Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives. However, since there are several winemakers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these winemakers without risking an allergic reaction to sulfites.

Which of the following is an assumption on which the argument depends?

(A) These winemakers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine.

(B) Not all forms of sulfite are equally likely to produce the allergic reaction.

(C) Wine is the only beverage to which sulfites are commonly added.

(D) Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.

(E) Sulfites are not naturally present in the wines produced by these winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.


Edit: This is from ETS paper test, retired GMAT Q.


Note:
1. There is another question, which is almost same to this one, has only last two options interchanged. This particular question here is from OG and the official one. Other one, where option D and E are interchanged, might be from MGMAT.
2. Some people discussed on the OG question and some people discussed on the MGMAT question. Please observe the reference while reading through the thread.
For OG, answer is E and for MGMAT answer is D -- text content of these two are the same though.

3. With the similar stimulus, there is a different question (weaken question) from GMAT Prep -- that is discussed in:

E is the one.

Conclusion: people who want to drink and are allergic to sulphites can drink without risking an allergic reaction to sulfites

Negate E: Sluphites already present in the wines. So conclusion is wrong.

D is distantly possible. But it makes a statement about allergies in general, while the conclusion is specifically about sulphite allergies!

E ... straight answer ... it clearly assumes that sulphites are not naturally present in those wines in which the winemakers doesnot add sulphites ...

to weaken the argument u can also read it as since sulphite is naturally present in those wines so the winemaker doesnot add sulphite to it .

From this statement :"since there are several wine makers who add sulfites to none of the wines they produce,"
Iam assuming winer manufacturers are not adding sulfites, Iam going with A

I definitely think D. A is totally irrelevant. yes you have to assume they can preserve the wine by other methods. But you do not have to assume that to follow or believe the argument. I think its a red herring.

The argument is "If they dont add sulfites you can drink wine, even if you are allergic to sulfites"

or Like saying " If you are allergic to peanut butter you can eat it, as long as they dont add peanuts to it. Well, no you cant eat it, youll go into anaphalactyic shock.

hence the answer is D. We need to know that wine does not naturally contain sulfites.

No other answer make sense to me.

Please explain why D is not the right answer?


Come test day, i prolly would have picked D as well for times sake.

Now look closely @ D. there are no substances commonly present in wine that give rise to an allergic reaction. This is irrelevant because we are concerned about the people ONLY alergic to sulfates. just b/c the wine may or may not contain other alergenic substances is not a necessary assumption here.


A: has the same problem as D.
B: Irrelevant. Maybe not all but some do produce an alergic reaction. This doesn't gurantee that people who drink these wines will not have an alergic reaction. Again its irrelevant b/c it doesn't help us understand why the wine is ok to drink.
C: irrelevant we are talking about why wine is ok to drink.


I say E. B/c this eliminates the possibility of sulfates being present in the wine through additional means. Notice the passage discusses only that some wine makers don't add sulfates. What if sulfates were already in the wine naturally. This is an assumption the argument must rely on to be true.

Argument holds on the assumption that if no sulfites added by wine makers there are no sulfites in wine at all.Only E for me


but what is there to assume.
because, only if it is known that sulphites are not present in large amounts reqd for the drink, only then will they add an external source of sulphite.

ok to make things more clear its like this:-

say u are the wine manufacturer. you decide to make wine and add sulphite to preserve. Before doing so, you will, on introspection find that there is no reqd qty sulphite in the wine and then only add the reqd amt of sulphite.
supppose you knew that sulphite is already there in the wine , then the sulphite so present in the quantities iteself enough to preserve. so why do u want to add an external source? remove the source you will say. but here the external source is present . that means what? that means that there is already sulphifte present, and you , who is making the wine is aware about it. otherwise why will u ask external sulphite to be added?u already know that there is no sulphite, so what are u assuming?


what do u think??

Yeah, I chose D as well. It was really clear actually. You see, the argument made its conclusion so logically. There is no gap in its logic. Everything went smoothly from the premise to the conclusion. So our assumption here will not be required to fill a gap because we don't have any gap. The assumption we're looking for must attack any answer choice that could weaken the argument.

