b) Names are important in grammars, just as in programming. Programming is a form of communication, not with the computer but with other humans who will read your program, and you should help them understand the program. One part of that is to chose good names for variables and other things.
Christmas!
Done!
Glad
Merry
Midsommar!
Påsk!
Trevlig
or perhaps these nine:
Christmas
Done
Glad
Merry
Midsommar
Påsk
Trevlig

Deriving this token sequence from the start symbol statement-list, using the productions in the grammar. That a terminal is underlined just means that it will be expanded in the next step. We have always expanded the leftmost non-terminal, but that is not necessary. In the final step, we use the production statement-list -> empty.

statement statement-list
if ( condition ) statement statement-list
if ( variable < variable ) statement statement-list
if ( variable < variable ) if ( condition ) statement statement-list
if ( variable < variable ) if ( variable < variable ) statement statement-list
if ( variable < variable ) if ( variable < variable ) variable = integer-literal ; statement-list
if ( variable < variable ) if ( variable < variable ) variable = integer-literal ; statement statement-list
if ( variable < variable ) if ( variable < variable ) variable = integer-literal ; variable = integer-literal ; statement-list
if ( variable < variable ) if ( variable < variable ) variable = integer-literal ; variable = integer-literal ;
