[ 1/1Inequality]
    Assignment:Find the solution set of inequality -3 ≤m-1 <-2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -3 ≤ m - 1         (1)
         m - 1 < -2         (2)

---

    From inequality(1)：
         m ≥ -2
    From inequality(2)：
         m < -1

---

    From inequalities (1) and (2)
         -2 ≤ m < -1    (3)

---

    The final solution set is :
         -2 ≤ m < -1
