Axel wants to replace the word observe in the last paragraph with the word that has a positive connotation which word should he choose? a) mark b) recognize c)celebrate d) remember

C) Celebrate.  This would make better sense, since it isn't having a claim to recognize something when it already is a holiday. Observing something would simply be to inspect.  Mark is definitely not your answer and you should know that the last ones available aren't reasonable!  So the answer is C)

an old person

explanation:

faith or loyalty when pledged in a solemn agreement or undertaking.
