<p>Words and phrases concerning concepts of left and right permeate our language and thinking: The right hand (meaning also the left hemisphere) is strongly connected with what is good, just, moral, proper. The left hand (therefore the right hemisphere) is strongly linked with concepts of anarchy and feelings that are somehow out of conscious control-somehow bad, immoral, dangerous.</p>
<p>The phrases in parentheses in the first paragraph primarily serve to:
(A) compare the strength in a person's hands to that of the hemispheres in his brain
(B) outline the pathway by which signals balances the impulses i the left and right hemispheres
(C) demonstrate how the brain balances the impulses in the left and right hemispheres
(D) highlight the main differences between the left and right hemispheres of the brain
(E) indicate the areas of the brain responsible for moving each side of the body</p>
<p>The answer is E! Why? I picked D because I didn't think the "right hand" and "left hand" mentions were literal? </p>
<p>No, those parentheses simply add further information of which side of the brain responsible for each hand.
Right hand = left side, left hand = right side. As simple as that.</p>
<p>The passage is not talking about the differences of the sides of the brain but about the symbolic concepts linked with each side of the body. Right = good, left = bad. Thus you can treat the parentheses nothing more than digressing informations.</p>
<p>But what about the “moving each side of the body part”? I don’t understand how that could be right?</p>
<p>Another question: The scientific analysis of a text-how mind and a hand conspire to commit acts of writing- can reveal features as sharp and telling as anything this side of fingerprints and DNA. Although we disguise our writing voice, it can never be fully masked. After the crime, words remain. Like fingerprints and DNA.</p>
<p>The author compares “our writing voice” to "fingerprints and “DNA” in order to
(B) assert that all three are impossible to erase
© imply hat all three may be difficult to conceal</p>
<p>I know B is an extreme answer, but the author does say that our writing can “NEVER be fully masked.” Why is the answer C?</p>
<p>hmm yeah, you may be right,
We know that those areas are reponsible for each specific side but that is indeed self-knowledge. But the answer also cannot be the others, are there any other places of the passage mention this information? </p>
<p>I think I will get a zero on SAT!!! UFFFF I don’t get any of them right…</p>
<p>well, “masked” = “concealed”, NOT “erased”. Period.</p>
<p>Okay so It’s litterally talking about “(meaning the left hemisphere).” It’s giving more info on that. That’s why it is E</p>
