a
Most of Albarran's █████ ████ ███ ███ ███████ ████ ██████████ ███ ██████ █████████
Could be false. We can say that some of her works that aren’t popular with collectors are highly original, but we don’t know that most of these paintings are highly original.
b
Few of the █████ ████████ ████ ██ ██████████ ██████ ███ ████████ ██████
Could be false. We just don’t know what quantity of her late works are abstract works.
c
Most, if not ████ ██ ███ █████ ████████ ████ ██ ██████████ ██████ ███ ███ ██████████
Could be false. We know that all oil paintings were produced late in her career; we don’t know what quantity of her late career works are oil paintings.
d
Most, if not ████ ██ ██████████ ████████ █████ ███ ███ ███ ██████████
Must be true. As shown below, by chaining /highly original with /oil paintings, we can make the valid argument that most of her abstract works are not oil paintings.
e
Few or none ██ ██████████ ██████████ █████████ █████ ███ ██████ █████████
Could be false. (E) can be understood to say “most of her critically acclaimed works are not highly original.” We can say that some of the non-critically acclaimed works are highly original, but we cannot make the inference that (E) makes.
