# Brief Explanations:
A plane can contain a line if the line lies within the plane. From the diagram, line $ l $ is in plane $ \mathcal{N} $, so the appropriate phrase is "contains".
# Answer:
contains

### 21)
# Brief Explanations:
A point that is on a line means it lies on that line. Point $ P $ is on line $ l $, so the phrase "lies on" is suitable.
# Answer:
lies on

### 22)
# Brief Explanations:
A line segment (here $ \overrightarrow{PQ} $) that is in a plane means it lies within the plane. So $ \overrightarrow{PQ} $ lies in plane $ \mathcal{N} $, hence "lies in".
# Answer:
lies in

### 23)
# Brief Explanations:
Two lines that are in the same plane are called coplanar. Line $ l $ and line $ m $ are in plane $ \mathcal{N} $, so they are coplanar.
# Answer:
coplanar

### 24)
# Brief Explanations:
A line that goes through two points passes through them. Line $ l $ goes through points $ P $ and $ Q $, so "passes through".
# Answer:
passes through

### 25)
# Brief Explanations:
Two lines that meet at a point intersect at that point. Line $ m $ and line $ l $ meet at point $ P $, so they intersect at $ P $.
# Answer:
intersect

### 26)
# Brief Explanations:
Points that lie on the same line are collinear. Points $ P $ and $ Q $ lie on line $ l $ (or the line containing them), so they are collinear.
# Answer:
collinear
