問題文

Two more lines close the center's file. The first line names which of two web troubles is the one that waits for a slip of a finger, since the other trouble sends a person who has keyed the address perfectly to the wrong place all the same. The other line names which of two guards the center is able to put in place this week without buying anything and without adding a fresh step to anybody's telephone call. Which pairing fills the two lines?

選択肢

  1. The trouble that one slip of a finger invites is the hidden detour, and the guard that needs no new tool is the ringing back.
  2. The trouble that one slip of a finger invites is the typo double, and the guard that needs no new tool is the wary stance.
