It would be the one about the hikers!
They can see their silhouettes on the hill (the outline of their shadows)

The quote is all about nature, and D is the only one about nature, so I'd say that's the best answer.
The Broadway show "Movin' Out" was based on songs written by the songwriter named Billy Joel.
The musical features many of his songs, among which is of course the eponymous song Movin' Out (Anthony's Song), released in 1977 on his album The Stranger. It was an immediate hit, and it influenced many other artistic performances as well.
I would have to say that the best way to revise sentence four is by changing "aren't" and "they're" to "are not" and "they are."
"Argue" works better than "fight."
Deleting the entire sentence would remove the transition into cost efficiency of the tablets.
And moving the sentence to the end would place the transition to cost efficiency in the wrong place.
