Store O sells the same fish but in lower prices than Store U in a neighborhood town (Uptown). Both of these stores buy the fish in same price and quality. But the profit of Store O is higher than that of Store uptown. Therefore, the amount of fish in Store O sold must be higher than that in Store U. Support.
My answer: Because people in the uptown like to buy the fish in the town of their neighborhood.
Other confused choice: The maintenance cost of Store O is lower than store U. (Actually this one weaken the argument.)
I think: Prfit=Sales-cost, and sales= price*amount, so the correct choice must be either cost of O lower than U, or amount sold by O is greater than U, right?

the confusing alternative just provides another reason
in other words , weaken the argument in the problem
