According to a study, after a week of high-altitude living, twenty men had slimmed down. The men, middle-aged residents of low-altitude areas, had been taken to a research station at 2,650 meters (8,694 feet) above sea level. They had unrestricted access to food and were forbidden vigorous exercise, yet they lost an average of 1.5 kilograms (3.3 pounds) during their one-week stay. Clearly, the lower availability of oxygen at higher altitudes, or hypobaric hypoxia, can be said to have caused the weight loss, since __________.

Which of the following would, if true, most logically complete the argument?

A. a decrease in oxygen intake has been shown to depress appetite
B. the men all participated in the same kinds of exercise during their stay
C. the foods available to the men had fewer calories than the foods they usually ate
D. exercise at higher altitudes is more difficult than exercise at lower altitudes is
E. several weeks after returning home, the men still weighed less than they had before the study

Concluded from the argument, twenty middle-aged men of residents of low altitude areas were taken to a high altitude area of 8694 feet above sea level for one week. It was reported that they lost weight during their stay there even when they had unlimited access to food, and were also forbidden vigorous exercise.

So, let's examine each option for the most relevant assumption to validate the reason for their weight loss in the argument.

Option A - Correct
This answer choice proves a strong point in logically completing this argument since the lower availability of oxygen at higher altitudes was said to be the cause of their weight loss. Hence, this decrease in oxygen has been down to reduce appetite. Therefore, it is the most relevant option to complete the argument. Hence, it is correct

Option B - Incorrect
The argument mentioned that they were forbidden vigorous exercise, and there is no certainty if all of them participated in any exercise because it wasn't compulsory.

Option C - Incorrect
This answer choice is wrong because they had unlimited access to get food that suits their preference.

Option D - Incorrect
There is no backing from the passage to validate this claim on if exercise at higher altitudes is more difficult than exercise at lower altitudes. Hence, this option is rendered invalid.

Option E - Incorrect
This is irrelevant to what could be the cause of their weight loss.

According to a study, after a week of high-altitude living, twenty men had slimmed down. The men, middle-aged residents of low-altitude areas, had been taken to a research station at 2,650 meters (8,694 feet) above sea level. They had unrestricted access to food and were forbidden vigorous exercise, yet they lost an average of 1.5 kilograms (3.3 pounds) during their one-week stay. Clearly, the lower availability of oxygen at higher altitudes, or hypobaric hypoxia, can be said to have caused the weight loss, since __________.

Conclusion : The lower availability of oxygen at higher altitude can be said to have caused the weight loss.
Premise ..
1. The people undergo in the study were having unrestricted access to food and were forbidden vigorous exercise
2. Yet they lost on an average of 1.5 kilogram .

let's analyse..
In what scenario the availability of oxygen cannot be said to have cause the weight loss.
given
1. The people undergo in the study were having unrestricted access to food and were forbidden vigorous exercise
2. Yet they lost on an average of 1.5 kilogram .

What if lower availability of oxygen does not have any relation with respect to the weight loss..
In that case our belief of lower availability of oxygen lead to weight loss will be weeken .
so our assumption is
1. Lower availability of oxygen does help in some way for the weight loss .

POE

Which of the following would, if true, most logically complete the argument?

A. a decrease in oxygen intake has been shown to depress appetite
1. If this is the case then and it will increase or belief that lower availability of oxygen will lead to decrease in appetite and can be an explanation for lower consumption of calories and then a reason for weight loss.. Correct
B. the men all participated in the same kinds of exercise during their stay

1. This choice does not impact or conclusion.. Hence incorrect

C. the foods available to the men had fewer calories than the foods they usually ate

1. Argument says that people were having unrestricted access to food sources, hence this choice is not relevant to the conclusion.. Hence incorrect

D. exercise at higher altitudes is more difficult than exercise at lower altitudes is

1. The argument says that people were forbidden of any vigorous exercise at higher altitude.. So whether exercise is more difficult or not is out of scope of conclusion.. Hence incorrect


E. several weeks after returning home, the men still weighed less than they had before the study

1. Out of scope of conclusion.. Hence incorrect

A is the best choice and that is our answer.
