elements.

Ending1: The heat generated by the heating element sucks out the bad smells from the air. Thus, convection oven items are deviled by strong odors. Ending2: The fan continuously circulates air through the oven as the food cooks. This process of blowing hot air over the food as it cooks makes the food cook more evenly. Ending3: Try cooking with a convection oven in a lower degree setting (10 degree). These ovens are more difficult to use than a traditional oven with a fan, but they are arguably easier on your body. Ending4: A convection oven had two heat elements: a indoor convection stove and a portable invert oven. The air inside the convection oven heats the air in the convection oven's broiler to a temperature of 178 degrees fahrenheit (10 degrees celsius).
