The correct answer is option D: "All of the above". This is due to the fact that Ketamine (also known as Special K), Dextromethorphan and Phencyclidine (also known as PCP or Angel Dust) are dissociative drugs that can cause all of the effects mentioned when used at higher doses. When a drug is dissociative, it means they can cause auditory and visual distortions (like hallucinations) and they do so by altering the actions of a brain chemical called glutamate at certain types of receptors that are specific for glutamate called: N-methyl-D-aspartate (NMDA) receptors that are located in various parts of the body, specifically on nerve cells throughout the brain.

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.

Read this excerpt from i never had it made. "it's all that ought to count," he replied. "but it isn't. maybe one of these days it will be all that counts. that is one of the reasons i've got you here, robinson. if you're a good enough man, we can make this a start in the right direction. but let me tell you, it's going to take an awful lot of courage." he was back to the crossroads question that made me start to get angry minutes earlier. he asked it slowly and with great care. "have you got the guts to play the game no matter what happens? " "i think i can play the game, mr. rickey," i said. the next few minutes were tough. branch rickey had to make absolutely sure that i knew what i would face. beanballs would be thrown at me. i would be called the kind of names which would hurt and infuriate any man. i would be physically attacked. could i take all of this and control my temper, remain steadfastly loyal to our ultimate aim? which is the central idea of this excerpt?

In at least 150 words, discuss the comparison described in the figurative language and how the connotative language reinforces the symbol. certainly the utmost rim of my first dome was filled with the tumultuous impression of soldiers marching to death for freedom's sake, of pioneers streaming westward to establish self-government in yet another sovereign state. only the great dome of st. peter's itself has ever clutched my heart as did that modest curve which had sequestered from infinitude in a place small enough for my child's mind, the courage and endurance which i could not comprehend so long as it was lost in "the void of unresponsible space" under the vaulting sky itself.
