A man in dress pants and a blue dress shirt is walking in the shadows of nature.
a woman at the beach
The two sentences contradict each other because the above sentences include two different sexes, one female and the other male. Also, the woman is just at the beach while the man is walking in a natural place.
One cannot be in the shadows of nature and at a beach, as a beach does not have natural shadows because there are no trees.
A man is a male and a woman is a female.