When the argument concludes that the lack of sulfites in wine will prevent people from getting any allergic reaction, we have a causal argument here. The causal here is that sulfites cause allergic reaction. Our assumption will attack any answer choice that could weaken this conclusion. In order to weaken this conclusion, an alternative cause to the effect can be raised. Our assumption must attack any alternative causal relation to this logic.

Option D, the assumption has attacked an alternative cause to the same effect. If this assumption is not true, then our conclusion will weaken the argument. so this is the correct answer.

Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives. However, since there are several wine makers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites.

Which of the following is an assumption on which the argument depends?


Explanation:
--------------------
A.) These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine. ---> Not sufficient. Why?

It's clear from the option that they are not adding sulfites; they are actually using some non-allergenic substances, but what if sulfites are naturally present in wines? What if this quantity of naturally present sulfites in wine is sufficient enough to cause allergic reactions?

So, discard this option.


B.) Not all forms of sulfite are equally likely to produce the allergic reactions. ---> This does not say anything about wine produced by wine makers who do not add sulfites. Discard this too.


C.) Wine is the only beverage to which sulfites are commonly added. ---> Irrelevant. Moreover, use of extreme word only.


D.) Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines. --->

To test if a statement is an assumption required for an argument, try to negate it. If the argument falls apart, it means the argument requires that assumption.

Here, if we negate option D, we get:
Sulfites are naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines.

It's quite clear that in view of the above statement, the conclusion will definitely fall apart.


E.) Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction. ---> This is wrong because we have to look for allergic reactions caused by sulfites only.

Just refer to the following parts in the excerpt: ...but are allergic to sulfites...without risking an allergic reaction to sulfites

whereas option E focuses on simply allergic reaction, NOT specifically allergic reaction due to sulfites.

Hence, I discarded this option.

For a moment, even if we assume it to be correct, it's still not as strong as option D.
--------------------

My choice is option D. Hope that helps.

This was a really good question reply2spg! I found option A really tough to reason. +1 to you.

Technext

(E) Sulfi tes are not naturally present in the wines produced by these winemakers in amounts large enough to

how to descriminate b/w D and E. The OA is given below, why not D


Assumption question: Find the conclusion. See what is essential to it. If stuck between two options, use assumption negation technique (ANT).
Let me first remind you that an assumption is a necessary missing premise. It is essential to the conclusion. If assumption becomes false, conclusion becomes false too (that is why ANT works. Negate the assumption, conclusion goes for a toss)

Conclusion: people allergic to sulfites can drink wines produced by these winemakers (those who do not add any sulfites to their wine)
without risking an allergic reaction to sulfites

i.e. if a winemaker does not add sulfites, you will not suffer from a sulfite allergic reaction by drinking his wine.
My question here is, isn't it an assumption that sulfite is not naturally present in wine even if it not added. May be grapes have it, may be during fermentation it is formed. The point is, we don't know whether it is naturally present. So if the argument says that a winemaker doesn't add sulfites so you will not suffer from a sulphites reaction, he is assuming that sulfites are not already present.
If you want to negate option E and see,
Negated (E) - Sulfites are naturally present in the wines produced by these winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.
If this is true, our conclusion falls apart. Hence this is the assumption.

Now why is D not correct?
(D) Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.

The conclusion says - You will not suffer an allergic reaction from sulfites. It doesn't say - You will not suffer any allergic reaction. Even if there are other substances that give rise to allergic reactions, you will still not get an allergic reaction from sulfites. So this is not an assumption.

E. Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction


The assumption type is logic gap. An assumption is the hidden premise. i.e. an assumption is what is absolutely necessary for the conclusion to be true. Without the assumption, the argument dies.

So what do the premises say here? note the underlined key words.
PRemise 1: May people suffer an allergic reaction to certain sulphites. which include those that are added as preservatives in wines.
Premise 2: some winemakers do NOT add them.
Conclusion: Hence, people who are allergic to sulphites can drink these wines without risking a reaction.

Where is the hole in the argument?
It jumps from no sulphites added = no sulphites present.
What does this imply?
That apart from adding sulphite preservatives, nothing else is a source of sulphites in wine.
Choice E correctly describes this.
Note that the choice E is a narrower version of the actual assumption here. However, an assumption is necessary but not sufficient for the conclusion to hold. Here, it might be possible that some other compound reacts in wine and forms the sulphites. In this case, the conclusion will not hold. However, the choice E is necessary to be true for the conclusion to hold. There are many assumptions on the GMAT that would be a narrower version of the actual assumption set.

E. Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction

Type: Choice D is correct. Natural presence is one of the many other sources of sulphites in the wine.
Choice E deals with general allergic reactions. The argument talks about reaction to sulphits. This choice is beyond the scope of the argument.

OA PLEASE.


OA is A.

D is not correct because the scope of the argument is confined to only sulfite allergy. The last sentence says ".... can drink these wines without risking an allergic reaction fo sulfites". Therefore, it is out of scope whether these consumers may be allergic to anything else present in the wine.

A is correct because if sulfites naturally occur in wine, ppl will have an allergic reaction to it even if sulfite is not synthetically added (to act as a preservative).

Hope that helps.

OG 12 says OA is E....Drinking wine to which no sulfi tes have been added will not prevent exposure to sulfi tes if, for instance, sulfi tes occur naturally in
wines. In particular, if the wines that do not have sulfi tes added have sulfi tes present naturally in quantities suffi cient to produce an allergic reaction, drinking these wines will not prevent an allergic reaction. Th e argument therefore depends on assuming that this is not the case. Source og 12.

The conlusion is : not adding sulfites to wine will prevent 100% from allergic reaction from what may suffer many people
But what if there are some others substances present in wine that may provoke allergic reaction ?
Choice E clarifies this, saying that apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.
Hence, E is the assumption we are looking for.

Hope that helps !

A good one and really touch to prethink.

Answer E

Premise1 :- Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives.

Premise2 :- there are several winemakers who add sulfites to none of the wines they produce.

Conclusion :- people who would like to drink wine but are allergic to sulfites can drink wines produced by these winemakers without risking an allergic reaction to sulfites.

Here it is very important to pay attentions to the bolded words. These words indicate that conclusion is limited for a small subset of people who are allergic to sulfites and who would like to drinks wine without risking allergic reaction ONLY to sulfites.

Here we can infer that we need not assume anything about 1) people who can allergic to sulfites by means other than wine 2) people who can allergic to any other substance present in wine

Now Let's Analyze the Answer Choice.

A) INCORRECT :- Very attractive shell game answer. But it is important to note that we are not concerned about allergic reactions of any other substances/preservatives in wine since the conclusion clearly states that without risking an allergic reaction to sulfites. So this choice talks about the 2nd group of people cited above.

B) INCORRECT :- we are discussing about the sulfites as a whole. So the reasoning such as Type A sulfite create allergic reactions and type 2 not is irrelevant here.

C) INCORRECT :- This choice discussed about 1st group of people cited above - who can allergic to sulfites by means other than wine

D) INCORRECT :- With change in words, this choice also talks about people cited above - who can allergic to sulfites by means other than wine

E) CORRECT :- Conclusion states that people can save from allergic reactions of sufites added in the wine by drinking the wine does no have sulfites added into it. But if the sulfites have already been present in those wines in natural form then the drinkers,who are allergic to sulfites, can have allergic reactions despite drinking such wines. SO we need to assume that the sulfites are not present in wines in natural form.

However, since there are several winemakers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these winemakers without risking an allergic reaction to sulfites.

Which of the following is an assumption on which the argument depends?

Conclusion: Sulphite Allergic people can drink wines produced by these winemakers without risking an allergic reaction to sulfites.
Why? Because winemakers are not using sulphite or not mixing sulphite.

(A) These winemakers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine.
This is already mentioned in premise. This provides no new information.

(B) Not all forms of sulfite are equally likely to produce the allergic reaction.
Out of scope. Nothing to do with forms of sulphite.

(C) Wine is the only beverage to which sulfites are commonly added.
Good...thank you very much. But not of my use.

(D) Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.
May be...But you are not asking me to find out those substance. I am only concerned with those people who are allergic to sulphite.

(E) Sulfites are not naturally present in the wines produced by these winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.
Yaa! Sounds good....So correct choice.


Hope this helps!

Hi Mohnish,

Sure,

The sentence basically says there are several winemakers who do not add sulfites to any of the wines they produce.

The following sentence draws a conclusion from that, that these wines are safe for people with suphide allergies to drink

Clear? Or was there something in particular that you wanted clarified further?
