1) Answer: Spring is rainy and wet
Explanation: The expression "the world" here refers not to the actual entire planet, but to the limited "world" that children experience when they go outside to play after a spring rain. Puddles are a part of what makes the season wonderful for playing outside.
2) Answer: Spring has only recently arrived
Step-by-step explanation: The title, which ends abruptly with a hyphen, is actually joined with that hyphen to the first line. Just-spring is one of the made-up words in this poem and it points to the fact that spring has just started. We can tell all other options are incorrect because they don't reflect the appreciation for spring that we see throughout the poem.
3) Answer: Repetition
Step-by-step explanation: The phrase "the (...) balloonman whistles far and wee" appears three times in the poem, each time with a different distribution of words and increasing space between the last three words, giving the action a certain sense of distant and sluggish repetition.
