Question 44

Given the true statements:

$1.$ If $a$ is greater than $b,$ then $c$ is greater than $d.$

$2.$ If $c$ is less than $d,$ then $e$ is greater than $f.$

A valid conclusion is:

If $a$ is less than $b,$ then $e$ is greater than
$f$
If $e$ is greater than $f,$ then $a$ is less than
$b$
If $e$ is less than $f,$ then $a$ is greater than
$b$
If $a$ is greater than $b,$ then $e$ is less than
$f$
none of these
