Kooclaka is a Full-Line Vending Business, Which uses Vending Machines to Sell Cans or Bottles

Question: Kooclaka is a full-line vending business, which uses vending machines to sell cans or bottles of soft drinks and individual packages of snacks. When the management of Kooclaka considered whether to fill vending machines in hospitals with 330ml or 500ml cans or bottles, it decided to sell only 500ml bottles, because patients do not leave their beds very often, thus they prefer a larger, reusable bottle.

Which of the following, if true, most seriously weakens the argument above?

1. All Kooclaka’s products are manufactured by the same manufacturer.
2. The revenues from selling 500ml bottles are 5% less than for 500ml cans.
3. Kooclaka’s competitors sell only 500ml bottles in hospitals.
4. More 330ml bottles than 500ml bottles can be put in a vending machine.
5. The average number of visitors is 2.3 per hospital patient.
