<p>The following question was number 48 on the collegeboard released exam for the math level 2 SAT subject test</p>
<p>Which of the following has an element that is less than any other element in that set?</p>
<p>I. The set of positive rational numbers
II. The set of positive rational numbers r such that (r^2) is greater than or equal to 2
III. The set of positive rational numbers r such that (r^2) is greater than 4</p>
<p>a) None
b) I only
c) II only
d) III only
e) I and III</p>
<p>The answer was apparently a. I'm so confused!</p>
<p>ok so root 2 is irrational sam with root 5 making the lowest possible number in the set ineefective whereas in 1 1 is the lowest possible number nd is effective</p>
<p>"less than" as in smaller value than? every set has a smallest number in it? I got a 790 when I took this and I don't even understand what this question is asking!</p>
<p>i think the whole exam this question came from was a lot harder than the other released exam...oh well, i just hope it's not like that tomorrow.</p>
<p>There wasn't anything this weird on the May test...it was hard but there weren't a lot of I,II,IIIs like this. I honestly just don't understand what this is getting at...I think they're very careful with the real tests so that all questions are fair and not unnecessarily confusing. Good luck tomorrow!</p>
<p>I understand it now...hopefully there is nothing like that tomorrow.</p>
<p>Nygirl - basically the question requires you to know that as a number approaches something, it is not going to be a really small rational number.</p>
<p>.000000001 is smaller than .00001, but you can keep going forever and reach a rational number</p>
