True or false statements 
Two of the following statements are true and one is false
a) For all rational numbers $q$, there exists an integer $n$ so that $q+n=271$.
b) For all integers $n$, there exists a rational number $q$ so that $q+n=271$.
c) There exists an integer $n$ so that $271-n$ is even.

I believe a and c are true and b is false

Hints:


*

*For any integers $x$ and $y$, their difference $x-y$ is an integer.

*Every integer is a rational number.

*$\frac{1}{2}$ is a rational number.
