<p>Arctk3, I believe it had something to do with the bristled-haired incisors found on one but not the others.</p>
<p>Besides the fact that one of them has an an extra set of “teeth” that were actually stiffened bristles of hair, I think the only other thing different between all of them was their geographical location.</p>
<p>@Somewhere, it definitely asked what the DO have in common</p>
<p>Also, for the question on the social science passage I said that all of the animals have lower incisors… I didn’t say high concentrations of urine. I reread the passage via the link I posted and am still not sure of the answer. Can anyone help me out?</p>
<p>Here is how I got my answer on the what the rodents did have in common(At least I think the question asked of what they had in common)</p>
<p>The text to support my answer are
“The succulent green leaf tissues that remain still contain high levels of salt, but the rat’s specialized kidneys produce a highly concentrated urine that removes those salts.”</p>
<p>“it feeds on the saltbush; it scrapes salt crystals from leaves with its lower incisors; and its kidneys excrete a highly concentrated urine.”</p>
<p>“And like the North American kangaroo rat and the North African fat sand rat, the South American plains viscacha rat also proved to have kidneys that produce highly concentrated urine.”</p>
<p>Each one of these text describe each one of the rodents of having high level of urine.</p>
<p>Though at this point I’m not sure it was incisors or urine since I think they’re both right and I did get stuck on this question xD</p>
<p>it could not have been what they DID have in common because all three had highly concentrated urine, lower teeth or whatever, and upper teeth (cant remember name). THe only thing they didnt have in common was the hair bristles.</p>
<p>Anybody else still thinking it asked which of the following they did NOT have in common?..</p>
<p>^^^^^^^^^^^</p>
<p>I believe it was what they DID have in common. I chose urine.</p>
<p>Could have the question been along these lines(I’m going on a limb here)</p>
<p>Despite their geographical differences, what did all three rodents have in common?</p>
<p>I really do think it was highly concentrated urine because of what I posted above, the fact that since one rodent had the hair bristles and a scientist thought it was like the upper incisors, I eliminated that answer, but who knows, we have to wait for our scores to come in.</p>
<p>Right now it’s 3 saying what they DID have in common while 3 saying the question asked what they did NOT have in comon…anybody else?</p>
<p>i could easily be wrong, but the only difference betweent them was the hairs… everything else they were the same in (except Geographically)</p>
<p>because the passage describes that they have the same fangs or whatever but the difference is that the one had hair to scrape the salt off</p>
<p>Fairly certain you guys are both talking about two different questions. One question was the urine for an answer another was the hairs/upper jaw or w/e</p>
<p>Moving onto another topic, for the constitution passage</p>
<p>did anyone else get the answer of where it asked what did Philadelphia DID NOT have in common with Maryland was the aristocracy of Maryland since Maryland was plantation owners and Philadelphia was made mostly of farmers?</p>
<p>aristocracy- positive that was the answer</p>
<p>@Macaronin ya know Mac you might just be right xD</p>
<p>Cause the other question that involved the bristles hair was the one that asked what was the scientist surprised about the South American plains viscacha rat? I put that he was surprised about how fast the rat ate the salted leaves because of how when he said that he phrased it as a question</p>
<p>“As I gathered up the bits, I was astonished to find that they were the salt covering of the leaves. How did the rodent manage to strip the salt from the leaves so quickly?” - Direct quote from the passage</p>
<p>But it was also as likely to be the bristles hair because of this text</p>
<p>" But remarkably, in the soft tissue of the mouth, the animal appeared to have an extra pair of upper incisors, something no one had noticed while preparing the few museum specimens."</p>
<p>I am 100% sure it was what they did have in common. It couldn’t be what they didn’t because not all had the upper teeth things or the hair bristles… check the passage for proof.</p>
<p>yup arc thats what i remember. cus the bristled hair allowed it to clean the salt off or w/e fast. The other answer was the urine thing.</p>
<p>So what do you guys think is the answer for what the scientist was surprised at?</p>
<p>How fast the rodent ate the leaves or the fact it has those bristles hair?</p>
<p>Scientist was surprised at how fast the rat was able to eat the salted leaves.</p>
