However, this time they have access to the variables set by the child nodes and the data extracted from them.
Can I replace "have access" with "access". I myself think "have access" means that they can use or they can reach something if they want. They are allowed to use them, however maybe they don't use them. But, "access" means an action of finding or using something, then maybe I just can say "They can access" but not "They access".
How much my understanding of that is correct?
