People in isolated rain-forest communities tend to live on a largely

IMO B.

I think it should be B. First I pointed to D but close look on stem revealed that “however” is placed before “because”.

So stem is “salt is not culprit”, however, because ~some reason that shows salt indeed causes High BP~

There is a big context switch in this Q.

It talks about salt's effects on people living in RF and then talks about salt's effects on people in IC

Then it says Salt is probably not the cause of High BP ( both for people from RF and moved to IC and who are in IC for ever)

Then what it is the cause. Lets say it is B, that people who have been living in IC for ever has been getting this and its the reason. It does not explain how people who just moved into the city and eating salt diets are getting High BP

So, IMO B is incorrect. D says there are other aspects that can cause this.

BP: Blood Pressure.

Premise 1: People in rain forest consume less salt in diet. Few people suffer high BP, but their BP doesn't increase with age.
Premise 2: People whose BP doesn't increase with age, increase when they move to industrialized countries.

Between P1 & P2, Below are changes.
1. Change in environment.
2. Change in amount of salt in diet.

one of them could be the reason behind raising BP.

Last statement in the argument says that salt is not the culprit. So, passage can be concluded by telling the reason behind this. Only Option (D) states that.
A. genetic factors could account for the lack of increase of blood pressure with age among such people. Its third factor brought by this answer. so, out of context.
B. people eating high-salt diets and living from birth in cities in industrialized societies generally have a tendency to have high blood pressure. It can be correct. but, passage can't end with this. Its should end with saying reason, why salt is not culprit behind the high BP.
C. it is possible to have a low-salt diet while living in a city in an industrialized country. It tries to tell that Salt raises the BP.
D. there are changes in other aspects of diet when such people move to the city. Its the answer justifying that, Change in environment is the cause of high BP.
E. Salt is a necessity for human life, and death can occur when the body loses too much salt. First, we don't know if this is correct. Secondly, extra information and knowledge can't be used to end the passage.

People in isolated rain-forest communities tend to live on a largely vegetarian diet, and
they eat little salt. Few of them suffer from high blood pressure, and their blood pressure
does not tend to increase with age, as is common in industrialized countries. Such people
often do develop high blood pressure when they move to cities and adopt high-salt diets.
Though suggestive, these facts do not establish salt as the culprit in high blood pressure,
however, because ________.

General information about people in rain-forest communities: Diet and dieseases that dont bother them normally even with ageing.
The moment they move to cities, they often pick bp.
Key is the word: Deveop bp and though.

Conclusion is: Salt is not responsible for bp . This should have a premise that improves reliability of conclusion.
Thus, sentence after because bolsters conclusion that salt is not resposbile. Something else caused this.


A. genetic factors could account for the lack of increase of blood pressure with age
among such people == OFS: We are looking for reason for picking up bp . This gives opposite answer , the reason for not picking up bp.
B. people eating high-salt diets and living from birth in cities in industrialized
societies generally have a tendency to have high blood pressure --- OFS: This doesn't tell why settlers pick bp.
C. it is possible to have a low-salt diet while living in a city in an industrialized
country === Might be true: We dont know this.
D. there are changes in other aspects of diet when such people move to the city
==This is the correct reason suggesting that and strengthening conclusion that some other reason has caused the increase in bp.
E. salt is a necessity for human life, and death can occur when the body loses too
much salt
== Out of scope

Hi

Please clarify the following sentence construction:

"Though suggestive, these facts do not establish salt as the culprit in high blood pressure, however, because"

What is the significance of however in this sentence? Does is says salt is the reason or is it the opposite?

Pranav

"However" here is a contrast marker, and as a matter of fact redundant, because "though" already marks the contrast. If it were an SC sentence, it would probably be one of the wrong options.

Three ways to construct the sentence:

The facts suggest that salt is the culprit of high blood pressure. HOWEVER the facts do not establish the same.

THOUGH suggestive, the facts do not establish that salt is the culprit of high blood pressure.

The facts suggest that salt is the culprit of high blood pressure, BUT the facts do not establish the same.

Use of any 2 of the above 3 contrast markers (in upper-case letters) in a single sentence can be considered redundancy.

Though in manhattan this question is about conclusion but we need to state a reason and not conclude from the passase.
Which of the following most logically completes the argument given?

