chose the right option  1) if x,y ∈Q^c  and x<y  then ∃a∈Q  such that x<a<y in case we say that  a)Q^c  is an ordered field  b)Q dense inQ^c   c)not ordered field    2)let Q≠A ∈ Q,A not necessary has  least upper bound and greatest lower  bound that mean (Q,+,.,≤)is.......  a)not complete  b)complete  c)dense in R    3)the sequence a_n =(n/(n+1)) is convergent  to......  a)0  b)1  3)∞    4) let f:A→B be a real valued function  and Q≠S⊆A such that f is not continuous  on S  then f is  a)contiuous on A  b) continuous at any points x_0  in  A  c) continuous on  A/S    4)every set of natural numbers has  a least element so the order set of  natural number is......  a)bounded from above  b)bounded from below  c)well ordered
