Question

Which number indicates good speakers who are neither politicians nor professors?

• A. $6$
• B. $2$
• C. $5$
• D. $1$

Answer 1

Answer: (B)

$2$

Circle for $good$ $speakers$ has $2$,$4$,$5$ and $7$. But we have to find $only$ those in $L$ where $M$ and $N$ do $no$t have an $intersection$. So, this $rules$ $out$ $5$,$7$ and $4$. In the $end$, $only$ $2$ is $left$. So, option $B$ is correct.
