A curious child attempting to fish what nature flushed ashore with a beautiful ocean background.
The child is enjoying a beautiful day at the beach with his/her family.
A child fishing does not imply the child is enjoying the activity. A beautiful ocean background does not imply the day is beautiful. The weather could be bad.  A beautiful ocean background does not imply the child is at a beach. The background cold be wallpaper. A child does not necessarily have to be at a location with his/her family.    Comment: It's a little hard sometimes to phrase what I wont when the highlighted words have to match exactly. For example I want to say a child does not have to enjoy themselves while fishing. Figuring out different ways to word the sentence to incorporate 'enjoying' can be tricky.
