Analyze the question prompt

The question asks to select the text in the passage that shows Jack and Bob are experienced inventors.

Evaluate the passage options

• Option (1) shows doubt and questioning about whether the device will work.
• Option (2) discusses theory versus practice and competition, but does not prove prior experience.
• Option (3) is about being ready to test the device.
• Option (4) describes their workshop/laboratory and explicitly states: "The room was fitted up as a combined workshop and laboratory, and a single glance would indicate that the two boys were by no means novices, for it contained many expensive and intricate pieces of machinery." The phrase "by no means novices" directly indicates they are experienced.

Answer:

• (1) "Say, Jack, do you have any idea that this thing is going to work?"
• (2) "I don't know, Bob, the theory is all right, but how it will work out in practice is a cat of another color; one thing is sure, though, and that is if it don't work we are out of the running in the race, for the new boat the Jenkins boys have just bought, will run circles round the Sprite."
