Questions $3$ through $7$ ask about the highest level of normalization each table achieves. Keep in mind that each level of normalization builds on the last. If a table is not in $1$NF$,$ there's no way it can be in $2$NF$.$ If it's not in $2$NF$,$ there's no way it can be in $3$NF$.$ To answer these questions, you should first check if the table is in $1$NF; then, if it passes $1$NF$,$ check for $2$NF$,$ etc. What is the highest level of normalization the following table achieves?
