Seems right to me

Answer 3

but in the book answers are given as

\(\large \color{black}{\begin{align}
\begin{array}{|c|c|} \hline
1 & b \\ \hline
2 & a \\ \hline
3 & b \\ \hline
4 & c \\ \hline
\end{array}
\end{align}}\)

Answer 4

Yeah, I just figured the mistake "Hello's legal spouse and Ciao's sibling are of the same sex". Which is not the case in what you did.

Answer 5

I'll break it up. The names would take a long time to type, so I'll just type the first letter of their name. Three people named H, C, and V.
They tell you that:
H is married to C or V
C's sibling is H or V
V's sister in law is H or C
H's spouse and C's sibling is of the same sex.

We can start attacking this problem with the "V's sister in law" part. We do so through understanding the meaning of "sister in law", which means "the sister of one's spouse". What can you determine from this?
