Work Step by Step
Continuing from the previous table, the second student (Jhon) currently has one sibling (Marry) and one major (Maths).
To add a second major — say, Computer Science — we must duplicate Jhon’s row (because each row can store only one major):
\[
\begin{array}{|c|c|c|c|}
\hline
\textbf{Student} & \textbf{Student} & \textbf{Sibling} & \textbf{Major} \\
\textbf{Number} & \textbf{Name} & \textbf{Name} \\ \hline
1 & Noor & Kaya & History \\ \hline
1 & Noor & Maya & History \\ \hline
1 & Noor & Dani & History \\ \hline
2 & Jhon & Marry & Maths \\ \hline
2 & Jhon & Marry & ComputerScience \\ \hline
\end{array}
\]
