問題文
Two groups sit at the same level of an inventory and both of them give a value for the same variable. A team wants the value from the group they name to win, and writes the variable that raises a group's rank into the variable file of that group. Nothing changes. Which statement is correct?
選択肢
- It has an effect only when both of the groups carry it, because a group that is left without it is always merged last of all.
- It has an effect in an inventory source alone, because it is read at the point where the directory of group variable files is loaded.
- It has an effect in the variable file of any host of that group, because a value that is set on a host outranks the value of every group.
- It has an effect only while a play names both groups in its pattern, so the rank has to be handed over on the command line instead.
