Hi MartyMurray

can you please confirm that the reason for elimination of (B) is that, we cannot deduce whether people are mistaken about their belief regarding Lasagnas? with Lester Lasagna being an exception (in that it contains no fat when Lasagnas in general contain fat)

therefore, since people are not mistaken about their belief about lasagnas in general, this act of not labelling Lester lasagna as non fat is in line with the given condition?


Please, can any expert clarify this?

Food labeling regulation: Food of a type that does not ordinarily contain fat cannot be labeled “nonfat” unless most people mistakenly believe the food ordinarily contains fat. If most people mistakenly believe that a food ordinarily contains fat, the food may be labeled “nonfat” if the label also states that the food ordinarily contains no fat.

Which one of the following situations violates the food labeling regulation?

(A) Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled “nonfat.”
(B) Although most people are aware that lasagna ordinarily contains fat, Lester’s Lasagna, which contains no fat, is not labeled “nonfat.”
(C) Although most garlic baguettes contain fat, Lester’s Garlic Baguettes are labeled “nonfat.”
(D) Although most people are aware that applesauce does not ordinarily contain fat, Lester’s Applesauce is labeled “nonfat.”
(E) Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says “This product, like all salsas, is nonfat.”

Food labeling regulation: Food of a type that does not ordinarily contain fat cannot be labeled “nonfat” unless most people mistakenly believe the food ordinarily contains fat. If most people mistakenly believe that a food ordinarily contains fat, the food may be labeled “nonfat” if the label also states that the food ordinarily contains no fat.

Reviewing the regulation, we see that it require the following for labeling “nonfat” food of a type that does not ordinarily contain fat:

- Most people mistakenly believe the food ordinarily contains fat.

- The label also states that the food ordinarily contains no fat.

Which one of the following situations violates the food labeling regulation?

The correct answer will describe a situation that constitutes a violation of the regulation. So, presumably, the situation will involve a food that does not ordinarily contain fat, and that food will be labeled in a way such that one or both of the requirements are not met.

(A) Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled “nonfat.”

The regulation does not require any foods to be labeled “nonfat.”

So, the fact that the bran flakes are not labeled “nonfat” does not constitute a violation of the regulation.

Eliminate.

(B) Although most people are aware that lasagna ordinarily contains fat, Lester’s Lasagna, which contains no fat, is not labeled “nonfat.”

The regulation does not require any foods to be labeled “nonfat.”

So, the fact that the lasagna is not labeled “nonfat” does not constitute a violation of the regulation.

Eliminate.

(C) Although most garlic baguettes contain fat, Lester’s Garlic Baguettes are labeled “nonfat.”

The regulation applies to "food of a type that does NOT ordinarily contain fat."

Since the statement "most garlic baguettes contain fat," means that garlic baguettes DO ordinarily contain fat, the regulation does not apply to Lester's Garlic Baguettes.

Eliminate.

(D) Although most people are aware that applesauce does not ordinarily contain fat, Lester’s Applesauce is labeled “nonfat.”

By saying, "most people are aware that applesauce does not ordinarily contain fat," this choice indicates that applesauce does not ordinarily contain fat. After all, for people to be "aware" that applesauce does not ordinarily contain fat, it must be the case that applesauce does not ordinarily contain fat.

The regulation is that "food of a type that does not ordinarily contain fat," which applesauce is, cannot be labeled “nonfat” unless most people mistakenly believe the food ordinarily contains fat," which, as this choice indicates, most people do NOT believe.

So, labeling Lester’s Applesauce “nonfat” is a violation of the regulation since the requirement that people mistakenly believe that applesauce ordinarily contains fat is not met.

Keep.

(E) Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says “This product, like all salsas, is nonfat.”

By saying, "most people mistakenly believe that salsa ordinarily contains fat," this choice indicates that salsa does not ordinarily contain fat. After all, for people to "mistakenly believe" that salsa contains fat, it must be the case that salsa does not ordinarily contain fat.

At the same time, labeling Lester’s Zesty Salsa “nonfat” does not constitute a violation of the regulation because the regulation is that food of a type that does not ordinarily contain fat cannot be labeled “nonfat” UNLESS two conditions are met.

