Passage: My classmates and I needed to plant a nice tree in front of the new school building that was just built this year . I wanted to find a tree that would last a quite long time . We found a nice pine tree that was just large enough to be a foot . We dug a nice hole in the ground , and insured the soil was the proper type to accept a tree of this size . It had to be nice and soft , and in a safe location where kids wo n't trample over it . We planted the tree and began to fill in the surrounding area of it with soil to make sure it would hold in place as perfect as possible . The tree looked perfect and was ready to withstand the first school year outside the new building . Question: When did they insure it was wide enough for the tree? Option1: when the school was built Option2: after digging the hole
after digging the hole
