生成这个题目的讲解---**Question 1**
* **Question Number:** 1.
* **Points:** 5分 (5 points)
* **Question Stem:**
若集合 M={x|√x < 4}, N={x|3x≥1}, 则 M∩N= (C )
*Mathematical breakdown of M:*
For `√x` to be defined, `x ≥ 0`.
Given `√x < 4`, squaring both sides (since both sides are non-negative) yields `x < 16`.
Combining these, `M = {x | 0 ≤ x < 16}`.
*Mathematical breakdown of N:*
Given `3x ≥ 1`, dividing by 3 yields `x ≥ 1/3`.
So, `N = {x | x ≥ 1/3}`.
*Mathematical breakdown of M∩N:*
The intersection of M and N means finding `x` that satisfies both conditions: `(0 ≤ x < 16)` AND `(x ≥ 1/3)`.
This results in `1/3 ≤ x < 16`.
Therefore, `M∩N = {x | 1/3 ≤ x < 16}`.
* **Options:**
* A. {x|0≤x<2}
* B. {x|1/3≤x<2}
* C. {x|3≤x<16}
* D. {x|1/3≤x<16}
