Explanation:

• 31: A comma should be inserted after "skating" to set off the name "Bob".
• 32: A comma should be inserted after "Well" as it is an introductory word.
• 33: The sentence is correct as the comma after "young" properly separates the dependent clause from the independent clause.
• 34: The comma after "however" is unnecessary. "However" should be set off by commas on both sides. So it should be "Some kids, however, start when they are two or three years old."
• 35: A comma should be inserted after "walking" to separate the items in the list.
• 36: Commas should be inserted before and after "some say" as it is an interrupting phrase.
• 37: A comma should be inserted after "skating" to set off the prepositional phrase "with the invention of indoor skating rinks".
• 38: The two sentences are correct as they are.
• 39: A comma should be inserted after "$50,000" to separate the dependent clause from the independent clause. Also, the commas in "ten, twenty, and even thirty" are correct for separating items in a list.
• 40: The sentence is correct as the comma properly separates the two independent clauses joined by "but".
