The correct order of the sentences to show a smooth linear progression of events is:
"Taylor, age 10, plants an apple seed. A tiny apple tree sprouts from the ground. Apples grow on the tree. Taylor, now a teenager, picks an apple off the tree."
This order shows the planting of the seed, the growth of the tree, the production of apples, and finally, Taylor picking an apple, which reflects a logical timeline of events.
