explanation: both "flowers" and "plastic flowers" are flowers, and "plastic flowers" are imitations of "flowers". both "paper book" and "e-book" are books, "paper book" is the traditional book form, and "e-book" is the modern book form. both "photos" and "portraits" are two forms of taking pictures of objects, and "portraits" are not necessarily drawn based on "photos". both "originals" and "copies" are the same type of thing, and "originals" can reproduce "copies". "seals" and "ink pads" are used together. they are indispensable.
