rom Why We Love: The Nature and Chemistry of Romantic Love: Which of the following choices best explains why the author cannot say for certain how romantic love affects levels of serotonin in the brain? Question 19 options: a) There has not been a purely neurological study examining the relationship between the two. b) Some evidence suggests that romantic love increases serotonin and other evidence suggests it decreases serotonin. c) Serotonin does not have strong effects on the brain compared to dopamine and norepinephrine. d) There is a possibility that study subjects were not actually in love, but rather just suffering from obsessive-compulsive disorder.

I would say d. It is the only one I think explains itself well.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