In other words, such a food CAN be labeled “nonfat” if the following two conditions are met:

- Most people mistakenly believe the food ordinarily contains fat.

- The label also states that the food ordinarily contains no fat.

This choice says that "most people mistakenly believe that salsa ordinarily contains fat" and that the label on Lester’s Zesty Salsa indicates that "all salsas" are nonfat, meaning that it "states that the food ordinarily contains no fat."

Thus, the labeling of Lester’s Zesty Salsa meets both requirements and thus complies with the regulation.

So, what this choice presents is not a violation.

Eliminate.

Correct answer: D

Food labeling regulation: Food of a type that does not ordinarily contain fat cannot be labeled “nonfat” unless most people mistakenly believe the food ordinarily contains fat. If most people mistakenly believe that a food ordinarily contains fat, the food may be labeled “nonfat” if the label also states that the food ordinarily contains no fat.

Which one of the following situations violates the food labeling regulation?

(A) Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled “nonfat.”
(B) Although most people are aware that lasagna ordinarily contains fat, Lester’s Lasagna, which contains no fat, is not labeled “nonfat.”
(C) Although most garlic baguettes contain fat, Lester’s Garlic Baguettes are labeled “nonfat.”
(D) Although most people are aware that applesauce does not ordinarily contain fat, Lester’s Applesauce is labeled “nonfat.”
(E) Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says “This product, like all salsas, is nonfat.”
The core of this problem lies in identifying which situation directly contradicts the given food labeling regulation.
Let's break down the regulation into its key components:

Rule 1: If a food does not ordinarily contain fat, it cannot be labeled "nonfat".
Exception to Rule 1: Unless most people mistakenly believe the food ordinarily contains fat.

Rule 2 (for the Exception): If most people mistakenly believe the food ordinarily contains fat, it may be labeled "nonfat" IF the label also states that the food ordinarily contains no fat.

The options can be examined against these rules:

Option (A): "Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled 'nonfat.'"
This aligns with Rule 1. Since people know it doesn't contain fat, it cannot be labeled nonfat. Not labeling it nonfat is compliant.

Option (B): "Although most people are aware that lasagna ordinarily contains fat, Lester’s Lasagna, which contains no fat, is not labeled 'nonfat.'"
The regulation specifies when a food cannot be labeled nonfat or may be labeled nonfat under specific conditions. It doesn't require labeling a truly fat-free product as nonfat. This situation doesn't violate the rule.

Option (C): "Although most garlic baguettes contain fat, Lester’s Garlic Baguettes are labeled 'nonfat.'"
The regulation doesn't directly address a situation where a food ordinarily contains fat but a specific product does not. It focuses on foods that ordinarily do not contain fat. This does not violate the regulation based solely on the provided text.

Option (D): "Although most people are aware that applesauce does not ordinarily contain fat, Lester’s Applesauce is labeled 'nonfat.'"
This is a direct violation of Rule 1. Applesauce does not ordinarily contain fat, and most people are aware of this. Therefore, it cannot be labeled "nonfat."

Option (E): "Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says 'This product, like all salsas, is nonfat.'"
This aligns with the exception and Rule 2. Most people mistakenly believe salsa ordinarily contains fat, and the label clarifies that it ordinarily contains no fat ("like all salsas, is nonfat"). This is compliant.

Therefore, the situation that violates the food labeling regulation is (D).

Can some expert please help with the sufficient and necessary conditions here

As per statement 1,
for food to be labeled non fat , it is required people mistakenly believe it contains fat

but as per 2nd statement,
"people mistakenly believe" is placed after "if" making it a sufficient condition

so as per this statement, the arrow reverses

If people mistakenly believe food contains fat ---> label food non fat

also how to deal with double "if's" here ? " if the label also states that the food ordinarily contains no fat"

If someone could share their insights, would be a great help

Thank you so much

First, it's important to note that they never give us a condition that involves ACTUALLY labeling anything. It's all about what we CAN do, not what we must/should/will do.

