The detail "...make sure they are not touching each other..." best supports the inference that one bad apple can spoil all the others. As stated in the text, the fruits are stored in the hoard house for future consumption. It is important that one does not contain a bruise since this will also affect the others around it.
Setting and tone/mood can be seen to go hand in hand, so to
speak. For instance, a scene of a story
or poem that takes place in a field of flower on a bright and sunny day would
contribute to a tone of happiness. That
said, the time _1984_ occurs is in the future for the characters of the
novel. The place is London, and the
weather and color are, respectively, dreary and gray. Because
the future can never be known for sure, this uncertainty contributes to the
dystopian tone. Likewise, when one
thinks about the miserable nature for people that would be caused by a dystopian
society, bright and sunny are not what one might generally think. Setting
in _1984_ contributes to the tone of dystopia because when one pictures what a
dystopia might look like, smoggy, foggy, and gray are probably what come to
mind.
