In this injection the a isn’t important you can use any string, but you need compare some values to return true, like 1=1, the quotes is just the string syntax, e.g. var='foo' or id=1

You might want to read up on/experiment with this subject a bit more; that should answer most basic questions.

He probably means that in the context of where it is used, it make sense. Again, find out how these things work and it should be pretty clear.

my spoiler is like this.
i don’t know to explalin without bring the answer,
but hope this can help.
just implement with query string

make the logical like
FALSE or TRUE or TRUE and FALSE

so the logical will be like
( FALSE expression OR TRUE expression) AND (TRUE ekspression OR FALSE expression)
