A developer has promised that either he or the owner will install a sewage system in a recently built house.


If the developer works to install the sewage system, it can be inferred that the owner does not help only if it is also true that

a.the developer keeps his promises

b.the developer often breaks his promises

c.the owner does not want the sewage system

d.the developer and the owner try to avoid working together to install the sewage system

e.the developer’s promise precludes him and the owner from both helping to install the sewage system

Can someone pls explain what the question means in the first place?

dazzle,

The question asks you to pick a choice that ensures that if the developer works to install the system, the owner does not work on installing the system.

Hence, you are looking for a choice that states that either the developer or the owner would work on installing the system and that both cannot work together to install the system. Choice E is worded appropriately to ensure that. Note that while choice D may seem close, it does not preclude the developer and owner to work together.

I hope this helps.
