Most large nurseries sell raspberry plants primarily to commercial

Question

Most large nurseries sell raspberry plants primarily to commercial raspberry growers and sell only plants that are guaranteed to be disease-free. However, the shipment of raspberry plants that Johnson received from Wally’s Plants carried a virus that commonly afflicts raspberries.

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)

Most large nurseries sell raspberry plants primarily to commercial raspberry growers and sell only plants that are guaranteed to be disease-free. However, the shipment of raspberry plants that Johnson received from Wally’s Plants carried a virus that commonly afflicts raspberries.

Type- inference

(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.- Incorrect; if the shipper isn't a large nursery, then we have no idea whether it's 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. - Incorrect
(C) If Johnson is not a commercial raspberry grower, then Wally’s Plants is probably not a large nursery. - Incorrect; we just know that large nurseries sell "primarily" to commercial growers. That still leaves them free to also sell to non-commercial growers. So the fact that Johnson is not a commercial grower wouldn't be enough for us to say that Wally's 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. - Incorrect - "well-run" is out of scope
(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.- Correct

We know that  most  large nurseries sell  only plants that are guaranteed  to be disease-free. But Wally received a shipment of diseased plants. If he bought it from a large nursery, it was probably guaranteed to be disease-free. But since the shipment is actually diseased, it couldn't be entirely in keeping with that guarantee.

Answer E

rahul6019 · Answer

For inference questions it is best to stick to the given content. Premise says that if a nursery is large, then it guarantees disease free plants to commercial growers. Period. Nothing else is given about any other nurseries and hence any conclusion on them would be invalid.

From answer choices, only E satisfies this point.

From answer choices, only E satisfies this point.

Mavisdu1017 · Answer

I think the first sentence of stimulus tells us 2 premises:
(1) Most large nurseries sell raspberry plants primarily to commercial growers
(2) The plants are disease-free as long as they are sold to commercial growers

According to the premises above, I think I can deduce---> if a recipient doesn't get disease-free plants, then the recipient might not be a commercial growers. So I don't know where Option B is wrong? Hope expert helps. Thanks

There are a lot of tricky details in the language of this passage!

Notice that the passage only talks about " large  nurseries." Most of  these  nurseries:

1) sell raspberry plants primarily to commercial raspberry growers, and 
2) sell only plants that are guaranteed to be disease-free.  
We don't know anything whatsoever about  non-large  nurseries -- maybe these other nurseries sell to non-commercial growers and offer different guarantees.

Now, Johnson bought some raspberries from Wally’s Plants and, unfortunately, the plants are diseased.

But what do we know about Wally's Plants? Nothing whatsoever -- it  could  be a large nursery, and therefore follow the rules listed above, or it could be a small nursery.

Here's (B):
 
The passage doesn't support (B) because we don't know what kind of nursery Wally's Plants is and what kinds of guarantees it offers. So, we have no idea whether Johnson is likely to be a commercial grower or not.

I hope that helps!

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. - WRONG. Out of scope actually.
(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. - WRONG. It may or may not be true.
(C) If Johnson is not a commercial raspberry grower, then Wally’s Plants is probably not a large nursery. - WRONG. four possibility are there based on this logic and all of them have equal likelihood.
(D) Wally’s Plants is probably not a large, well-run nursery if it sells its raspberry plants primarily to commercial raspberry growers. - WRONG. Like A, this is also irrelevant.
(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

Chose D.

This is how i understand it now.
Large nurseries(A) ----(primarily sell)----> Commercial raspberry grower(B)
In between, primarily selling is the transactional aspect which may or may not vary. So, we need not worry about the what B is or what happens to it - similarly for A also.

In E, though it looks like it is breaking the passage boundaries, it touches upon the vary aspect one may not, in general, think of to do so. What if out of 100 guaranteed plants one carries a virus?

But the first line states that "  Most   of the large nurseries..."
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 ?

beacuse MOST large nurseries are giving guarantee but not all

thanks

Question stem: Which one of the following is most strongly supported by the information above?
We need the option most strongly (best) supported by the argument, not the option that is established beyond doubt.

Also note the use of highlighted "probably"s above in my explanation of option (E). Option (E) itself claims that the "shipment was probably not as guaranteed". Everywhere there is some leeway. We are only discussing the most probable case.

Hi,  Roma123

Let us break down the entire sentence

(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.

Intial assumption that we need to keep in our mind is large nurseries do not sell contaminated packages , therefore the packages they might haave send were not for john therefore our answer 
Hope this helps
