Ключи предназначены исключительно для самопроверки. Любой язык предполагает возможность выразить одну и ту же мысль несколькими способами, поэтому всегда лучше думать самостоятельно и обращаться к готовым ответам лишь в случае затруднений. Кроме того, любой опытный учитель с легкостью отличит самостоятельно выполненную работу учащегося от списанной с ключей.
