The order of the limerick is inverted. This is the correct sequence:
There was an Old Man on a hill, Who seldom, if ever, stood still; He ran up and down, In his Grandmother's gown, Which adorned that Old Man on a hill.
Answer:
The lines which have two beats and rhyme with each other are:
He ran up and down,
In his Grandmother's gown
Step-by-step explanation:
When we speak of beats in poetry, we refer to the number of stressed words or syllables inside a line. In the limerick we are analyzing here, some lines have three beats, some have two. That means some lines have three, some have two stressed words. Let's highlight those words:
There was an Old Man on a hill,
Who seldom, if ever, stood still;
He ran up and down,
In his Grandmother's gown,
Which adorned that Old Man on a hill.
We have already found our answer. The lines that have two beats are: He ran up and down, / In his Grandmother's gown. Now, let's see if they rhyme. Rhyming means the final words of each line must correspond in sound. "Down" and "gown" do have such a correspondence. Their final sound is the same.
