<p>1 wasnt an option. and 1 isnt consider prime.</p>
<p>The answer was 2, because that is the only even prime number. When added to other prime numbers (which all have to be odd), even + odd = odd --- prime numbers HAVE to be odd after 2.</p>
<p>Oh shoot! i put 2! :( It was 11!! (i think)</p>
<p>ahh no. 2 + 7 = 9. and 9 isnt prime. but then again 3+2 = 5. and 5 is prime. but then u cant pick 2 and 3 which were both choices. So i just went with 11.</p>
<p>???
What was the question again?
Because 11 + 2 is the only way you can get a prime number...whereas 2 + a bunch of different prime numbers = prime number (ex. 2+3, 2+11, 2+29 etc)</p>
<p>And another thing to point out...the only example that works for 11 just so happens to involve the number 2.</p>
<p>i believe the question was if u add two prime numbers u get a prime number what must one of the prime numbers be? something to that extent</p>
<p>Ya, so the answer has to be 2.
Every counterexample against 2 = a counterexample against 11, but 2 has a lot more ways to make prime number sums.
2 is special, since its the only even number in the set of prime numbers, and since being prime requires the number to be ODD + the set of prime numbers are all ODD except 2, when you sum two random prime numbers together, in order to get another prime, it has to be ODD at the very least (not necessarily prime). 2 is the only number that can meet this precondition since it is EVEN, and EVEN + ODD = ODD, at least giving the sum a chance to be prime.</p>
<p>but 2+7 = 9</p>
<p>i put 2.....</p>
<p>I did choose 2! Yes, it all comes back to me now.</p>
<p>Ohh this is making me nervous.</p>
<p>2 makes a lot more sense now. but 2+7=9 made me not pick 2. Anyway wats like a -5 on math?</p>
<p>I'm guessing a 31-32.</p>
<p>noooooooooooooooooooooooooo</p>
<p>i need a 31 composite man. Hey guys was just me or was the science/reading like straightforward with no tricks. and one more... for geese = more fecal stuff rite cause they are endotermeic. but how is a test takes suppose to know a geese are endothermic.</p>
<p>^ common sense? Because the passage implied that the fecal whatever in the water wasnt supposed to be there...geese don't live underwater...so I just assumed they were endothermic.</p>
<p>I think they write the science section to **** off analytical geniuses.</p>
<p>"geese don't live underwater...so I just assumed they were endothermic." </p>
<p>that part requires some outside knowledge. ACT isnt suppose to test if you know geese live under water or not.</p>
<p>i was rite then rite the fecal increases ........</p>
<p>It said in the explanation that Geese are ethodermic.</p>
<p>k trixee that explains everything i dont read the explanations i was short on time. however at the end i finished the science section 1 min early. thx for clearing things up trixee.</p>
<p>LOL guys the answer is 2. It didn't say that every time you added the two prime numbers you get a prime (that is imposible with any number), just that you would get a prime if you added this prime to another. Its 2 because that is the only prime number that can be added to 3 and get 5, also a prime number.</p>
<p>Yes it is 2. All of the other numbers were odd which made it kind of obvious =P</p>
<p>Trixee - I couldn't find the part that said geese were endothermic or not...it just said that endothermic animals contain coliform bacteria in their intestines. Haha oh well. Hoping for a 35 in Science with -1.</p>
