Answer: "A school district can bring in hundreds of thousands of dollars in revenue from the ads over the course of several years." & "Ads would need to be limited to those that target adults outside of the school buses and not the children inside."
Step-by-step explanation:
The sentence "In fact, putting limitations on anything helps make things more beneficial for people." sounds short with no proof or evidence.
"Student(s) may have thought this made a good point that helps support the argument that ads should be allowed on school buses." They may have given some evidence, but it's not the strongest.
"An advertising program can greatly benefit a school district as long as there are limitations put on the ads." This is basically just rewording the claim.
The other two sentences are correct because it shows strong proof of the reasons in a understanding way.
