Answer:
D Serotonin levels, because this is the variable she is measuring .
Explanation:
Dr. Whitlock is looking for the effectiveness of the medication.
A. is incorrect because it say the type of medicationn was being manipulated if this were true this would be the independent variable (the thing the scientist or person changes)
So just by knowing why A is wrong we can automatically rule out
A.
C. and
E.
That leaves B. and D. giving you 50/50 chance of being correct if this were on an actual test/EOC.
I am a little unsure of if it would be B or D at first so I decided to leave some information for you in case you disagree or want to check I'll leave it up to you to officially decide if it's B or D but I personally believe it's D. here's the information:
You can Eliminate B. because Dr. Whitlock is looking for the effectiveness of the medication and D. is talking about the serotonin levels, serotonin affects your mood, low serotonin levels can cause depression. But if serotonin effects your mood is that something a anti-psychotic medicine be prone to fixing or would it be the hallucinations? which many experience but do the serotonin levels effect your sanity more than the auditory hallucinations, cause people can have inaudible hallucinations.
I may be looking into to this WAY too much and OVER thinking it but I hope this at least helped you a bit giving you a 50/50 chance of getting this right. Sorry if this is confusing.
( I found the same question but with the letter options thats how I know the options and how I ruled out some)
Answer:
The author's point of view is reflected in this phrase; "..., in the near future, the United States using the pretext of an allegedly growing threat to the Western Hemisphere, will embark on a long process of increasing the pressure on governments of the Latin American countries to work out additional threats against Cuba."
Explanation:
The author's perspective is seen in his use of words like "pretext," and "allegedly". The author is thus saying that the United States is not straightforward, or completely honest in the claims of a threat to the Western Hemisphere. This phrase also shows that the author believes that the United States was being unnecessarily hard on the Cuban nation by threatening them.
We can sense that the author of the text favors Cuba as against the United States. In order to determine the author's perspective, careful attention ought to be given to certain key words in the text.
