Which paraphrase best expresses the meaning of the word although?
Read the passage from "Flowers for Algernon."
As I review the records and data on Algernon, I see
that although he is still in his physical infancy, he has
regressed mentally. Motor activity is impaired; there is
a general reduction of glandular activity; there is an
accelerated loss of coordination.
O Algernon is going backward mentally, similar to other
young mice, which was not expected.
O First Algernon was young, then he went backward
mentally, which was not expected.
O As a result of being a young mouse, Algernon is
going backward mentally, as one would expect.
O Algernon is still a young mouse, but he is going
backward mentally, in contrast to what one would
expect.
