Waiting for his best friend Mike.

Others would say his bike is cool.
1. a a b b
2. a b a b
3. a b c d
4. a a b a
Is the answer 1?

Yes.

To determine the rhyme scheme of a poem, you need to analyze the pattern of end rhymes in the lines. In this case, let's look closely at the end words of each line:

- Line 1: bike
- Line 2: Mike
- Line 3: school
- Line 4: cool

The end words of the first and second lines (bike and Mike) have the same sound, indicating that they rhyme and correspond to the first two letters in the rhyme scheme. Similarly, the end words of the third and fourth lines (school and cool) also rhyme and correspond to the last two letters in the rhyme scheme.

Therefore, based on this analysis, the correct answer for the rhyme scheme of this poem is option 2: "a b a b."
