When product-related safety problems occur, consumers have a responsibility to
a. discard the product
b. report the problem to the seller and the manufacturer
c. sue the seller
d. demand a full refund

I think that they key word here is "responsibility" - it's not about what the consumers want , but about what is responsible, that is: what will also be beneficial for others and for the society in general.

The responsible option here would be to b. report the problem to the seller and the manufacturer- this way other people can be warned and not endangered. 

To solve their problems, mesopotamians used irrigation, a way of supplying water to an area of land. to irrigate their land, they dug out large storafe basins to hold water supplies these ditches brought water to the feilds. to protect their feilds from flooding, farmers built up the banks of the tigris and euphrates.hope ths !
