I need another hypothesis: Mom and I were baking a cake for my brother's birthday. We didn't have any baking powder. The recipe said to add one teaspoon of baking powder to the cake batter. Since that's such a small amount we baked the cake anyway. We were very disappointed when the cake came out of the oven flat instead of fluffy. We think maybe we needed to add the baking powder.
So turn your last sentence into a hypothesis.
