In a more complex plot diagram, you will often see these categories going up and down the stairs to the climax in order:
Exposition/Beginning, Rising Action, Climax/Middle, Falling Action, and then the Resolution/End.
This helps to remember because the rising action (building of the conflict) would be categorized and placed before the climax. The climax should also be known as when the conflict is finally brought to the surface. A character should spend their entire falling action trying to find a way to resolve it. Because of this, your answer is going to be 'in the beginning.' This is when you are going to see the conflict start to build as it struggles to reach the middle or the climax. Remember that the climax is most likely where you are going to hit the breaking point and major importance of the conflict. You are rising (action) and building up towards it.
Explanation: The paraghraph says nothing about it being cold or less sunny. It tells us that last summer there was a lot of rain but that this summer not as much rain meaning that the lawns didn't grow as much or as fast.
