I get E..

the only finite statements are D and E..

however, D is actually 2 sep. lines..so E it is..

well.. for E i got

i have -2/3<=x and x<=2/3

so, if u draw a line x will be greater than -2/3 and will progress further towards infinity

note that x<2/3 says that x is greater then 2/3 not smaller

E:
-2/3 <= x <= 2/3

lets break it : -2/3 <= x .. means X can be -0.5 ,-0.4,0 ,1 ,4,10 so on...

x <= 2/3.. means X can be 0.5,0.4,0,-1,-4,-10 so on..

if we see whole equation we will find that x is of finite lengh.. single piece ranging from -2/3 to +2/3

okay but why E and not D?

D is also finite

D has a number of finite line segments !!!
whereas question asks for single finite line segment !!!
In GMAT most important is what question is asking for !!there can be any number of answers but only one which satisfies the requirements
