Which one of the following is most strongly supported by the information above?
(A) If Johnson is a commercial raspberry grower and Wally’s Plants is not a large nursery, then the shipment of raspberry plants that Johnson received was probably guaranteed to be
disease-free.
(B) Johnson is probably not a commercial raspberry grower if the shipment of raspberry plants that Johnson received from Wally’s Plants was not entirely as it was guaranteed to be.
(C) If Johnson is not a commercial raspberry grower, then Wally’s Plants is probably not a large nursery.
(D) Wally’s Plants is probably not a large, well-run nursery if it sells its raspberry plants primarily to commercial raspberry growers.
(E) If Wally’s Plants is a large nursery, then the raspberry plants that Johnson received in the shipment were probably not entirely as they were guaranteed to be.
Tricky question. Here is the explanation:
Most large nurseries sell raspberry plants with two conditions:
- primarily to commercial raspberry growers
- only plants that are guaranteed to be disease-free
However, Wally's plants sent Johnson diseased raspberry plants.
So what does this imply:
- Perhaps Wally's plants is not a large nursery (since most large nurseries guarantee disease free plants)
- If Wally's plants is a large nursery, Johnson may be a commercial raspberry grower (since large nurseries supply primarily to commercial growers)
- If Wally's plant is a large nursery, Johnson probably did not receive what he was guaranteed (since most large nurseries guarantee disease free plants)
etc
(A) If Johnson is a commercial raspberry grower and Wally’s Plants is not a large nursery, then the shipment of raspberry plants that Johnson received was probably guaranteed to be disease-free.
- If Wally's Plants is not a large nursery, ... - everything after this is pointless to our discussion.
We only know about what to expect is Wally's plants is a large nursery. We don't know how "not large nurseries" behave. So irrelevant.
(B) Johnson is probably not a commercial raspberry grower if the shipment of raspberry plants that Johnson received from Wally’s Plants was not entirely as it was guaranteed to be.
- It doesn't matter whether Johnson is a commercial raspberry grower or not. Most large nurseries sell disease free plants only.
We are not given that they sell disease free plants to commercial growers. They sell disease free plants, full stop.
(C) If Johnson is not a commercial raspberry grower, then Wally’s Plants is probably not a large nursery.
If Johnson is not a commercial grower ... - we don't know anything about how non-commercial growers work. So I will let it be for the time being since the argument doesn't tell me anything about them.
(D) Wally’s Plants is probably not a large, well-run nursery if it sells its raspberry plants primarily to commercial raspberry growers.
Not correct. If it sells primarily to commercial buyers, I cannot say whether Wally's Plants is a large nursery or not. I don't know anything about how small nurseries sell. I anyway know that large nurseries sell primarily to commercial buyers. Hence there is no way I can imply that if it sells to commercial buyers, it is NOT a large nursery.
(E) If Wally’s Plants is a large nursery, then the raspberry plants that Johnson received in the shipment were probably not entirely as they were guaranteed to be.
Most large nurseries guarantee disease free plants. If Wally's is large, it
probably guaranteed disease free plants. So Johnson
probably did not receive the plants as per guarantee. This is correct.
Hence answer (E)
How do we come to know that even if Wally’s Plants is a large nursery ,it comes under category of those large nurseries which guarantees xyz ?
