Answer: Lines 1 and 3 and lines 2 and 4
Explanation: Look at the last word on the end of each line.
Say these words aloud. "Thought" and "caught"; "turn" and "fern".
They sound almost the same, don't they?
When you're looking for words to rhyme, often they need to sound the same.
Also, sometimes you can tell if words rhyme if just one or two letters in front of the word are different, like "star" and "car".