1st conditional: Label NF --> Most believe F

This gives us one requirement for labeling something nonfat. If you want to use that label, it needs to be on something people believe normally has fat. So if people DON'T have this belief, we can't use the label, even for a truly nonfat food. Notice that this never tells us when we CAN use the label! There may still be other requirements. (Similarly, if I say you can't vote unless you're 18, that doesn't mean that someone who is 18 can/will vote. Maybe they're not registered, etc.)

2nd conditional: Most believe F --> Can label F (w/ extra condition)
You could also write this with both conditions combined in the sufficient: Most believe F + warn people that normally no fat --> Can label F

This adds what the 1st was missing. If most people believe (incorrectly) that the food normally has fat, then you CAN use the nonfat label.
It might look odd to chain these together -- Label NF --> Most believe F --> can label NF -- since it's weird to go from "I labeled this" to "I can label this." It might make more sense to look at this as a form of biconditional (X-->Y and Y-->X, or X<-->Y). It's telling us that if people DON'T have this belief, you can't label, but if they do, you can. It's kind of like saying "You can't vote unless you're 18, but if you're 18, you can vote (as long as you register)." In other words, there are no other requirements than what they've mentioned.

You just cleared my doubt

The fact that this is a biconditional ( X<-->Y) makes more sense now

If people are mistaken --> label non fat

Label non fat --> people are mistaken

The other if conditions are just a paraphrase of this core idea

Thank you again!

(A) Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled “nonfat.”

(E) Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says “This product, like all salsas, is nonfat.”

It is an interesting question. The intent behind the regulations will help us understand them better. The intent is that the food manufacturers should not be able to misguide the public.

So these are the regulations:
- If a food doesn't ordinarily contain fat, you cannot label it “nonfat” (else some manufacturers may try to misguide the public that normally salsa has fat but ours doesn't so buy ours by labelling 'non fat')
Exception to this rule: Only if most people mistakenly believe the food ordinarily contains fat, then you may be able to label it non fat. (people mistakenly believe that this food has fat is necessary for non-fat label, but it may not be sufficient)

- If most people mistakenly believe that a food ordinarily contains fat and if your label states that the food ordinarily contains no fat, then the food may be labeled “nonfat” .
If these two conditions are met, then they are sufficient to label the food non-fat.

So the regulations say very simple things: If the food doesn't contain fat normally, DO NOT write non-fat on it. Don't try to mislead people that this food contains fat but our brand doesn't.
If people falsely believe that this food contains fat normally, and if you tell them that this food does not normally contain fat, then you can write non-fat on your product. So they know that all brands of this food has no fat including this brand. In that case the label doesn't give the false impression of this brand being better than others.


(A) Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled “nonfat.”

We are not given that we must label non-fat in any circumstance. The regulations only talk about when one is ALLOWED to label something non-fat. Hence this is beyond the scope of regulations.


(B) Although most people are aware that lasagna ordinarily contains fat, Lester’s Lasagna, which contains no fat, is not labeled “nonfat.”

Same as above. We are not given that we must label non-fat in any circumstance. The regulations only talk about when one is ALLOWED to label something non-fat. Hence this is beyond the scope of regulations.

(C) Although most garlic baguettes contain fat, Lester’s Garlic Baguettes are labeled “nonfat.”

We are not the regulations when food actually does contain fat. Our regulations only talk about food of a type that does not ordinarily contain fat. Hence this is beyond the scope of regulations.

(D) Although most people are aware that applesauce does not ordinarily contain fat, Lester’s Applesauce is labeled “nonfat.”

To label something non-fat, most people MUST mistakenly believe the food ordinarily contains fat. This necessary condition is not met for applesauce since most people are aware that applesauce does not ordinarily contain fat. Hence Lester’s Applesauce non-fat label is against the regulations.
Correct.

(E) Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says “This product, like all salsas, is nonfat.”

Two conditions are sufficient to label salsa (non fat food) as non-fat. These are: "most people mistakenly believe that it ordinarily contains fat" and "your label also states that the food ordinarily contains no fat"
We are given that both conditions are met by Lester's Zesty Salsa. Most people mistakenly believe that salsa ordinarily contains fat and the label specifies "like all salsas."
Hence it meets the regulations.

Answer (D)
