Answer:
(4) Someone yelled, "It tells me that if I drink soft drinks I'll never have worms!"
Step-by-step explanation:
The teacher is giving a demonstration explaining how water is healthier than soft drinks because when placed in water, the worm swims while when it's placed in soda, the worm dies.
A student makes an argument that's not logically connected or making much sense, saying that if they drink soft drinks they won't have worms. This sentence is not connected to the rest of the passage.
hope this helped :)