People in isolated rain-forest communities tend to live on a largely vegetarian diet, and they eat little salt. Few of them suffer from high blood pressure, and their blood pressure does not tend to increase with age, as is common in industrialized countries. Such people often do develop high blood pressure when they move to cities and adopt high-salt diets. Though suggestive, these facts do not establish salt as the culprit in high blood pressure, however, because ________.
A. genetic factors could account for the lack of increase of blood pressure with age among such people
No mention about the genetic factor in the premise.
B. people eating high-salt diets and living from birth in cities in industrialized societies generally have a tendency to have high blood pressure
This is the conclusion and a potential trap answer.
C. it is possible to have a low-salt diet while living in a city in an industrialized country
No mention about specific low salt diet in an industrialized country. They mention about high salt diet.
D. there are changes in other aspects of diet when such people move to the city
The other aspect concludes the last line which says that because of all these reason salt is not the main reason and so there has to be other reasons in the diet.
E. salt is a necessity for human life, and death can occur when the body loses too much salt
Out of scope.

Though suggestive, these facts do not establish salt as the culprit in high blood pressure, however, because ____________

(A) genetic factors could account for the lack of increase of blood pressure with age among such people
(B) people eating high-salt diets and living from birth in cities in industrialized societies generally have a tendency to have high blood pressure
(C) it is possible to have a low-salt diet while living in a city in an industrialized country
(D) there are changes in other aspects of diet when such people move to the city
(E) salt is a necessity for human life, and death can occur when the body loses too much salt

The answer is D

The argument discusses the lower incidence of high blood pressure in people living in isolated rain forest and the low salt diet of those people .There is a phenomenon that suggests that people in rain forest do not get high blood pressure with age .The argument then says that when such people move to cities they tens to suffer from high blood pressure .
The argument then says that such high blood pressure may not exclusively be due to salt .
Now we have to find an option that gives us more information apart from salt that can be a contributing factor to high blood pressure .

A is not irrelevant as nothing is discussed in the passage about genetics and even if such people more to cities they are not not going to suffer form high blood pressure as genes will not change .
B This does not give us any information regarding high blood pressure in people who have moved from rain forest to cities .
C It suggests that salt is the main reason that people suffer form high blood pressure .
D correct it suggests that there may be some more causes why people suffer from high blood pressure .
E out of scope

Main Group: Ppl from isolated rain-forest moved to cities and adopted high-salt diets.
Main Issue: Those ppl develop HBP after moved to the cities and adopted high-salt diets. BUT Salt is not the reason. WHY?



So How did they develop HBP after moved to the cities? Was that because of salt? (A) is out.


Wrong group. Cities ppl vs. rain-forest ppl. (B) is out

Wrong group again. Ppl who adopted high-salt diet vs. ppl who follow low-salt diet. (C) is out

This explains it. Something else other than Salt caused HBP. Hang on to this.

So Salt is the reason of HBP or not? (E) don't tell me any thing about that. You are out!

Only (D) is left. (D) is our answer.

Request you to elaborate on the correct answer as it is not clear as to why it is the one!
Thank you

basically we need to find out reasoning why is it said that it is not because of salt that people, who often don't get high blood pressure because of less salt diet , get high blood pressure when move to city.
If salt is not the reason then there could be some other reason for high blood pressure . Find out what ?
A is against the premise
B strengthens the claim
C doesn't explain then why have high blood pressure
D weakens the claim--this is what we need that other factor is responsible
E good for information but irrelevant

I hope it is clear

Hello GMAT Experts Bunuel GMATNinja MartyTargetTestPrep mikemcgarry

Hope you're keeping safe..!!

Can someone please help me understand the role of 'however' in the last sentence. Is it really presenting a contrast or is it really a non-essential modifier? I am unable to understand the meaning due to the presence of However + Because.

Thanks in advance!
Tilak

"However" tells us that the author has shifted to a contrasting point of view. Here, "however" comes after that shift -- the author first presents information that implies that salt IS the culprit, but then shifts to argue that "these facts do NOT establish salt as the culprit in high blood pressure, however."

Then the word "because" comes along, followed by the blank. This tells us that we need to fill in a reason why the author has made that shift.

So, we're looking for an answer choice that supports the argument that salt is NOT the culprit in high blood pressure.

(D) does exactly that -- it says that people change other aspects of their diets when they move to a city, so we can't confidently blame salt for the blood pressure issue.

I hope that helps!
