On a sunny day, Riley is cutting branches from a tree in her yard. At midday, she takes a break, leaving a pile of branches and leaves on the ground. When she returns and gathers the branches, she notices the leaves are wilted and crisp. Which of the following describes what most likely happened to the leaves?

• The trees had not received water for a long time before being cut.

• The warm temperature caused moisture to evaporate from the leaves.

• The nutrients cannot reach the leaves if the tree's branches are not upright.

• The leaves had been covered in frost the week before but had not wilted until now.
