A recent study determined that individuals who fulfill the diagnostic criteria for depression have lower levels of blood oxygen saturation than do individuals who are not clinically depressed. The researchers who performed this study concluded that normal levels of blood oxygen saturation guard against the development of clinical depression.

The experimenters' conclusion depends on which of the following assumptions?

A Clinical depression does not cause individuals' levels of blood oxygen saturation to decrease.
B Individuals with clinical depression experience the same physical and mental symptoms as do individuals with a decreased supply of oxygen.
C High levels of blood oxygen saturation guard against the development of clinical depression more effectively than normal levels of blood oxygen saturation do.
D Individuals with normal levels of blood oxygen saturation cannot develop clinical depression.
E Treatments for blood oxygen saturation are more effective than treatments for clinical depression.

Is it A

If it is then i will try to explain my reasoning behind it.

better you explain i dont have oa now

E Treatments for blood oxygen saturation are more effective than treatments for clinical depression.

treatments is irrevelant thus E is incorrect
D is so extreme since the conlusion is just about " gaurd against"= help to oppose the clinical depression"
C seems to weaken.
B physical and mental symptoms is not mentioned thus out of scope
A left and A is my answer

Conclusion - normal levels of blood oxygen saturation guard against the development of clinical depression.

Only contenders A and D

A - Clinical depression does not cause individuals' levels of blood oxygen saturation to decrease. This is great contender and trap also. Let's say that Clinical depression does cause individuals' levels of blood oxygen saturation to decrease. How does it impact conclusion?

D - Individuals with normal levels of blood oxygen saturation cannot develop clinical depression. - Let's negate this - Individuals with normal levels of blood oxygen saturation can develop clinical depression. If normal levels can develop depression then how come those levels guard against depression?

D is correct
