Colfax Beta-80 is a rare genetic defect found primarily in people of

Question

Colfax Beta-80 is a rare genetic defect found primarily in people of Scandinavian descent. Over 97% of known carriers of this defect have are citizens of, or are direct descendants of immigrants from, Denmark, Norway, and Sweden. People who carry the Colfax Beta-80 defect are at substantially higher risk for contracting Lupus and related autoimmune diseases.

Assuming the statements above are true, which of the following can be inferred from them?

(A) People from Denmark are at a higher risk for Lupus than people of other, non-Scandinavian countries.

(B) Genetic engineering that eradicated this genetic defect would constitute a de facto cure for Lupus.

(C) Find a cure for Lupus would eliminate most of the health threats associated with the Colfax Beta-80 defect.

(D) A person not of Scandinavian descent born with the Colfax Beta-80 defect is more likely to contract Lupus than is a Scandinavian who is born without this defect.

(E) The majority of people who contract Lupus are either Scandinavian or of Scandinavian descent.

D: as the line suggests: "People who carry the Colfax Beta-80 defect are at substantially higher risk for contracting Lupus and related autoimmune diseases." irrespective of descent it says the carrier of disease is at a higher risk and also the "Colfax" is genetic defect meaning it occurs at birth, so a person of Scandinavian descent not having this at birth is at a lower risk of contracting Lupus.

Rest all others can be eliminated except for A
A: Why I eliminated A was  People from Denmark  are at a higher risk for Lupus than people of other, non-Scandinavian countries.
these people can be of non-Scandinavian descent living in denmark, they are at a lower risk of contracting the disease as suggested by 97% second line afterwards. so eliminated. Let me know your views!

(A) People from Denmark are at a higher risk for Lupus than people of other, non-Scandinavian countries.  Eliminated  People of Denmark may not necessarily be citizens or descendants of Denmark/Scandanavian countries.

(B) Genetic engineering that eradicated this genetic defect would constitute a de facto cure for Lupus.  Eliminated  This statement necessity statement as sufficiency statement.

(C) Find a cure for Lupus would eliminate most of the health threats associated with the Colfax Beta-80 defect.  Eliminated  Again this statement takes specific information to generalization. The defect in gene is known to cause lupus, however, it ay be causal reason for several other defects/diseases. Hence may not eliminate most of the health effects associated with it.

(D) A person not of Scandinavian descent born with the Colfax Beta-80 defect is more likely to contract Lupus than is a Scandinavian who is born without this defect.  Suitable  The last statement of stem is "  People who carry the Colfax Beta-80 defect are at substantially higher risk for contracting Lupus and related autoimmune diseases  ". This indicates that the defect is the primary cause of lupus and not citizenship or ancestry. Hence, the presence of the genetic defect may indicate the likelihood and not the citizenship/ancestry.

(E) The majority of people who contract Lupus are either Scandinavian or of Scandinavian descent.  Eliminated  This is nowhere given in the stem. It has only been mentioned that majority of Scandinavian citizen carry the genetic defect. They may however be a minor share of global lupus incidence.

The passage states:
- Colfax Beta-80 is a rare genetic defect primarily found in people of Scandinavian descent.
- Over 97% of carriers are from Denmark, Norway, or Sweden.
- Carriers are at a substantially higher risk for Lupus and related autoimmune diseases.

Let’s evaluate the options:

(A) People from Denmark are at a higher risk for Lupus than people of other, non-Scandinavian countries.
- This is plausible because the defect is primarily found in Scandinavians, and carriers are at higher risk for Lupus. However, the passage does not explicitly compare risk levels between Scandinavians and non-Scandinavians.

(B) Genetic engineering that eradicated this genetic defect would constitute a de facto cure for Lupus.
- This cannot be inferred. The passage does not suggest that Colfax Beta-80 is the sole cause of Lupus, so eliminating it would not necessarily cure Lupus.

(C) Finding a cure for Lupus would eliminate most of the health threats associated with the Colfax Beta-80 defect.
- This cannot be inferred. The passage does not state that Lupus is the only health threat associated with the defect.

(D) A person not of Scandinavian descent born with the Colfax Beta-80 defect is more likely to contract Lupus than is a Scandinavian who is born without this defect.
- This can be inferred. The passage states that carriers of the defect are at a substantially higher risk for Lupus, regardless of their descent.

(E) The majority of people who contract Lupus are either Scandinavian or of Scandinavian descent.
- This cannot be inferred. The passage does not provide data on the overall prevalence of Lupus or its distribution among populations.

The most reasonable inference is (D).

Answer: (D)

Magoosh Official Explanation:

The prompt tells us that Colfax Beta-80 is a genetic defect. Most of the folks who have this defect are Scandinavian, but we don’t know what percent of Scandinavians have this defect. It may be a substantial portion, but that’s unlikely because the defect is “rare.” Much more likely: there only be a couple hundred people in the whole world who have this defect, and 97% of this couple hundred are from Scandinavia —- a large percentage among those with the defect, but not a large percentage among the Scandinavian population as a whole. A couple answer choices conflate these two percentages.

Anyone with this defect is at higher risk for Lupus and other autoimmune diseases.

(D) is the credited answer.   This more or less restates the information of the last sentence. Anyone with this defect (Scandinavian or not) has a substantially higher risk of Lupus compared to anyone without the defect (Scandinavian or not).

(A) & (E) play on the misunderstanding about what the 97% implies. Most folks with this genetic defect are Scandinavian, but that doesn’t imply that most Scandinavian people have this defect. People with the defect are at higher risk for Lupus, but that doesn’t mean large sections of the Scandinavian population are at risk for Lupus.

(B) is wrong because, while we are told this genetic defect causes susceptibility to Lupus, we don’t know what other factors might cause or contribute to Lupus. Just because we eliminate this one factor does not mean we would eliminate everything in the world that could possibly contribute to the onset of Lupus.

(C) is wrong because, while we are told this genetic defect causes Lupus, we are also told it causes other autoimmune diseases. Even if we had a cure for Lupus, these other autoimmune diseases would still poses health threats to carriers of the defect.
